+# GeoLoc-UAV (GeoLoc-UAV-main)
+
+Research code for UAV geo-localization / cross-view image retrieval on the **UAV-GeoLoc (World-UAV)** dataset.
+
+- Dataset: available on Hugging Face: `https://huggingface.co/datasets/RingoWRW97/UAV-GeoLoc`
+- This folder (`GeoLoc-UAV-main`) contains training/evaluation scripts and model definitions.
+
+## What this code does
+
+The task is formulated as **retrieval**: given a UAV query image, retrieve the matching geo-referenced database (DB) image(s).
+
+- **Training**: contrastive classification via InfoNCE (implemented as `CrossEntropyLoss` on similarity matrix).
+- **Evaluation**: extract global descriptors for queries and DB, then run FAISS `IndexFlatL2` search and report **Top-1 / Top-5 / Top-10** accuracy.
+
+Two main modes exist in the code:
+
+- **`vanilia`** (spelling in code): a standard CNN/ViT backbone (`resnet18`, `dinov2_*`) + an aggregation head (`multiconvap`, `convap`, optional `LPN`).
+- **`group`**: a GroupNet-style encoder that uses a set of transformed views + point grids (scale/rotate sampling) before aggregation.
+
+## Project structure
+
+Key entry points:
+
+- `train_vanilia.py`: train a vanilla backbone (ResNet) retrieval model.
+- `train_vanilia_dino.py`: same, but with a DINOv2 backbone.
+- `train_group.py`: train the group-based model.
+- `train_group_dino.py`: group-based model with DINOv2 features.
+- `preprocess_data.py`: helper to generate train index files from scene lists.
+
+Evaluation:
+
+- `eval_simidataset_parser.py`: evaluate on World-UAV-style splits (reads a list of scene folders).
+- `eval_real_dataset.py`: evaluate on a “real” dataset layout (query_images/reference_images + gt CSV/NPY).
+- `eval_denseuav.py`: evaluate on DenseUAV-style lists (query.txt/db.txt/gt.txt).
+- `eval_real.sh`, `eval_rot.sh`: example command lines (paths are author-specific).
+
+Core modules:
+
+- `dataset/World.py`: dataset loaders for World-UAV, “real” and DenseUAV layouts.
+- `models/`: backbones, aggregators, group networks.
+- `eval/eval.py`: feature extraction + FAISS retrieval metrics.
+
+## Installation
+
+This repository does not ship a pinned `requirements.txt`. A typical working environment:
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+
+pip install -U pip
+pip install torch torchvision transformers tensorboard tqdm pillow numpy pandas h5py matplotlib opencv-python
+
+# FAISS (choose one):
+pip install faiss-cpu
+# or: pip install faiss-gpu  (if your platform provides it)
+```
+
+Notes:
+
+- Most scripts assume CUDA is available; CPU should work for evaluation but may be slow.
+- Mixed precision is enabled by default in training scripts.
+
+## Dataset format (World-UAV style)
+
+For the World-UAV dataset loaders (`WorldDatasetEvalVanilia` / `WorldDatasetEvalGroup`), the code expects a **scene folder** with:
+
+```text
+<dataset_root_dir>/
+  <scene_name>/
+    positive.json
+    semi_positive.json
+    DB/
+      img/
+        *.png
+    query/
+      height100_rot0/footage/*.jpeg
+      height100_rot45/footage/*.jpeg
+      ...
+      height150_rot315/footage/*.jpeg
+```
+
+Ground truth:
+
+- `positive.json`: maps each query key to a list of positive DB image filenames (under `DB/img/`).
+- `semi_positive.json`: optional extra positives (the code includes them in GT if present).
+
+Important:
+
+- Query images are collected across multiple height/rotation folders. The evaluator replicates GT to match the number of query images extracted (see `eval/eval.py`: `multi_num = ql.shape[0] / len(pos_gt)`).
+
+## Training index files (World-UAV style)
+
+Training loaders (`WorldDatasetTrainVanilia`, `WorldDatasetTrainGroup`) read a text file where each line contains:
+
+```text
+<relative_query_path> <label_int> <relative_db_path>
+```
+
+Example (paths are **relative** to `dataset_root_dir`):
+
+```text
+some_scene/query/height100_rot0/footage/height100_rot0_0001.jpeg 12 some_scene/DB/img/000123.png
+```
+
+The helper script `preprocess_data.py` can generate `*_query_all.txt` and `*_db_all.txt` from a file containing scene names (one per line). It is currently written with author-specific absolute paths and may require edits to:
+
+- `root`
+- `txt` (scene list file)
+- `save_path`
+
+## Quick start (training)
+
+All training scripts contain a `Configuration` dataclass with hardcoded paths like:
+
+- `dataset_root_dir`
+- `train_query_txt`
+- `val_index_txt`
+- `test_index_txt`
+
+Update them to your local paths before running.
+
+### Vanilla (ResNet)
+
+```bash
+python train_vanilia.py
+```
+
+### Vanilla (DINOv2 backbone)
+
+```bash
+python train_vanilia_dino.py
+```
+
+### Group model
+
+```bash
+python train_group.py
+```
+
+### Group model (DINO variant)
+
+```bash
+python train_group_dino.py
+```
+
+Checkpoints:
+
+- Training scripts create a timestamped directory under `config.model_path/config.model/<HHMMSS>/`
+- The best checkpoint (by average Top-1 on validation scenes) is saved as `weights_e{epoch}_{score}.pth`
+
+TensorBoard:
+
+- Vanilla scripts write under `world_vanillia/...`
+- Group script writes under `world/...`
+
+## Quick start (evaluation)
+
+### Evaluate on World-UAV scenes list
+
+Use `eval_simidataset_parser.py`. It reads a text file where each line is a scene folder name (relative to `--dataset_root`):
+
+```bash
+python eval_simidataset_parser.py \
+  --mode vanilia \
+  --dataset_root "/path/to/WorldLoc" \
+  --test_txt "/path/to/WorldLoc/Index/test.txt" \
+  --save_txt "/tmp/results.txt" \
+  --checkpoint_path "/path/to/weights.pth" \
+  --backbone_arch resnet18 \
+  --pretrain_flag False \
+  --agg_in_channels 512 \
+  --agg_out_channels 512 \
+  --agg_LPN False
+```
+
+For the group model:
+
+```bash
+python eval_simidataset_parser.py \
+  --mode group \
+  --dataset_root "/path/to/WorldLoc" \
+  --test_txt "/path/to/WorldLoc/Index/test.txt" \
+  --save_txt "/tmp/results.txt" \
+  --checkpoint_path "/path/to/weights.pth" \
+  --agg_in_channels 256 \
+  --agg_out_channels 256
+```
+
+### Evaluate on DenseUAV lists
+
+```bash
+python eval_denseuav.py \
+  --mode vanilia \
+  --dataset_query "/path/to/query.txt" \
+  --dataset_db "/path/to/db.txt" \
+  --dataset_gt "/path/to/gt.txt" \
+  --checkpoint_path "/path/to/weights.pth"
+```
+
+### Evaluate on “real” query/reference folder layout
+
+```bash
+python eval_real_dataset.py \
+  --mode vanilia \
+  --dataset_root_dir "/path/to/test_set" \
+  --checkpoint_path "/path/to/weights.pth" \
+  --save_dir_path "/tmp/geoloc-uav-real-eval"
+```
+
+## Common pitfalls / required path fixes
+
+- **Hardcoded absolute paths**: many scripts use `/media/...` paths. Replace them with your local paths.
+- **Transform config path is hardcoded in code**:
+  - `dataset/World.py` and `models/group/groupnet_dino.py` load `transform_config.json` via an absolute `json_path`.
+  - For portability, point it to `configs/transform_config.json` in this repository.
+- **Mode spelling**: the scripts use `vanilia` (not `vanilla`).

+# World-UAV-prepro
+
+Эта папка — **мой слой препроцесса/аналитики** поверх датасета **UAV-GeoLoc (World-UAV)**.
+
+Здесь нет обучения моделей. Основные артефакты:
+
+- `dataloader.py`: компактный PyTorch `Dataset`/`DataLoader` для train/eval по индекс-файлам `Index/*.txt`.
+- `dataloader_v2.py`: расширенная версия лоадера с парсингом метаданных (height/rotation), утилитами GPS/локализационной ошибки и scene-based лоадером для кастомных сплитов.
+- `analyze/`: оффлайн-скрипты, которые **проверяют структуру датасета**, **схему нарезки спутника**, и **генерируют графики/примерные картинки**.
+
+## Формат данных (ожидаемая структура датасета)
+
+Оба лоадера предполагают, что корень датасета (`root`) выглядит примерно так:
+
+```text
+<root>/
+  Country/...
+  Terrain/...
+  Rot/...
+  Index/
+    train_query.txt
+    train_db.txt
+    val_query.txt
+    val_db.txt
+    test_query.txt
+    test_db.txt
+    ... и варианты *_country.txt, *_all.txt
+```
+
+На уровне сцены (примерно):
+
+```text
+<root>/Terrain/<TerrainType>/<SceneName>/
+  positive.json
+  semi_positive.json
+  DB/
+    merge.tif
+    db_postion.txt
+    img/crop_X_Y.png
+  query/
+    height100_rot0/footage/*.jpeg
+    ...
+```
+
+## Index-файлы (ключевой интерфейс)
+
+### DB index (`*_db*.txt`)
+
+По 1 пути на строку, путь **относительно `root`**:
+
+```text
+Terrain/Mountain/Andes/DB/img/crop_0_0.png
+Terrain/Mountain/Andes/DB/img/crop_0_1.png
+...
+```
+
+### Query index (`*_query*.txt`)
+
+Формат строки:
+
+```text
+<query_path> <scene_label_int> <positive_db_1> [positive_db_2 ...]
+```
+
+Пример:
+
+```text
+Terrain/Mountain/Andes/query/height100_rot0/footage/height100_rot0_00.jpeg 12 Terrain/Mountain/Andes/DB/img/crop_10_7.png Terrain/Mountain/Andes/DB/img/crop_10_8.png
+```
+
+Важно: в путях могут встречаться пробелы (в вариантах/папках). Парсер в обоих лоадерах извлекает DB-пути по паттерну `*/DB/img/crop_*.png`, а `label` берёт как последний числовой токен перед DB-путями.
+
+## `dataloader.py` (базовый)
+
+### Что даёт
+
+- **Train**:
+  - `UAVGeoLocTrain`: `(query, positive, negative)` triplets (негатив берётся случайно из `train_db.txt`, исключая positives этого scene label).
+  - `UAVGeoLocPair`: `(query, positive)` пары (под contrastive без explicit negative).
+- **Eval**:
+  - `UAVGeoLocEval(mode="query")`: одиночные query-изображения + `label` + список `positives`.
+  - `UAVGeoLocEval(mode="db")`: одиночные DB-изображения.
+  - `eval_collate_fn`: collate, который оставляет `positives` списком (variable-length).
+- `build_dataloaders(...)`: собирает набор лоадеров на train/val/test.
+
+### Мини-пример использования
+
+```python
+from dataloader import build_dataloaders
+
+root = "/path/to/UAV-GeoLoc"
+loaders = build_dataloaders(root, split="terrain", batch_size=32, img_size=512, num_workers=4, mode="triplet")
+
+batch = next(iter(loaders["train"]))
+print(batch["query"].shape, batch["positive"].shape, batch["negative"].shape, batch["label"])
+```
+
+## `dataloader_v2.py` (расширенный)
+
+### Отличия от базовой версии
+
+- **Метаданные query**:
+  - парсит `height` и `rotation` из пути вида `height125_rot270/...`.
+  - возвращает их в батчах train/eval.
+- **GPS / локализационная ошибка**:
+  - `load_db_positions(...)`, `haversine_m(...)`
+  - `compute_localization_error(...)`: метрики ошибки в метрах по retrieval predictions (top-1 индексы DB).
+- **Утилита нарезки спутника**:
+  - `tile_satellite_image(...)`: генерирует кропы в стиле UAV-GeoLoc (stride по умолчанию `crop_size // 2`).
+- **Scene-based loader**:
+  - `UAVGeoLocScene(scene_dir=...)`: читает сцену напрямую из папки (без `Index/*.txt`), удобно для кастомных выборок/проверок (в т.ч. Rot subset).
+  - `build_rot_loader(...)`: convenience лоадер для `Rot/SouthernSuburbs`.
+
+### Мини-пример: посчитать error (м) по top-1 предсказаниям
+
+```python
+import numpy as np
+from dataloader_v2 import build_dataloaders, compute_localization_error
+
+root = "/path/to/UAV-GeoLoc"
+loaders = build_dataloaders(root, split="terrain", batch_size=64, img_size=224, num_workers=4, mode="triplet")
+q_ds = loaders["test_query"].dataset
+d_ds = loaders["test_db"].dataset
+
+# допустим, у вас есть top1 predictions как индексы DB:
+pred = np.zeros(len(q_ds), dtype=np.int64)
+stats = compute_localization_error(q_ds, d_ds, pred)
+print(stats["mean_error_m"], stats["median_error_m"], stats["num_evaluated"])
+```
+
+## Какой лоадер использовать
+
+- **Бери `dataloader.py`**, если тебе нужен минимальный, предсказуемый интерфейс:
+  - train triplets/pairs
+  - eval query/db
+  - без метаданных и без геометрии/географии
+- **Бери `dataloader_v2.py`**, если:
+  - в модели/логах важно `height` и `rotation` (например, для condition/аблаций)
+  - хочешь считать **ошибку локализации в метрах** (по `db_postion.txt`)
+  - нужно грузить сцены **напрямую из папки** (без `Index/*.txt`) или работать с `Rot` subset
+  - нужен helper для tiling спутника `tile_satellite_image(...)`
+
+На практике: **для базовых retrieval-экспериментов достаточно `dataloader.py`**, а `v2` — когда переходишь к “исследовательским” метрикам/контролю условий.
+
+## Какие `Index/*.txt` ожидаются для `terrain/country/all`
+
+Оба лоадера используют один и тот же принцип: в `Index/` лежат файлы вида:
+
+- `train_query*.txt`, `train_db*.txt`
+- `val_query*.txt`, `val_db*.txt`
+- `test_query*.txt`, `test_db*.txt`
+
+Суффиксы:
+
+- **`terrain`**: суффикс пустой (`train_query.txt`, `train_db.txt`, …)
+- **`country`**: суффикс `_country` (`train_query_country.txt`, …)
+- **`all`**: суффикс `_all` (`train_query_all.txt`, …)
+
+### Fallback-логика в `build_dataloaders`
+
+В `dataloader.py` и `dataloader_v2.py` `build_dataloaders(...)` делает сборку так:
+
+- **train**: берёт строго `Index/train_query{suffix}.txt` и `Index/train_db{suffix}.txt` для выбранного `split`
+- **val/test**:
+  - сначала пытается открыть `Index/{phase}_query{suffix}.txt` / `Index/{phase}_db{suffix}.txt`
+  - если этих файлов нет, откатывается на **несуффиксные** `Index/{phase}_query.txt` / `Index/{phase}_db.txt`
+
+Это удобно, если у тебя, например, `train_*_country.txt` есть, а `val_*_country.txt` ещё не сгенерен.
+
+## `analyze/` (оффлайн анализ датасета)
+
+Скрипты ориентированы на запуск “как есть”, но почти везде нужно поменять `BASE`/`ROOT` (путь к датасету).

+# `analyze/` — анализ структуры UAV-GeoLoc (World-UAV)
+
+Папка содержит скрипты “dataset forensics”: они проверяют, что лежит в датасете, какие размеры/распределения, и как именно нарезаны спутниковые карты в `DB/img/`.
+
+Все скрипты рассчитаны на локальный датасет и обычно требуют изменить путь к корню датасета в константах `ROOT`/`BASE`.
+
+## Скрипты
+
+### `terrain_stats.py`
+
+**Задача:** собрать подробную статистику по **Terrain subset**:
+
+- количество сцен по terrain-type
+- количество DB кропов в сцене
+- количество query вариантов и кадров
+- размеры `merge.tif` и примерный размер кропа
+- диапазоны GPS из `DB/db_postion.txt`
+- статистика `positive.json` и `semi_positive.json`
+- список всех обнаруженных `height*_rot*` вариантов
+
+Запуск:
+
+```bash
+python analyze/terrain_stats.py
+```
+
+Перед запуском поменяй:
+
+- `ROOT = ".../UAV-GeoLoc/Terrain"`
+
+### `analyze_crop_scheme.py`
+
+**Задача:** восстановить схему нарезки спутника (crop_size/stride/overlap) через попиксельное сравнение:
+
+- подтверждает, что `crop_0_0.png == merge[0:crop, 0:crop]`
+- находит `stride_x`, `stride_y` по сопоставлению `crop_1_0.png` и `crop_0_1.png`
+- выводит `overlap = crop_size - stride`
+
+Ключевой вывод (по docstring): `stride = crop_size // 2` (50% overlap).
+
+Запуск:
+
+```bash
+python analyze/analyze_crop_scheme.py
+```
+
+Важно:
+
+- скрипт использует `Image.MAX_IMAGE_PIXELS = None` из-за больших `merge.tif`
+- по умолчанию ищет сцены относительно `base = dirname(__file__)` — это может не совпадать с реальным расположением датасета. Если нужно, перепиши `patterns` под свой датасет.
+
+### `generate_charts.py`
+
+**Задача:** сгенерировать “publication-quality” графики (png) по датасету:
+
+- сцены по странам / по terrain-type
+- распределение размеров кропов
+- размеры train/val/test сплитов (по `Index/*.txt`, если доступны)
+- распределение количества positives на query (по `Index/train_query.txt`)
+- географическое покрытие (scatter по средним lat/lon сцен)
+- размеры `merge.tif` (scatter)
+- схема query вариантов (polar)
+
+Запуск:
+
+```bash
+python analyze/generate_charts.py
+```
+
+Перед запуском поменяй:
+
+- `BASE = "/.../UAV-GeoLoc"`
+
+Выход:
+
+- `CHARTS = <BASE>/charts/` (создаётся автоматически)
+
+### `generate_sample_grids.py`
+
+**Задача:** сгенерировать наглядные “grid” картинки:
+
+- query vs positive DB crop
+- сравнение высот (100/125/150)
+- сравнение поворотов (0..315)
+- визуализация tiling’а на кусочке `merge.tif` (пример crop_size=200, stride=100)
+- разнообразие terrain типов (подборка `crop_0_0.png`)
+
+Запуск:
+
+```bash
+python analyze/generate_sample_grids.py
+```
+
+Перед запуском поменяй:
+
+- `BASE = "/.../UAV-GeoLoc"`
+
+Выход:
+
+- `OUT = <BASE>/charts/`
+
+## Зависимости
+
+Типично нужны:
+
+- `numpy`
+- `Pillow`
+- `matplotlib`
+
+Дополнительно для чтения больших `merge.tif` может понадобиться достаточно RAM/диска.
