Model Zoo

Dataset	Weight	Condition
WHU-TLC	46.7MB	1 * NIVIDA A6000
DTU	177MB	4 * NIVIDA T4

Due to the large differences in the datasets, we use different data processing methods and different warping methods, which leads to the full version of the code being slightly different when applying our method to the two datasets as above. However, it is important to emphasize that the core design of our code is consistent.

Data Preparation

To evaluate/train this method, you will need to download the required datasets.

WHU-TLC Please rename the "open_dataset" to "open_dataset_rpc".
DTU (training data)
DTU (Depths raw)
DTU (testing data)

By default dataset_root in train.py, we will search for the datasets in these locations. You can create symbolic links to wherever the datasets were downloaded in the data folder

Train

Train on WHU-TLC dataset using RPC warping:

python train.py --mode="train" --model="red" --geo_model="rpc" --dataset_root=[Your dataset root] --batch_size=1 --min_interval=[GSD(resolution of the image)] --gpu_id="0"

Train on WHU-TLC dataset using homography warping:

python train.py --mode="train" --model="red" --geo_model="pinhole" --dataset_root=[Your dataset root] --batch_size=1 --min_interval=[GSD(resolution of the image)] --gpu_id="0"

Predict

If you want to predict your own dataset, you need to If you want to predict on your own dataset, you need to first organize your dataset into a folder similar to the WHU-TLC dataset. And then run:

python predict.py --model="red" --geo_model="rpc" --dataset_root=[Your dataset] --loadckpt=[A checkpoint]
