test data for opencv/opencv#17570

+130Mb

Not allowed.

Large files (models, >1Mb) for DNN should be stored on external resources (Google Drive, DropBox, OneDrive, etc).

Test images should be kept small (no need to store FullHD images in PNG format - 320x240 may be enough for regression test)

@alalek I have already uploaded the model weights to Google Drive:

1. crnn.onnx: https://drive.google.com/file/d/1ooaLR-rkTl8jdpGy1DoQs0-X0lQsB6Fj/view?usp=sharing
2. DB_IC15_resnet50.onnx: https://drive.google.com/file/d/1cmAs91yFRyC2LC3nTTBNNYooyEmb0i5t/view?usp=sharing
3. DB_TD500_resnet50.onnx: https://drive.google.com/file/d/1_9KB6QkIghp2VNZti_dJ3Araz-nDZBsL/view?usp=sharing

Then, I should resize the test images, and only put the images to the new branch? How about the model weights?
Thanks in advance.

Put links on models weights into sample/documentation. So Users can download these files by using provided links.
In samples assume that these external files are located in the current folder.

For tests, see https://github.com/opencv/opencv_extra/blob/master/testdata/dnn/download_models.py (including this file history and related PRs). Use cvtest::findDataFile() with required=False (share on CI is updated manually, so files may missing)

@alalek
sorry, this is my first time to pull a request, and I am not sure whether I successfully squash my commits.
If I make a mistake again, can I just close this pr, and open a new one?

[alalek]

just close this

Do NOT do that. Just push your changes with "--force" option.

git reset --hard b9d7d2b83efe552b3eb43ea9311e1e53f01456dd
git push --force ...
