Changes introduced in the new H3 dataset hot3d breaks their compatibility with some existing utility scripts (unrelated to evaluation). The two main causes are:

• file structure: hot3d scene annotations are done per stream (rgb, gray1, etc.) and the scene camera format has changed (classic datasets -> "cam_K", hot3d -> "cam_model")
• camera model: New dataset Hot3d includes fisheye camera images, which can be handled with the hand tracking toolkit camera model and rasterizer.

Candidates scripts for update:

• annotation_tools: file structure, relies on depth data (not present in HOT3d and HANDAL), assumes pinhole model (cf Scripts not compatible with H3 datasets #137 (comment))
• calc_gt_distribution: file structure, add stream choice
• calc_gt_masks: file structure, relies on depth data
• calc_gt_info: file structure, relies on depth data
• crop_image_and_gt: file structure, assumes pinhole model
• enumerate_test_targets: file structure
• render_train_imgs: file structure, assume pinhole camera
• subsample_dataset: file structure
• vis_gt_poses: file structure, assumes pinhole type rasterizer (we need to switch to bop_toolkit_lib/renderer_htt.py for hot3d).
• vis_est_poses: same as vis_gt_poses
• vis_object_symmetries: file structure, pinhole camera stored in dataset folder (could replace by a user defined cam with reasonable defaults).
