How to extend the effective detection range
Jason-wwww opened this issue · 1 comments
In order to extend the effective detection range, I modify the value of "target_assigner", "test_config" and "voxel_generator" in the config file.
anchor_ranges=[0, -40.0, -1.0, 70.4, 40.0, 1.0]
->anchor_ranges=[0, -40.0, -1.0, 102.4, 40.0, 1.0]
in "target_assigner"
range=[0, -40.0, -3.0, 70.4, 40.0, 1.0]
-> anchor_ranges=[0, -40.0, -3.0, 102.4, 40.0, 1.0]
in "voxel_generator"
post_center_limit_range=[0, -40.0, -5.0, 70.4, 40.0, 5.0]
-> anchor_ranges=[0, -40.0, -5.0, 102.4, 40.0, 5.0]
in "test_config"
However, the effective detection range is also about 70m. What can I do to extend the effective detection range?
@Jason-wwww Do you test it on KITTI or a new dataset? If on KITTI, there may exist very few points out of 70m range. If on a new dataset, I wonder if there exist enough points for the long-distance objects. For your revisions, I think they are right, while I'm not sure if they are enough as I don't remember too much, but I suggest you to check more on the results before NMS -> then the confidence maps of the detection head, by this way, you should find out how to address it.
