How to improve the detection of extreme aspect ratio targets
q1135718080 opened this issue · comments
My image size is 2048 * 2000, in which some crack targets are 20 pixels wide and 2000 pixels high. I can't detect them at all. What should I do？Thank you very much! @WongKinYiu
你对预设的anchor重新聚类了吗，更换数据集以及图片尺寸时，首先应该聚类得出最新的尺寸并在.cfg文件中做出更改
聚类了，大部分短的裂缝能检测到，那种2000像素长度的裂缝一个都没检测出来
