拼接报错 #2

Closed JackSparrow3 closed 1 year ago

JackSparrow3 commented 1 year ago

尝试自己拍了两个视频进行拼接，但是在线程里面报错了， 输出 roi[1620 x 1011 from (-680, 1355)] terminate called after throwing an instance of "cv::exception" what(): opencv(4.4.0) /root/app/src/opencv/modules/core/src/umatrix.cpp:299: error (-215:Assertion failed) s>=0 in function "setSize" 不知道是哪块的问题，可以共享下测试数据吗？

另外，是哪一行报的这个错

JackSparrow3 commented 1 year ago

是app.cpp 的56行，其中image_roi_vect[0].height 为-147 小于零所以报错了； 我把image_roi_vect 打印了下，是[2530x-147] ，没搞明白为什么这块是计算了个负的，是因为匹配点检测问题吗？ @duchengyao

@JackSparrow3 有时间的话你可以看一下这行所有变量的数值，是哪个值异常导致的height为负。
