2018-12-31 10:32:49 -0600 | marked best answer | I am trying to stitch a few images and getting assertion errors. Image scheme is I have two images of dimensions : 600*429*3 and 600*523*3 There is a overlap between the two images. On trying to stitch I get the following error: OpenCV Error: Assertion failed (dst.cols < 0x7fff && dst.rows < 0x7fff && src.cols < 0x7fff && src.rows < 0x7fff) in remap, file /home/user/3.4.0/opencv-3.4.0/modules/imgproc/src/imgwarp.cpp, line 1749 I looked around an little bit and was suggested to comment out an Assertion in the imgwarp.cpp file. I commented it out and then I got a different error: OpenCV Error: Assertion failed (u != 0) in create, file /home/user/3.4.0/opencv-3.4.0/modules/core/src/matrix.cpp, line 436 I went ahead and commented that line as well. I recompiled and linked the .so file to my python cv2 package. The code ran fine,no errors this time, but the stitched image has a width of 30000 instead of 600. The final image is highly distorted. How do I fix this? |
