Opencv 3.2.0 errors

[andychuajl]

The work around for OpenCV 3.2 is to edit renderer.py def wrapImg()
if prj.size != 0:
pixels = cv2.remap(img, np.squeeze( np.asarray( prj[0,:] ) ).astype('float32').reshape(t_height, t_width),\
np.squeeze( np.asarray( prj[1,:] ) ).astype('float32').reshape(t_height, t_width), cv2.INTER_CUBIC)
pixels = pixels.reshape(pixels.shape[0]*pixels.shape[1], pixels.shape[2])
# pixels = pixels[:,0,:]
new_img[idx,:] = pixels

Hi every one, I'm a student from China.
Here's the blog of the whole process from install opencv to run the imput1 example
May be can help you a little

It works fine with version 3.1.0.5

I just spent the entire night trying to fix this. Just wanted to share the solution that ended up working for me:

1. The line throwing the error is an assertion. Comment the line throwing the error:
   <opencv folder>/modules/imgproc/src/imgwarp.cpp:4956: error: (-215) dst.cols < SHRT_MAX && dst.rows < SHRT_MAX && src.cols < SHRT_MAX && src.rows < SHRT_MAX in function remap
2. Recompile OpenCV (cmake, make)
3. Install it again (make install)

Hi,

I'm testing the project and I have some problems.

1. I have changed ThreeD_Model.py:63 --> contours, hierarchy = to **, contours, hierarchy =**_
   Because with opencv 3.2.0 findCountours return 3 params.
2. Now I can run the demo.py script, but when I have generated 10 images in output (always 10 images), I get this error:

OpenCV Error: Assertion failed (dst.cols < SHRT_MAX && dst.rows < SHRT_MAX && src.cols < SHRT_MAX && src.rows < SHRT_MAX) in remap, file <PATH_TO_OPENCV>/opencv-3.2.0/modules/imgproc/src/imgwarp.cpp, line 4956

Any ideas? Thanks!!!

so,how you solve this question finally?

I get the same error, even for a single image. I'm using opencv-python==3.2.0.6

Hi @zhixuanli ,
thank you very much for your help and I am sure your guide can help the community so much.

Thanks,

Hi All,
thank you for your feedback. I also got into trouble while running this with OpenCV3.

I think there is a quick fix that I used that briefly was the following:

• check which version of Opencv is running inside the code with something similar to python -c 'import cv2; print cv2.__version__'
• use the detected version to redirect the code to use OpenCV2 function in one case (the current code) or the new modified code to run smoothly with OpenCV3

I think I did this patch locally and it worked but I did not have the time to push it on the server.
So in theory there is not need to modify and recompile OpenCV3.

I will try to push the patch in case I have time.

I hope this helps,
iacopo

Hi,
I'm having the same issue here using OpenCV 3.2.0.
Is there any other solution except the one dshahrokhian posted? I couldn't find the imgwarp.cpp file.

Many thanks,
-Benny.

I've also got this issue, I've tried hacking around the problem with no success, it looks like the current solution is really just to recompile. I'm sorry that this comment does not offer any solutions but just wanted to highlight that this is not an isolated incident.

Kind regards,
Waj

[dshahrokhian]

@benibraz it's at <opencv folder>/modules/imgproc/src/imgwarp.cpp.

@WajWaraich Did you try my solution?

@dshahrokhian

Dani, thanks for your reply, I was trying to avoid having to recompile the library but I might have to now. I was planning on compiling OpenCV 3.3 and seeing whether that still contained the bug.

UPDATE 1: Upgrading to 3.3 did not help, the error simply went from line 4956 to 4944 as there have been some changes in imgwarp.cpp, I'll try commenting out the CV_Assert() line and recompile the library - see if that helps.

UPDATE 2: Got it all working by following Dani's ( @dshahrokhian ) instructions, just commented out the line that was causing the issue and recompiled and everything seems to be working smoothly.

@andychuajl where is this file?

[iacopomasi]

I think the file you need is in renderer.py

how to recompile opencv?

[secretdragon]

It works fine with version 3.1.0.5
