An runtime error: OpenCV Error: Assertion failed (src1.type() == src2.type())

[haoweix]

The problem occurred when run ./a.out. Specifically, it shows as following. As shown in the Issue#52, this may happens because the images are an unexpected data type. It may be due to a switch between 16 and 8 bit inputs. But I don't know how to solve that problem?

I use Opencv2.4.13, CUDA 8.0, Ubuntu 14.04 LTS and GTX 740M.

The same problem.
Ubuntu 14.04
OpenCV 2.4.13.2
CUDA: 8.0

@Harvey222, @striversist

I assume you are running the default branch of OpenDTAM: 2.4.9_experimental.

This branch was tested with opencv-2.4.9, so using this version is recommended instead of opencv-2.4.13.

Also it would be helpful if you provided a full stack trace. The output listing doesn't mention which OpenDTAM function triggered the opencv exception.

If you have trouble using cuda-gdb, try with plain gdb first.

@ravich2-7183 Thank you for your help. I will try to use OpenCV2.4.9 to see if the problem would be solved.
