OpenCV 3.2 Multitracker Read Access Violation

asked 2018-11-08 10:20:51 -0500


When i use the Multitracker, i get after 4-8 hours a Read Access Violation 0xC0000005 when the Tracker updates the Image. The Error happened at copyMakeBorder_u8 line 1070. I checked that the Image is not a nullpointer when i call Tracker->update(Image). Maybe someone has a solution for me.

3.2 did not have "debug guards", so chances are, that you accidentally linked opencv debug libs to a release project (or the other way round)

can you take a (sharp !) look at your project's linker settings ?

then, it's probably a good idea to update booth of opencv and opencv_contrib to latest 3.4 branch,

-- 3-2-0 is 2 years old !

Hey, thank you for you Response. I checked the linker Settings, but i didnt see any debug libs in my release Project. I also checked the pointers at copyMakeBorder_u8 again and the src Pointer is Null and the dst Pointer ist not Null.

I thought OpenCV 3.2 is a good choice because i used it before and had no Problems with it. So you suggest to use 3.4 now?

idk. but there have been tons of changes to the "low level" stuff in the meantime. maybe just give it a try ?

I Change the build now to Version 3.4. The Problem is, that the error just show up after a few hours and so it is hard to find the reason. I will write again, after i tested it with the new Version.

yes, please do so ;)

if you can nail a bug, it has to be reported, so it can be repaired, no ?

if you use opencv_contrib libs, you MUST NOT link opencv_world (from the old, prebuilt libs) !
