image descriptionimage description(/upfiles/14449968823861101.jpg) I'm building the Opencv stitching project by adding the available files by myself. The project gets build without any error but there is an error, when I run it without debugging. I'm using static libraries. The error is shown in this screenshot. When I debug this program then it throws the following message while going from line no. 97 to line no. 98.

Error when debugged: "First-chance exception at 0x000007FEDB3CC7CB (opencv_world300.dll) in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

If there is a handler for this exception, the program may be safely continued."

Thank-you in advance.

Okay, screenshots with debug errors --> avoid those. They are unreadable and clog up a topic. Secondly, provide the code that you are running, which file and what exact piece of code is generating this error? It seems to me that you are trying to read something which is in a directory where you do not have reading rights OR you are trying to load something from memory that is not there.

Are you sure you have loaded the images? it seems to be an empty address

I'm using this website first time so, sorry for any inconvinience in reading the code

MkZHh, next time, code should go into your question , not into a comment. also there's a "10101" button for code formatting. you'll learn ;) (no prob, we all start like this)

I'm neither using CUDA nor OPENCL or etc. I'm only opencv 3.0 on Windows 7 and x64 platform. I've added the following header files: autocalib, blenders, camera exposure_compensate, matchers, motion_estimators, opencl_kernels_stitching, opencv, seam_finders, stitching, timelapsers, util, util_inl, wrapers, wrapers_inl. The CPP files are: blenders, camera exposure_compensate, matchers, motion_estimators, opencl_kernels_stitching, seam_finders, stitching, timelapsers, util, wrapers, wrapers_cuda

You're missing an "o" here: Stitcher::Status stitcherStatus = stitcher.stitch(imgs,panramaImage); (should be Stitcher::Status stitcherStatus = stitcher.stitch(imgs,panoramaImage);)

While I was decreasing the spaces between the lines, this "o" was erased but actually, it is present in my code as I've checked it. So, the problem lies somewhere else.

Acccording to Matlab the size of the two images are 600x400 each and the images are present in the directory.If I just write a code in the same file with imread command to just read image and then imshow command.Then the image is displayed correctly as the result.How can I avoid this problem that I've told you above. It seems that the data goes into "imgs" but in the stitcher.cpp (that comes with stitching directory), the "estimatetransform" gets no data. I think that the problem lies there. As you are an expert so, you can tell it better that where is the problem and what should be its solution. :) Please ignore the screenshot and consider this error written in the first statement:

I see no estimateTransform in the code you have posted...

@MkZHh could you provide the images?

The problem with your program is that: you compiled the solution (project) in Debug mode but your .dll file (of OpenCV) was built in Release mode. I have tested your code and encountered the same error when run the program built in Debug mode with .dll files built in Release mode. Hence, to solve the problem, just switch to Release mode and rebuild your solution. And remember this statement:

imshow("Panorama image", panoramaImage);

before the waitKey(0); line.

Thank-you all. I tried using @LBerger's method and it worked well but I've to use Microsoft Visual Studio 2013 Win 64 instead of Microsoft Visual Studio 2013 and although I've 64-bit Windows but I've to build using Win32 platform in Visual Studio for perfect build and run.
