Stitching returns black image #22

Hi,

OS: Ubuntu 18.04 Camera: Insta360 X3 I want to stitch *.insp files. For this, I am using the LinuxSDK20230621.zip which you provide at the official website. Since the library requires CUDA 10.2, I utilize this docker image.

I am able to successfully build the stitcherSDKDemo binary with the provided CMake file. However, the following: ./stitcherSDKDemo -inputs ../data/IMG_20230802_132756_00_014.insp -output ../data/output.jpg results in a black output image.

Terminal output:

./stitcherSDKDemo -inputs ../data/IMG_20230802_132756_00_014.insp -output ../data/output.jpg

How can I obtain a correctly stitched image? Thanks and best regards, Thomas

@Thomas-Kb any progress with his issue?

Same problem here. There's nothing particularly obvious in the sample code that points to this behavior.

Same problem here. I asked the tech support of Insta360 for help, but got no reply......

I disabled cuda in image stitching and got the correct image. I don't know why cuda is needed for image stitching with single insp.

Thomas-Kb commented 1 year ago

Interesting, how exactly did you disable cuda? Could you provide the code?

see #27

I tried your approach. Unfortunately, it still results in a black image.

Can you share your error message? And would you mind share your image for me to have a try?
