Issue Getting Mecheye NANO Ultra-GL Intrinsic Information Through Linux API 2.5.4

Q&A
1

Hi I am using the Mecheye Nano ultra-gl connected to a linux computer running ubuntu 20.04. I have installed your SDK v2.5.4.

I am able to connectCamera(…), getCameraInfo(…), load and save user sets to and from file, get and set parameters, capture3DWithNormal(…), and captureStereo2D(…).

My problem is that captureStereo2D(…) returns to images from two separate perspectives, and I cannot seem to figure out how to extract the pinhole camera information that describes those two images. The getCameraIntrinsics(…) camera method returns two objects of type Intrinsics2DCamera, one for “depth” and one for “texture”, how ever both seem to be identical(describing the same camera); the method also returns a Transformation, depthToTexture, but this is the identity.

I would like to be able to get the Intrinsics2DCamera info for both cameras in the stereo pair and the transformation between them. Is that possible with the linux API?

In SDK v2.5.4 (Linux), it is not possible to directly obtain the intrinsic and extrinsic parameters of both physical cameras (left and right) through the API.
The getCameraIntrinsics(…) method only returns the parameters of the main camera (left camera), and depthToTexture is an identity transformation.
If you need detailed parameters for both cameras, please contact Mech-Mind technical support, or capture the original images and perform your own calibration.
