how to generate *custom* object coordinates

Hello, I am trying to use ZED 2i stereo camera for dynamic monitoring of our lab specimen at the structural mechanics laboratory. we have a 4 storey tall lab building on a shaking table and want to capture deflected shape during earthquake simulation. Although now we can track human body, we could not find the way to generate a custom made geometry. The building will have 4 joints at the corners of its rectangular decks and 5 times repeated by 4 joints at the floor, 4 joints at the 1st floor, … so a total of 20 joints. each joint at corners are connected together representing vertical columns as bones in the body. 4 bones on each storey to get the shape of the slab. it is a simple geometry but we don’t know how to generate a joint and bone data file. I tried to find Body_38 file to modify its joints and bone structure but could not find any file with coordinates and connectivity information. Please help.

Hi @aturer,

Welcome to the Stereolabs forums :wave:

We do not currently have algorithms to perform 3D tracking of generic objects. Using the Body Tracking model for this use case will not work as our detection model has been trained specifically on human bodies and generates keypoints for the human body joints.

Such a feature is not on our roadmap, so a way you can do this is to perform 2D detection of your points of interest, and scan the point cloud to estimate the 3d position of the joint.
