Tracking arbitrary objects

[manushreegangwar]

I wish to use libISR to track arbitrary objects. Is it possible to use LibISR for this purpose? Please suggest modifications to the pipeline. Also, is it possible to introduce new objects into the scene while it is being scanned?

In order to track arbitrary objects, you need to create your own SDF *.bin for the object. I wrote a script to convert *.stl's to *.bin's using libIGL.Their Signed Distance tutorial is a good place to start: https://github.com/libigl/libigl/tree/master/tutorial/704_SignedDistance

Hi, I want to use your method for tracking the objects in my scene, and I have the .stl files for them, so I was wondering if you could share the script to convert *.stl's to *.bin's that you wrote ?

Actually, i'm working on a exam project in which i need to track different kind of objects in order to control a robotic head and a moving platform so to follow the tracked object and project a specific image onto them.

I have found your git project LibISR - https://github.com/carlren/LibISR - and tested using ./demo command. This git project can help me to go on with my project but i need to convert my personal mesh in a file .bin.

I had tried several program that convert mesh .obj in SDF .bin, right now the best one is armony3D/sdfgen - https://github.com/armory3d/sdfgen - but instead of the 3D representation I obtain a cube and the tracking is unstable.

@dberm22 , please, may i ask you to share me the script code that you used to convert your mesh.stl in the file mesh.bin? Or may i ask you to explain me how to create a file.bin, compatible with LibISR, from a personal mesh?

Thank you for your kindness and attention.
