Probably not. LiDAR estimates the distance by detecting reflected light. It would have difficulty in shiny objects (since the specular surfaces reflect light at specific angle). So unless the sensor is perfectly aligned with the reflected path, it won’t “see” the object. Therefore, LiDAR would help in estimating the geometry of diffuse surface, but not shiny objects.
@jbhuang0604 good point mate, well I'd work in this field and see lidar uses polarization to specify the surface type and using dual wavelength emitters can help with transparent or translucent objects and at last there's a way called multi echoes processing which are to be done to distinguish between surface and it's reflectivity And using RGB data one can make a proper 3d reconstruction of the object and environment surrounding it... Just like apple does but not quite accurate.. I was in game development and i used these techniques to create 3d version of object but that time it was just limited to shape size and albedo but now it's far more developed..
Wow! That’s cool! Yup, LiDAR usually has difficulty in working with reflective and transparent surfaces. It’s interesting that you could handle these challenging cases.

that is a smart way to fix some issues and i need it!
Very cool!
Would it be better if your lidar to accurately measure distance of various objects in environment

nice
Glad you liked it!
Are you Nvidia engineer?
Nope!
@jbhuang0604 just that you are presenting the algorithm as "we".
Ah! Got it. This is a collaborative work between Google and University of Maryland College Park.
Among us
That’s right!
