D455 depth camera point cloud
MartyG I am using realsense D455 camera. My question is when we want to save a point cloud, is it only based on the depth data, i.e., the stream that is enabled via depth sensor? Imagine that as a ...

orientation of a point in the camera coordinate system
MartyX Grover We have approaches that return 3d point in the camera reference frame, given a 2d pixel point. Is there any method, or approach that can given us the rotation / orientation of a point...

efficient way to retrieve 3d mapping for several 2d pixel points
MartyG I have several points that I want to retrieve 3d mapping. I have a bounding box of some object(s) in the scene. I am listing all the pixel points that lie within this bounding box. My idea i...

coordinate mapping issue between data captured in separate functions
MartyG Following on some previous discussions regarding mapping between 2D pixel points and 3D coordinates, I have some points that I'd like to make. Of the three methods suggested for calculating...

D455 the coordinate frames
MartyG I have tested the functions to find 3D position of a given pixel point using methods suggested in other post. My question is what is the origin of the coordinate frame here, and it is locate...

some information needed about D455
Hi, As a new person to the computer vision field, I recently started using the "intel realsense 455" camera. I can see, there appear to be 4 sensors on the camera. I understand, one of these is to ...
