In some applications of the Helios time-of-flight camera, you may need to project 3D image data from the Helios to a 2D image, and vice versa. This knowledge base article explores the mathematical concepts behind such projections, and also provides sample code.

Homogeneous coordinates

Homogenous coordinates let you represent points in space more simply, allowing you to perform operations such as translation and rotation more easily. A 3D point given by the vector,
