Abstract
A color depth integration method, a receiver, and a light detection and ranging apparatus thereof are disclosed to integrate image capturing with 3D depth measuring efficiently. A receiver includes at least one detector macro-cell, each of which includes a first detector configured to capture reflected light and a second detector configured to capture first external light. The first detector and the second detector are arranged in an array to constitute one detector macro-cell. The reflected light represents light emitted from a transmitter and reflected by at least one object. A frequency range of the first external light and a frequency range of the reflected light is non-overlapping or at least partially non-overlapping.
