Abstract

The present invention provides a camera focusing method, including: making an imaging plane of a time-of-flight (ToF) camera and that of a red-green-blue (RGB) camera located in a common plane, obtaining a pixel column difference, a pixel matching table, and a corresponding area, calculating an average depth value of the corresponding area, calculating an adjustment distance according to the average depth value and a lens focal length, and adjusting a distance between a lens center and the imaging plane according to the adjustment distance to focus the cameras and improve a focusing speed. The present invention further provides a camera focusing system for implementing the camera focusing method.
