Document Type and Number:
WIPO Patent Application WO/2016/155074
Kind Code:
A1
Abstract:
Provided are a correcting and focusing method and system for an included angle of an optical axis, and dual-camera equipment. The correcting method comprises: focusing any one feature point of a filmed object, and obtaining a first object distance value (102); determining a first imaging point coordinate value of the feature point on a first camera (104); determining a second imaging point coordinates value of the feature point on a second camera (106); and determining, according to the first imaging point coordinate value, the second imaging point coordinates value, pre-stored parameters of dual-camera equipment, the first object distance value and a preset calculation formula about the included angle of the optical axis, the included angle of the optical axis (108) of dual-camera equipment.
