Method and system for testing relative tilt angle before assembly of dual-camera module

Abstract

The invention provides a method and system for testing a relative inclination angle before the assembly of a double-camera module. The method comprises the following steps: setting at least three regular geometric figures on a test chart to serve as shooting object points of the double-camera module, wherein the double-camera module comprises a first camera module and a second camera module; separately obtaining center coordinates of corresponding imaging points of the object points on the first and second camera modules, and obtaining distances from the object points to an upper surface of alens of the double-camera module on the Z axis direction according to the obtained center coordinates of the imaging points; establishing a space coordinate system, and obtaining space coordinates ofthe object points and the imaging points; and establishing an object point plane equation according to the space coordinates of the object points, establishing an imaging point plane equation according to the space coordinates of the imaging points, and obtaining the relative inclination angle of the double-camera module according to the established plane equations. By adoption of the method and system provided by the invention, the relative inclination angle of the double-camera module can be accurately measured.

Description

technical field [0001] The present invention relates to the technical field of photography, and more specifically, to a method and system for testing relative tilt angles before assembly of a dual-camera module. Background technique [0002] With the development of camera technology, the application of dual-camera modules including two camera units is becoming more and more widespread. The dual-camera module can capture images through two camera units and combine the two images captured by the two camera units. to get higher quality images. [0003] Compared with the traditional single-camera module, the manufacturing and production requirements of the dual-camera module are very strict. For example, the positions of the two camera units of the dual-camera module will affect the imaging quality of the dual-camera module. Therefore, currently During the manufacture or use of the dual-camera module, the offset position of the camera unit will be corrected or compensated by va...
