Abstract

The invention discloses a device and a method for self-adaptively detecting and adjusting optical axes of dual cameras. The device comprises a parallel light pipe, a distance measurement camera, two LED targets, a computer and dual six-axis precise adjustment units, wherein the distance measurement camera is arranged at a front end of the parallel light pipe; the two LED targets are arranged at the two sides of the parallel light pipe; camera modules are respectively clamped onto the six-axis precise adjustment units; the two camera modules simultaneously carry out imaging on star points in the parallel light pipe and on the two LED targets; the computer computes deviation angles of the optical axes of the two camera modules with a central axis of the parallel light pipe and a connecting line direction of the two LED targets, and adjusts so that the optical axes of the two camera modules are respectively parallel to the central axis of the parallel light pipe, and sensor pixel array directions are respectively parallel to the connecting line direction of the two LED targets; the distance measurement camera carries out the imaging on the two camera modules, and simultaneously adjusts positions of the two camera modules, so that a distance between the two camera modules is fixed; and at last, curing is carried out on the positions of the two camera modules. According to the device and the method disclosed by the invention, the active alignment of the dual camera modules can be realized, and the accuracy is higher.

Description

technical field [0001] The invention belongs to the technical field of dual-camera modules, and relates to a device for adaptively detecting and adjusting the relative position of a dual-camera module. Device and method for sensor pixel array direction and relative distance. Background technique [0002] At present, dual cameras have been more and more widely used in many electronic products. The demand on mobile phones alone is 150,000 to 200,000 per year. Dual cameras are assembled and fixed on two single cameras. The optical axes of the camera modules are parallel to each other. However, the current supply chain for dual camera modules is immature, and low precision and efficiency are two major problems. Truly Optoelectronics Co., Ltd. proposes to first take a picture of a form with dual cameras, and then combine the establishment of the respective coordinate axes of the two modules to obtain the offset angle of the two cameras through an algorithm, and then fix a certa...
