Abstract

The invention discloses an image collection device for correction of a dual-camera module and an application method of the image collection device. The application method comprises the following steps of (1) respectively rotating a first chart map, a second chart map and a third chart map according to a first deflection angle, a second deflection angle and a third deflection angle which are set in advance; (2) respectively moving the first chart map, the second chart map and the third chart map according to a first distance, a second distance and a third distance which are set in advance; and (3) sequentially shooting the first chart map, the second chart map and the third chart map by the dual-camera module to be corrected under different focal lengths. With the adoption of the method, the three chart maps at different distances and / or different deflection angles are sequentially shot by dual cameras under different local lengths, close shot, medium shot and long shot are achieved to acquire video data required for correction of the dual-camera module, the video data is applied into a dual-camera module correction system to achieve optical axis and optical distortion compensation, and the imaging quality of the dual-camera module is further improved.

Description

technical field

[0001] The invention relates to an image acquisition device for correcting a dual camera module and a method for using the same. Background technique

[0002] Dual-camera modules have become the standard configuration of smart mobile terminals such as mobile phones, and the image quality of dual-camera modules has also become a topic of concern in the industry. The prerequisite for doing a good job with dual cameras is to ensure that the optical axes of the two cameras are parallel. At present, hardware calibration is often used to determine that the optical axes of the two cameras are parallel. However, pure hardware calibration cannot ensure that the optical axes of the two cameras are parallel, and software calibration is also required. Compensation to ensure that the optical axes of the two cameras are parallel. Contents of the invention

[0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a metho...
