Problems solved by technology
[0003] Correspondingly, the manufacturing and production requirements of the dual-camera module are very strict. For example, the positions of the first camera unit and the second camera unit of the dual-camera module will affect the imaging quality of the dual-camera module. Therefore, in the prior art It is often necessary to correct or compensate the offset position of the camera unit through various methods during the manufacture or use of the dual camera module, and fix the first camera unit and the second camera unit at the calibration position during the manufacture of the dual camera module Finally, there may be a relative tilt angle between the first camera unit and the second camera unit (see figure 1 shown) and the relative rotation angle (see figure 2 shown), which will also affect the imaging quality of the dual camera module
However, in the prior art, there is no method that can accurately measure the relative tilt angle and relative rotation angle of the dual-camera module

The invention discloses a detection method and equipment for a double-camera-shooting-unit module. The double-camera-shooting-unit module comprises a first camera shooting unit and a second camera shooting unit. The method comprises the following steps that: after the first camera shooting unit and the second camera shooting unit finish being arranged according to calibration positions, triggering the double-camera-shooting-unit module to be arranged on a double-cross pattern above the double-camera-shooting-unit module in parallel to obtain a first detection image shot by the first camera shooting unit and a second detection image shot by the second camera shooting unit; and according to the first detection image and the second detection image, obtaining detection parameters for obtaining a detection result of the double-camera-shooting-unit module. According to the method, the relative inclination angle and the relative rotation angle of the double-camera-shooting-unit module can be quickly and accurately obtained, and the method is simple in implementation and easy in popularization.
Description
technical field [0001] The present invention relates to the technical field of imaging, and more specifically, to a detection method and equipment for a dual-camera module. Background technique [0002] With the development of camera technology, the application of dual-camera modules including the first camera unit and the second camera unit is becoming more and more extensive. The dual-camera module can capture images through two camera units and synthesize them through two images. Get higher camera quality. [0003] Correspondingly, the manufacturing and production requirements of the dual-camera module are very strict. For example, the positions of the first camera unit and the second camera unit of the dual-camera module will affect the imaging quality of the dual-camera module. Therefore, in the prior art It is often necessary to correct or compensate the offset position of the camera unit through various methods during the manufacture or use of the dual camera module,...
