Abstract

The invention relates to the method for looking for the middle position of a motor, which comprises the steps of firstly acquiring an image taken by a camera module, identifying a mark point in the image through an image detection technology, then calculating the total travel of movement of a side cover through a corresponding algorithm by using software according to variations of the mark point, and thus calculating the middle position of the motor, thereby realizing a function of looking for the middle position of the motor automatically, and improving the calibration efficiency and the success rate.

Description

technical field [0001] The invention relates to the field of mobile phone camera modules, in particular to a method for finding the center position of a magnetized ball integrated motor. Background technique [0002] With the rapid development of photoelectric technology, the application range of camera modules is becoming wider and wider, such as mobile phones, cameras, etc., and people have higher and higher requirements for the clarity of photographed pictures, which makes it particularly important to calibrate camera modules . Keeping the inclination of the optical center of the sensor (Sensor) and the lens (Lens) consistent is very important for the imaging quality of the camera module, and it is also a key factor that determines the quality of the lens module. In the actual production process, it is often corrected by equipment calibration. Ensure that the inclination of the optical center of the sensor and the lens is consistent to improve the imaging quality of the ...
