The invention discloses a method and device for PDAF calibration based on MEMS movement. The method includes: determining N preset lens positions of the lens at a preset distance from the calibration map, wherein N is a positive integer; controlled by a micro-electromechanical system MEMS The position of the image sensor and the lens deviates, so that the lens moves to the corresponding preset lens position, and the defocus value of the lens at each preset lens position is obtained respectively; phase detection is performed according to the obtained N defocus values Autofocus calibration. The PDAF calibration method based on MEMS movement provided by the embodiment of the present invention makes it unnecessary for the user to manually move the mobile terminal during the calibration process, thereby reducing the impact of the vibration of the mobile terminal on the calibration result, improving the accuracy of calibration, and simplifying the calibration operation. The steps facilitate the calibration of the PDAF, and the accurate calibration of the PDAF can improve the quality of subsequent photographed pictures.

The invention discloses a verification method and device for returned parameters of an interface, equipment and a readable storage medium. The method comprises the steps of obtaining multiple returnedparameters returned by the interface to be verified and corresponding expected parameters; storing an actual key-value pair formed by an actual path and a returned value which are included in the returned parameters and an expected key-value pair formed by an expected path and an expected value which are included in the expected parameters in a hashmap; traversing the hashmap to compare the actual path with the expected path, compare the returned value with the expected value and compare all the returned parameters and the expected parameters one by one; when all the returned parameters are compared with the expected parameters, verifying the returned parameters of the interface to be verified. According to the scheme, the hashmap is traversed to compare the returned parameters with the expected parameters, and the returned parameters of the interface to be verified are verified. The situation that verification codes are written for verification is avoided, the testing workload is reduced, the verification operation is simplified, and the testing efficiency is improved.
