摘要： A power switching device for switching power between translational motion and rotational motion includes an active gear, a transmission mechanism, a translation mechanism, a functional gear, and a reset mechanism. The active gear can rotate in a first direction or a second direction opposite the first direction. The translation mechanism includes a runner and a pushing member. The active gear can switch between a first position and a second position. In the first position, the active gear meshes with the runner and rotates in the first direction or the second direction to drive the runner to rotate. In the second position, the active gear meshes with the transmission gear and rotates in the second direction to drive the functional gear to rotate.

摘要： A method for detecting whether a face is masked includes acquiring a face image to be recognized; performing face detection on the face image to be recognized to determine a first face area; preprocessing the first face area to obtain a first square face image; performing face recognition on the first square face image using a face recognition model and outputting a result of recognition or non-recognition. The method of the present disclosure obtains a square face area by preprocessing face detection results, optimizing the process flow of masked-face recognition, and improves the accuracy of recognition.
