For example, a camera employing a time-of-flight sensor utilizes time-of-flight sensor measurements to determine the distance between the camera and an object or environment, and generates an image from a single measurement point. At present, time-of-flight sensor applications are mainly focused on laser-based scannerless lidar imaging systems, motion sensing and tracking, machine vision and autopilot target detection, terrain mapping, and the like. In this embodiment, the time-of-flight sensor is used in a manner that the total time of the light pulse signal propagating to the approaching hand and reflected back to the sensor is accurately measured by the time-of-flight sensor.

s025, acquiring the position distance and the moving speed of the hand according to the time difference and the phase difference of the distance-time curve;
and S026, judging the moving direction of the hand according to the position distance and moving speed of the hand.
Specifically, as a result of the relationship between the hand motions, please refer to fig. 3, the optical pulse signals reflected and returned by the hand have significant time difference and phase difference on the distance-time curve, so as to obtain the position distance, moving speed and moving direction of the hand, and further identify the gesture actions performed by the user at that time, such as waving the hand from top to bottom or waving the hand from bottom to top, waving the hand from left to right or waving the hand from right to left.
