Abstract

The invention relates to the technical field of machine vision, in particular to a moving direction detection method and device, projection equipment and a readable storage medium. According to the moving direction detection method provided by the embodiment of the invention, the first feature region can be directly determined from the acquired first projection scene image; a second feature regionis determined from the acquired second projection scene image, the first feature region and the second feature region comprise the image information of the pedestrian in the projection scene, and theimage acquisition time corresponding to the second projection scene image is located after the image acquisition time corresponding to the first projection scene image; therefore, the moving direction of the pedestrian in the projection scene can be obtained according to the comparison result of the first coordinate information and the second coordinate information, and the process has the characteristic of simple calculation logic, so that the execution efficiency of the moving direction detection method can also be ensured.

Description

technical field [0001] The present application relates to the technical field of machine vision, in particular, to a method and device for detecting a moving direction, a projection device and a readable storage medium. Background technique [0002] A projection device, also known as a projector or projector, is a device that can project images or videos onto a projection surface (eg, projection wall, projection screen). At present, projection equipment can be used for work meetings, training lectures, and game interaction. During such use, in order to realize the interaction between the speaker / gamer and the projection interface, for example, the automatic screen saver function, it is usually necessary to monitor the speaker The moving direction of the person / gamer is detected, and then according to the detection result, the effective interaction between the speaker / gamer and the projection interface is realized. However, in the prior art, no related moving direction detec...
