Abstract

The invention discloses a touch recognition method based on depth-of-field projection, which includes: using depth-of-field module data to extract touch interference feature areas in real-scene images; marking the time of touch interference feature areas; when the time exceeds a preset time threshold, then Save the touch interference feature area into the background image; perform differential processing on the real scene image and the background image to obtain the differential image; perform touch recognition processing on the differential image, and perform touch operations according to the touch recognition result; the The method can identify data corresponding to non-user touch operations in the depth of field module data, which can reduce misoperations and improve user experience; the invention discloses a depth of field data acquisition device, a projection component, a terminal device, and a computer-readable storage medium. The beneficial effects mentioned above.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to a touch recognition method, device, projection component, terminal device and computer-readable storage medium based on depth-of-field projection. Background technique [0002] At present, the user can use the depth image to perform gesture recognition of the projected image, so as to operate the operating system. In actual use, when using depth of field data for gesture recognition, we often encounter such a situation: because the depth of field projection surface is larger than the vertical projection surface, and the depth of field projection surface is scanned with infrared, it is invisible. Therefore, users often place their hands or other objects such as tea cups into the depth-of-field projection surface, or when users interact, they habitually place their arms in the vertical projection area. The above phenomenon will cause the touch recognition alg...
