Abstract

The embodiment of the invention discloses a projection device, which is applied to a mobile terminal and comprises a processor, an infrared time-of-flight distance measuring sensor, a structured lightassembly and a visible light projector. The processor is used for controlling the infrared time-of-flight distance measuring sensor to determine depth information of a target carrier; the processor is used for comparing depth information with a set threshold value to obtain a comparison result; according to the comparison result, the processor controls the structured light assembly to collect three-dimensional feature information of the target carrier; the processor is used for superposing virtual data with the target carrier according to the three-dimensional feature information of the target carrier; and the visible light projector is used for projecting data generated by superposing the virtual data and the target carrier. The embodiment of the invention further discloses a projectionmethod and a computer readable storage medium.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of terminal projection, and relates to but not limited to a projection device, a method, and a computer-readable storage medium. Background technique [0002] Augmented Reality (AR) is a combination of real scenes and virtual scenes. Based on the picture taken by the camera, the virtual data is superimposed on the real environment through computer processing capabilities, and then the same picture is used for display. An interactive mode. Existing AR projection technology is mainly embodied in projector products, using key technologies such as image recognition, 3D reconstruction and automatic three-dimensional mapping, and real-time identification of targets in the projection interface through the camera next to the projection lens (usually an infrared camera) The carrier uses the powerful computing power of the host to map the preset content to the target carrier. [0003] Existing por...
