Title:
TOF CAMERA AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/114036
Kind Code:
A1
Abstract:
A TOF camera (100) and an electronic device. The TOF camera (100) comprises a light emission module (10), a lens module (20), a reflection piece (30), a rotating module (40) and an image processing module (50). The rotating module (40) drives the reflection piece (30) to rotate. The image processing module (50) receives images collected by the lens module (20) to perform splicing processing, so as to acquire a complete image of a photographed object (60). The minimum distance between a region boundary of a reflection surface (31) of the reflection piece (30) within a field of view range of the lens module (20) and a circumferential edge of the reflection surface (31) is not less than 0.2 mm. The reflection piece (30) reflects natural light and modulated light into the lens module (20) multiple times, and no further processing is performed on the image, such that the number of pixels of a single partial image of the photographed object is higher; in addition, the distance between the region boundary of the reflection surface (31) within the field of view range of the lens module (20) and the edge of the reflection surface (31) is not less than 0.2 mm, which ensures that the reflection piece (30) fully reflects the natural light and modulated light, thereby guaranteeing the quality of the image formed by the lens module (20).
