Abstract

The present application provides a three-dimensional video system including a structured light module for emitting structured light. The structured light module includes a first light-emitting unit. The first light-emitting unit receives a first pulse signal and generates a first pulse signal according to the first pulse wherein a duty cycle of the first pulse signal is less than a specific value,a light emitting power of the first light-emitting unit is greater than a specific power, and the first light has a first wavelength; and a light-sensitive pixel array is used for receiving reflectedlight corresponding to the structured light.

Description

technical field [0001] The present application relates to a three-dimensional image system, in particular to a three-dimensional image system and an electronic device capable of resisting background light. Background technique [0002] With the rapid development of science and technology, the acquisition of three-dimensional information of objects has broad application prospects in many application fields, such as production automation, human-computer interaction, medical diagnosis, reverse engineering, digital modeling, etc. Among them, the structured light three-dimensional measurement method, as a non-contact three-dimensional information acquisition technology, has been widely used because of its advantages of simple implementation, fast speed and high precision. [0003] The basic idea of ​​the structured light 3D measurement method is to use the geometric relationship of the structured light projection to obtain the 3D information of the object. First, the coded struc...
