Depth information detector, time-of-flight camera, and depth image acquisition method

Abstract

A depth information detector includes a light receiving module and a processor. The light receiving module includes a first receiver and a second receiver set at intervals. The first receiver and the second receiver receive a reflected light reflected by an object to be detected at different positions respectively. The processor electrically connects to the light receiving module. The processor is configured for synthesizing the reflected light received by the first receiver and the second receiver into a depth image. The light receiving module also includes a first polarizer and a second polarizer, the first polarizer is on one side of the first receiver, the second polarizer is on one side of the second receiver, a polarization direction of the first polarizer and a polarization direction of the second polarizer are orthogonal to each other. A time-of-flight camera and a depth image acquisition method are further disclosed.
