Abstract

The invention provides a device and system for capturing a stereoscopic image. The device for capturing the stereoscopic image comprises a time of flight image capturing module and a light emitting module. The light emitting module generates a structural light source and an illumination light source. The time of flight image capturing module captures first and second reflection light sources formed by projecting the structural light source and the illumination light source onto an object, so as to acquire the stereoscopic image information of the object. According to the invention, by integrating time of flight (TOF) and structured light technologies, the stereoscopic image information with high depth accuracy and low noise is acquired, and the overall volume and use power of the device and system are reduced.

Description

technical field [0001] The invention relates to a device and system for capturing image information, in particular to a device and system for capturing stereoscopic images. Background technique [0002] Stereo scanning technology has been widely used in industrial fields and daily life, such as in stereo scanning, surveillance identification, and depth cameras. Stereo scanning technology is mainly used to detect and analyze the geometric structure and appearance data of objects or environments, and use the detected data to perform three-dimensional calculations, and then simulate and establish digital models of objects and environments. [0003] Existing 3D scanning technologies include the use of time of flight (TOF), stereo vision (Stereo Vision) or structured light (Structured Light) technologies to capture and calculate 3D image data. In the aforementioned three-dimensional scanning technology, the time-of-flight method calculates the distance between the object under t...
