Abstract

The invention is a domain uniqueness-based method for realizing high efficiency structural light, producing a high efficiency coding phototemplate for a light projector in the structural light system and using the phototemplate for 3D reconstruction and comprising the steps of: (1) selecting different colors to compose a code set; (2) selecting elements from the code set, expressing each optical lattice by one color, making special code combination to produce the phototemplate and composing adjacent optical lattices into a coded word, which has the domain uniqueness; (3) corresponding the coded words to input and output beams of the light projector one to one; (4) corresponding the obtained image to the phototemplate to calculate the 3D coordinates. And a device for realizing the high efficiency structural light comprises light projector, vidicon and microprocessor, where the microprocessor comprises color set module, coding module, code word decoding module and 3D coordinates calculating module. The invention has high 3D sensing speed, high reconstructing efficiency and low use cost.

Description

(1) Technical field [0001] The invention relates to a three-dimensional measurement method based on computer vision, a mathematical space coding method and a device thereof. This method is mainly used for surface reconstruction of three-dimensional objects, and has a wide range of applications, typically including workpiece detection in the manufacturing industry, scene depth perception, reverse engineering, object recognition, etc. (2) Background technology [0002] In computer vision-based 3D perception technology, binocular stereovision (stereovision) is a common method, which obtains scene images from two or more viewpoints and establishes a point-to-point matching relationship to determine 3D position parameters. This triangulation method is feasible (albeit with certain accuracy and reliability limitations) if the cameras have been calibrated beforehand. However, the correct matching between such image points is actually very difficult when considering the epipolar co...
