Abstract

The invention relates to a low-cost three-dimensional laser scanner. Laser and a CMOS (complementary metal oxide semiconductor) camera are combined for scanning an actual scene, image processing is performed, and a three-dimensional coordinate message is calculated. As is shown in an abstract attached picture, an MSP430 microprocessor is taken as a control mechanism, a line laser on a rotation table is used for projecting line laser to a to-be-detected scene or object, the CMOS camera provided with an optical filter is used for shooting the scene, the image processing is performed after a PC terminal acquires a shot picture, data are calculated, and a three-dimensional point cloud is obtained, so that three-dimensional space is scanned and reconstructed, and the computer is cognized.

Description

(1) Technical field

[0001] The invention is a low-cost three-dimensional laser scanner. The device uses a laser combined with a CMOS (ComplementaryMetalOxideSemiconductor, which refers to a complementary MOS integrated circuit manufacturing process composed of complementary metal oxides (PMOS tube and NMOS tube)) camera to scan the actual scene and calculate the three-dimensional coordinate information through image processing. It involves hardware drive and control technology, image processing technology, data calculation algorithm, etc., and the cost of the device is low, and the control technology is relatively simple. It is suitable for spatial scanning reconstruction and achieves the purpose of computer cognition. (2) Background technology
