Spatial positioning system and positioning method

Abstract

The invention provides a space positioning system and a positioning method, the space positioning system comprises a first image acquisition module, a second image acquisition module, an FPGA chip and a GPU chip, the first image acquisition module and the second image acquisition module acquire two images from different directions, the FPGA chip is used to carry out image preprocessing on the two images, and the GPU chip is used to carry out image processing on the two images. And then the GPU chip is utilized to carry out stereo matching based on the two preprocessed images to obtain required coordinate information, that is, an image preprocessing algorithm is solidified in the FPGA chip, and a positioning algorithm is solidified in the GPU chip, so that the size requirement and power consumption of hardware equipment are greatly reduced, and the system has the characteristics of flexible application, small size and low power consumption, and is high in computing power, high in output frame rate and high in reliability. And the positioning result is directly output, is plug-and-play, and is very conveniently integrated into other intelligent equipment, so that the problems of poor robustness, low calculation speed, large size and high power consumption of a traditional visual system are effectively solved.
