Abstract

The invention discloses a binocular camera distortion correction system and method based on an FPGA, and an intelligent terminal. The system comprises an image caching module which is used for receiving a left image and a right image collected by a binocular camera, and caching the data of the left image and the data of the right image; the distortion correction module is used for reading the correction table data and decomposing the correction table data into storage addresses; and reading and caching the data of the left image and the data of the right image, reading an image data matrix according to a storage address of table data decomposition, and substituting the image data matrix into a bilinear interpolation module to perform bilinear interpolation calculation, thereby outputting aleft image correction image and a right image correction image. The technical problem that in the prior art, a camera distortion system occupies a large amount of memory and system resources, and consequently the overall performance of the system is poor is effectively solved.

Description

technical field [0001] The invention relates to the technical field of camera distortion correction, in particular to an FPGA-based binocular camera distortion correction system, method and terminal equipment. Background technique [0002] For the technical field of camera distortion correction, the embedded processor is usually used for correction. This correction method is to read out the corresponding 2×2 data matrix of the original image from the memory point by point according to the correction table output after calibration. Perform bilinear interpolation. However, traditional camera distortion correction methods will occupy a large amount of memory and system resources, thereby reducing the overall performance of the system. Contents of the invention [0003] To this end, the embodiments of the present invention provide an FPGA-based binocular camera distortion correction system, method, and terminal equipment to at least partially solve the overall system performa...
