Abstract
Targeting the real time and precision of multi-target center location in FPGA image processing,a pipelined connected domain fast labeling and center location algorithm is proposed.Through a single raster scan of the image,the run information of each row is cal-culated and the connected runs are counted.When the number of rows reaches a certain value,the marked runs are traversed,the gray values are counted,and the gray values of subsequent connected pixels are added.When it is determined that there are no adjacent runs in the next row,the mark center is solved and output.The experimental results show that the final precision of the algorithm is controlled within 0.1 pixels,and the processing time of the algorithm is reduced by 18.1%compared with the conventional algorithm.With this al-gorithm as the core,a set of ZYNQ multi-marker center real-time positioning system is designed,which realizes the functions of binocu-lar camera acquisition,image preprocessing,connected domain labeling and positioning of multi-marker center coordinates,etc.The sta-bility of the proposed algorithm in the real environment is verified,and it has certain application value in the field of image sensor real-time processing.关键词
