Problems solved by technology
However, not all algorithms can be executed in parallel internally. These algorithms can only use one CPU core at runtime, and process all pixels in a traversal manner.
In addition, in some algorithms, each pixel needs to be averaged with several pixels around the pixel, and it is easy to form a discontinuous boundary at the boundary when the block is calculated in parallel.
In order to solve the discontinuity phenomenon, the block image needs to overlap several widths or heights, which means that the calculation is repeated at the boundary, and then the overlapping part is discarded when merging to eliminate or reduce the boundary phenomenon, which brings the calculation Expansion of resources and complexity of final synthesis

The present invention provides a parallel image processing method. The method comprises a step of collecting image data at a certain time, a step of scheduling the image data to a standby processing thread, a step of allowing the processing thread to call an algorithm in sequence according to an order to process and display the image data, a step of collecting image data at a next time, a step ofscheduling the image data to a next standby processing thread, a step of allowing the processing thread to call the algorithm in sequence according to an order to process and display the image data, and a step of repeating the above steps until the execution of the algorithm of a first processing thread is completed and displaying a final image.
Description
technical field [0001] The invention provides a parallel image processing method and system. Background technique [0002] In the process of image processing, the collected raw image data is generally processed to eliminate noise, improve contrast, or extract key signals to meet specific applications in different industries. Each processing process can be called an algorithm, and generally multiple algorithms are executed sequentially to generate a final image for display. [0003] Assume that the time consumption of algorithm A is TA, the time consumption of algorithm B is TB, the time consumption of algorithm C is TC, the time points of collection are t1, t2, t3, etc., and the average time interval of collecting an image is T, then the system The acquisition frame rate is 1 / T. Then, if the final image is to be displayed at the speed of image acquisition, the total time spent on image processing is required to be TA+TB+TC≤T. In other words, the "display frame rate" canno...
