Real-time processing method and system for batch image data

Abstract

The invention relates to a real-time processing method and system for batch image data. The method comprises the following steps of: performing signal conversion on data transmitted by an industrial filed to obtain valid signals of frames and rows, pixel clocks and 24-bit parallel image data, wherein four pixel points in the image data of each row form a group; latching four pixel point data of pixels of each group by using four 24-bit latches; and latching 96-bit valid data in the four 24-bit latches by using three 32-bit latches, transmitting the data to three 32-bit buffers for caching, uploading the data to the left port of a 32-bit double-port SRAM (Static Random Access Memory), reading the data of the whole row from the right port of the SRAM by an embedded controller, storing the data in a 32-bit SDRAM (Synchronous Dynamic Random Access Memory) to form a frame of image data, and processing the image data. The 24-bit data of the pixel points are recombined through a hardware circuit, so that the increment of 8-bit higher redundant data in the 32-bit memory is avoided, the data processing quantity of the image of each frame is reduced, the batch image processing efficiency is greatly improved, and real-time processing of the batch image data is realized.

Description

technical field [0001] The invention belongs to the field of industrial control, and relates to a method and system for real-time processing of large batches of serial high-speed image data generated on industrial sites. Background technique [0002] In the cotton foreign fiber sorting machine, the main controller needs to transmit the entire frame of data to the host computer at the same time while processing a large amount of cotton image data in real time, so as to adjust the parameters of the image equipment and monitor the operating status. However, at present, the foreign fiber sorting machine starts to use the embedded controller as the main controller. Unfortunately, it is difficult for many embedded controllers to perform real-time processing and network transmission after receiving each frame of image data. This is mainly due to the following reasons: First, the embedded main controller mainly uses the time between frames for data processing and network transmissi...
