Embodiment 3

[0093] In double-lane license plate recognition:

[0094] In high-performance vehicle real-time monitoring systems, technology applications based on high-speed imaging are becoming more and more common. For the monitoring of two lanes, a single image sensor system can be used. In order to realize the real-time processing of a large amount of image data, two computers are used to process the image information of the left and right lanes respectively. The image acquisition module divides the image into two parts, and each part covers a lane respectively. Among them, both parts include the part where the two lanes meet. Then the images of the left and right lanes are sent to the two processors respectively. In this way, difficulties in license plate recognition can be avoided when the vehicle crosses the lane. Such as Figure 4 As shown in , the position of the license plate of the vehicle crossing the line is exactly in the middle of the original image. If the image is simp...

Description

technical field [0001] The invention relates to an image processing device and method, in particular to a high-speed image acquisition and processing method and device. Background technique [0002] Machine vision is more and more widely used in the field of high-speed, real-time feature text and feature symbol recognition. Existing embedded machine vision systems generally consist of an image sensor and a processor. The processor is used to acquire and process the images generated by the image sensor. Some systems can consist of multiple image sensors and a processor. The processor can selectively select images from one of the image sensors for processing. [0003] In high-speed image acquisition and processing systems, the speed of the image sensor is very fast, and usually a processor cannot complete real-time image processing. The existing method is to store the image in the memory first, and then send the image to the processor for processing at a relatively slow sp...
