Embodiment Construction

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and the embodiments of the present invention.

[0050] figure 1 It is a schematic diagram of the logic flow of the producer-consumer model in the embodiment of the present invention.

[0051] Such as figure 1 As shown, in the producer-consumer model, the thread that receives the camera image is set as the producer, which is only used to store the image. If the follow-up action time is too slow, it can also selectively discard some unimportant images. ;The subsequent image processing thread acts as a consumer. It gets image data from the producer and performs a series of image processing. It does not care about the frequency of the camera, but only cares about its own processing speed.

[0052] To remove the traditional strong coupling relationship between producers and consumers, a concurrent queue is needed as an intermediary.

[0053] The concurrent queue h...

Abstract

The invention discloses a high-speed camera image sequence processing method and processing system, and the method comprises the steps: A, starting a high-speed camera for image collection, and creating a producer thread and a consumer thread; b, controlling a producer thread to obtain image data, and pressing the image data into a concurrent queue; and C, controlling the consumer thread to perform image transformation, and displaying the transformed image. By adopting the method and the system, the image sequence can be processed under the high image transmission frame frequency, the strong coupling between the modules can be removed, and the multi-core resources of the CPU can be fully utilized, so that the parallel processing between the processing modules can be realized, and meanwhile, the further optimization and improvement in each program module are facilitated.

Description

technical field [0001] The invention relates to computer image processing technology, in particular to a processing method and a processing system of a high-speed camera image sequence. Background technique [0002] High-speed image sequence specifically refers to the image sequence transmitted from the camera to the image processing system (such as a computer) at 100-500 frames per second (fps). At this time, the processing time for each frame from image reception to display is only about 2-10ms . [0003] In such a length of time, the time spent on image caching and display accounts for a large part, and the time for image processing cannot be far behind the time for other operations. However, the factor that causes image data loss is only the data cache time. Too long time to save from the camera buffer to the memory will cause image loss, and the time for subsequent operations does not need to be concerned. [0004] In the same way, the image processing module should n...
