Problems solved by technology

Another problem brought about by the huge amount of data is that it is very inconvenient to look back at the data, and it is difficult to quickly locate events in the video stream
In addition, most of the video data collected by the probe is invalid data, such as unmanned scenes, but these data occupy a large amount of storage space, causing unnecessary waste

Embodiment 1

[0157] Image acquisition device 1 adopts a camera based on 1 / 3″ SONY vertical double-density interline CCD, its scanning method is 2:1 interlaced scanning, the resolution is 560 lines in color mode, 600 lines in black and white enhanced mode, NTSC standard The effective pixel is 768×494, and the effective pixel is 752×582 under the PAL system.

[0158] The image front-end processing device 2 is a printed circuit board welded by using Texas Instruments TMS320DM8147 Da Vinci digital media processor as the main chip and adding corresponding peripheral equipment. The digital media processor integrates a C674x DSP with a maximum frequency of 750MHz and an ARM Cortex-A8 processor with a maximum frequency of 1000MHz. The digital media processor is designed to support single-channel 1080P encoding, or three-channel 720P encoding. Because the DSP of this digital media processor is used here to realize all the functions of the whole picture comparison unit 21, and undertake the work su...

Abstract

The invention discloses a real-time image processing system which comprises an image collecting device, an image front end processing device, a data transmitting device and a background system. The image collecting device is used for processing images by using a real-time image processing method after collecting images; the image front end processing device is used for carrying out full image comparison, carrying out key area comparison if a threshold value A is exceeded and delivering images and relevant data to a rear end controlling / processing device through the data transmitting device if a threshold value B is exceeded; and the rear end controlling / processing device is used for carrying out operations such as separating, verifying, deciphering, and the like on the data, and then delivering the data to a rear end data storing device to store. The functions of automatically detecting the state change of a monitoring area, automatically eliminating invalid data and intelligently shooting are realized by the system. The hardware cost and the total cost of the system are reduced.

Description

technical field [0001] The invention relates to a real-time image processing system and a real-time image processing method based on the system. [0002] Background technique [0003] The inspection and testing work of various laboratories is very important to ensure the safety and reliability of various products.
