The process of fitting treatment equipment is for receiving the instant full color image, based on marginal point tonal range from described immediately full-color
Multiple edge pixel points are extracted in image, and the multiple edge pixel point is fitted, to obtain multiple edge lines, and is based on
The signal-to-noise ratio of the instant full color image carries out uniform formula division to the instant full color image, to obtain multiple subgraphs；?
In the process of fitting treatment equipment, multiple edge pixel point packets are extracted from the instant full color image based on marginal point tonal range
It includes: for each of instant full color image pixel, determining whether its gray value falls in the marginal point gray scale model
In enclosing, when falling in the marginal point tonal range, determines that the pixel is edge pixel point, be non-edge pixels point otherwise.
6. foam as claimed in claim 5 detects alarm mechanism, it is characterised in that:
The Threshold Analysis equipment is connect with the process of fitting treatment equipment, for receiving the multiple subgraph, and is measured each
Edge line quantity is more than each subgraph of preset quantity threshold value as each reference by the edge line quantity in a subgraph
Image.
7. foam as claimed in claim 6 detects alarm mechanism, it is characterised in that:
The contrast lifting means is connect with the Threshold Analysis equipment, for receive it is described each with reference to subgraph, it is right
It is described each with reference to subgraph execute contrast promotion processing, with subgraph after being promoted.
8. foam as claimed in claim 7 detects alarm mechanism, it is characterised in that:
The Analysis signal-to-noise ratio (SNR) equipment is connect with the contrast lifting means, for receiving subgraph after each is promoted, and
When the signal-to-noise ratio of subgraph is less than preset ratio threshold value after the lifting, executes and the gaussian filtering of subgraph after promotion is operated,
Corresponding gaussian filtering subgraph is obtained, and exports each gaussian filtering subgraph, and by each gaussian filtering subgraph
Image after integration replaces the instant full color image and is sent to the region segmentation equipment.
9. foam as claimed in claim 8 detects alarm mechanism, it is characterised in that:
Different MCU chips is respectively adopted to realize in the process of fitting treatment equipment and the Threshold Analysis equipment.
10. foam as claimed in claim 9 detects alarm mechanism, it is characterised in that:
In the process of fitting treatment equipment, the process of fitting treatment equipment is defeated by image receiving unit, image processing unit and image
Unit forms out, and described image processing unit is connect with described image receiving unit and described image output unit respectively.
