The process that video processor carries out image optimization is:
1) extracts R, the G of each two field picture in the video, the channel data of B passage, and low frequency threshold value and the high frequency threshold value of each passage are set according to channel data;
2) the low frequency threshold value corresponding with it and high frequency threshold ratio obtain respectively low frequency component and high fdrequency component respectively with the channel data of R, the G of image, three kinds of passages of B;
3) the intensification modulation mode in conjunction with gray scale morphology computing and human eye strengthens high fdrequency component, and color, the saturation degree of low frequency component are adjusted;
4) treated high fdrequency component and low frequency component are synthesized a frame image data again.
Intensification modulation mode in conjunction with gray scale morphology computing and human eye to the detailed process that high fdrequency component strengthens is:
A) high fdrequency component of original image is carried out morphologic opening operation, deduct again the high fdrequency component of original image, obtain relative peak;
B) deduct the high fdrequency component of the original image after the morphologic closed operation with the high fdrequency component of original image, obtain relative valley;
C) high fdrequency component of original image adds relative peak, deducts relative valley again.
Compared with prior art, the present invention extend into the inside of GIS equipment by the camera that is positioned at the telescopic arm front end, by kink and universal wheel are set, and can be movable flexibly at the GIS device interior, make things convenient for camera to obtain the image of each narrow and small position, the efficient that can Effective Raise detects; Can be optimized it by video processor for the image that obtains, obtain more clearly image, improve the accuracy that detects.
