CF cards, for having prestored reference mark image, reference mark image is the original image of test pattern mark；
Freescale MC9S12 chips, connect, be used for landmark identification equipment, position sensor, servomotor and CF cards respectively
The first bed board height and the second bed board height are received, based on the first elevation weight value, the first bed board height, the second elevation weight value
Current bed board height is highly determined with the second bed board, and when current bed board is highly more than or equal to preset height higher limit, is sent
Bed board crosses high RST, when current bed board is highly less than or equal to preset height lower limit, sends bed board and crosses low signal；
Wherein, for test pattern traffic sign placement below bed board, test pattern mark is shaped as triangle, square or circle；
Wherein, landmark identification equipment carries out the pixel sum of the pixel sum indicated in subgraph and reference mark image
Compare highly is included with determining and exporting the first bed board：Indicate the picture of the pixel sum divided by reference mark image in subgraph
The numerical value that vegetarian refreshments sum obtains is bigger, and the numerical value of the first bed board height is smaller, indicates pixel sum divided by base in subgraph
The numerical value that the pixel sum of quasi- sign image obtains is smaller, and the numerical value of the first bed board height is bigger；
Wherein, module selects filtration module selective in sub- equipment to include 3 × 3,5 × 5,7 × 7 and 9 × 9；
Wherein, CF cards have also prestored default bed board height, the first elevation weight value, the second elevation weight value, preset height
Higher limit and preset height lower limit；
Wherein, CF cards are also connected with landmark identification equipment, servomotor and Freescale MC9S12 chips respectively；
Wherein, CF cards are additionally operable to prestore each benchmark human body image, and each benchmark human body image is to the different bodily forms
The image that benchmark human body is shot and obtained in advance；
Wherein, module, which selects sub- equipment to carry out the filtration module of medium filtering based on maximum distribution radius selection, includes：Maximum point
Cloth radius is bigger, and the filtration module of the progress medium filtering of selection is bigger, and maximum distribution radius is smaller, the carry out intermediate value filter of selection
The filtration module of ripple is smaller；
Module selects sub- equipment to be realized using CPLD chips.
