8. the two-dimensional code scanning system according to claim 6 based on background color identification, which is characterized in that further include scanning rule
Then setting device, comprising:
Scheme composite module, the light source parameters for photographic parameter and secondary light source to camera connect within a preset range
Continuous value obtains multiple testing programs, and multiple testing programs of the multiple testing programs and light source parameters to camera parameter carry out
Combination forms multiple sweeping schemes；
As a result module is obtained, is taken multiple scan for obtaining according to image in 2 D code of multiple sweeping schemes to different background colors
To multiple recognition result；
As a result screening module is best suitable for identification in the multiple recognition result of the image in 2 D code for obtaining each background color and sentences
Sweeping scheme corresponding to the recognition result of set pattern then；
Setting module, for the sweeping scheme to be set as to the output set information of corresponding background color.
9. the two-dimensional code scanning system according to claim 8 based on background color identification, which is characterized in that the identification decision
Rule are as follows: recognition time is shortest and/or the highest recognition result of discrimination is to meet item.
10. the two-dimensional code scanning system according to claim 8 based on background color identification, which is characterized in that the scanning rule
Then include:
When the background color is yellow, red, green or when black, the camera interior lighting is closed, and the time for exposure is
510 μ s, the secondary light source are opened, photochromic for blue；
When the background color is blue, the camera interior lighting is opened, and the time for exposure is 455 μ s, the fill-in light
Source is closed.
