The processing of scene image just can obtain the m fisrt feature pattern coated on m the first blocks in the M the first blocks.And
Based on identifying to m fisrt feature pattern, terminal device, which determines, itself can identify the m fisrt feature pattern, therefore press
According to preset control program, what terminal device can determine that m first area constitute can be on identified first area
The material placed is fallen.
It should be noted that if terminal device determines after having material to fall on conveyer belt, but terminal device is based on to acquisition
Material conveying scene image processing, determine that the first area on conveyer belt can not be still identified, then illustrate object at this time
Material is still placed on first area.Therefore, having material to fall on identified conveyer belt may block for people or other objects
N second feature pattern on second area is lived.Therefore terminal device can be confirmed as erroneous judgement, just not do alarm prompt, and
Terminate the execution of subsequent step S200 and step S300.
Step S200: the area information of the first area is obtained.
Due to pre-setting the block information of each first block in terminal device, then determining first area institute
After m the first blocks for including, terminal device can also obtain the m corresponding m block informations of the first block accordingly.The m
