When optical filter mould group and object under test inverse, camera carries out the color that image recognition reads object under test figure, passes through After background process, energy coefficient corresponding to the energy consumption of detector is A₂；

When camera identifies the unit area of object under test, energy coefficient corresponding to the energy consumption of detector is B；

When optical filter mould group and object under test are homochromy, constant is set as C₁；

When optical filter mould group and object under test inverse, constant is set as C₂；

According to one: ∫ A of formula₁B-C₁=D₁；With two: ∫ A of formula₂B-C₂=D₂；

Finally obtain numerical value D₁And D₂As a result, and by judging the numerical value whether in the acceptability limit of color difference from the background.

Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages:

This programme replaces traditional color difference meter in the form of camera cooperates optical filter mould group, and optical filter mould group is using mechanical knot Structure is set to the front side of camera, and the influence of external light source is eliminated by optical filter mould group, camera is allow to be placed in opening In the detection space of formula, area of detection is greatly improved, according to different cameras is used, area can be will test and be increased to 10 Square metre or it is bigger, be the essential breakthrough that color difference examines field；In conjunction with the detection method of this programme, can greatly improve Detection efficiency and accuracy.

Detailed description of the invention

Technical scheme of the present invention is further explained with reference to the accompanying drawing:

Attached drawing 1 is a kind of schematic diagram of acetes chinensis mechanism of the present invention.

Specific embodiment
