The screening conditions comprise a chromatic aberration value range, ash removal time length and ash removal frequency, and the equipment operation parameters comprise the sensitivity of a lens, the light intensity of a light supplement light source of the lens, the sampling frequency of the lens and sampling time.
The sensitivity setting subunit 41 is configured to acquire a sensitivity parameter, and output an operation instruction for adjusting the sensitivity of the corresponding lens and the color difference value range according to the sensitivity parameter. The sensitivity of the lens is the acquisition resolution of the lens, and if the resolution of a captured image acquired by the CCD camera is higher, the resolution of the pixel points of the synthesized surface model is higher. And the color difference value range indicates that the material is qualified if the color difference value between the pixel point of the current material surface model and the pixel point of the normal or qualified material surface model is in the value range. Therefore, the acquisition resolution affects the accuracy of image recognition, and the chromatic aberration value range is adjusted according to the quality requirement of a user.
The material may have defects and the equipment may have errors, so the sensitivity may also indicate the fault tolerance of the equipment. And when the color difference value between the surface color of the material and the normal color of the material is in the color difference value range, the material is qualified, wherein the larger the color difference value range is, the higher the fault tolerance rate is, and the lower the sensitivity is, and conversely, the smaller the color difference value set range is, the higher the sensitivity is.

The ash removal process can be realized by a high-pressure air gun and an electromagnetic valve, and the electromagnetic valve is controlled to be opened and closed by an ash removal instruction, so that the aims of adjusting the ash removal time and the ash removal frequency are fulfilled.
The camera lens need provide solitary illumination environment at the in-process of shooing the material to this reduces the influence that outside light changes image recognition, consequently need use the light filling light source. The supplementary lighting setting subunit 43 is configured to obtain the illumination parameter, and adjust the light intensity of the supplementary lighting source of the lens according to the illumination parameter. Can adjust the luminous intensity that is fit for current material with ambient light through light filling setting subunit 43 to influence the true degree of color reduction, reduce the identification error, with this convenient illumination intensity according to the material needs carries out adaptability and adjusts, improves the screening precision.
The flow setting subunit 44 is configured to obtain a flow parameter, calculate a sampling frequency and a sampling time of the material surface model, and output a control instruction for controlling the sampling frequency and the sampling time. The flow rate is the speed of material transmission, and the speed can influence the stay time of each material on a station and the sampling frequency of a CCD lens for acquiring a material surface model. The sampling frequency and the sampling time of the CCD lens can be conveniently calculated through the flow of input materials, so that the stability and the accuracy of data sources such as a surface model and the like are improved. For example, the material moves once every 3s, the moving time is 1s, the lens is shot once every 1s, and the shooting time is selected within 3s, so that the transportation rhythm of the lens matched with the assembly line is controlled, and the phenomena of missed shooting and image blurring are reduced.

The screening unit 2 is used for obtaining the standard model template and the screening conditions, and executing the material screening process according to the standard model template and the screening conditions. The screening condition has a plurality of items, and comprises a shape selection condition and a spot display condition besides a color difference value range, and the screening unit 2 comprises a shape selection subunit 21 and a spot selection subunit 22. The screening unit 2 screens the materials based on various screening conditions, and the screening conditions can be combined or screened separately, for example, when the materials meet a certain screening condition, the next screening process is performed, then screening is performed according to another screening condition, and the materials which do not meet the screening condition are separated step by step. In another embodiment, the materials are qualified only if they simultaneously satisfy a plurality of screening conditions, the materials that do not satisfy any of the set screening conditions are separated, and the screening conditions can be combined according to the user's requirements.
The shape selecting subunit 21 corresponds to shape selecting conditions, and is configured to obtain and select a qualified material surface model according to the shape selecting conditions, where the shape selecting conditions are the number of bad points of the material surface model, that is, if the number of bad points of the current material exceeds a set threshold, it is determined that the material is unqualified. In short, the shape selecting subunit 21 is configured to collect the number of bad points on the surface model of the material, determine the quality of the material based on the number of bad points, and determine that the material is unqualified if the number of bad points of the current material exceeds a set threshold.
Because the surface model of the material is composed of pixel points, the determination of the dead pixel can be judged by an RGB value or a gray value. For example, when the gray value is used for judging, if the gray value range of the normal pixel point of the surface model of the qualified material is not lower than a, the gray value of a certain pixel point of the material is lower than a, and then the material is judged to be a dead pixel. And the quantity of the pixel points formed by the surface models of different materials is possibly different, so that the screening can also be carried out in a dead pixel proportion mode, for example, if the ratio of the dead pixel number of the material to the total pixel number of the surface model exceeds a set ratio, the material is judged to be unqualified.
The spot is a closed area which is formed by pixel points with the same color or the same gray value, the color or the gray value is different from the normal color or the gray value of the material, and the spot display condition is that whether the converted value of the spot obtained by calculating the area of the area occupied by the spot, the number occupied by the spot or the area and the number occupied by the spot through a weighting algorithm exceeds a set value. The blob selection subunit 22 is enabled when the screening condition adopts the blob display condition, and the blob selection subunit 22 is used to obtain the area and the number of blobs. And if the area of the area occupied by the spots exceeds the set area or the number of the spots exceeds the set value, judging that the material is unqualified. In another embodiment, the spot display condition may also include two parameters of the area occupied by the spot and the number occupied by the spot, that is, if the converted value of the spot calculated by the weighting algorithm exceeds the set value, the material is determined to be unqualified.
