The high precision vision detection system includes the digital staff guage system, the illuminating system with adaptive adjusting optical intensity, the auto focus system, the optical image system, the vision detection software, the foundation, the computer or microprocessor system. The digital staff guage system is used to provide the high precision length detection base in large scale; the illuminating system is used to adjust the optical intensity according to the different of the detection distance, detection angle and the surface reflectivity of detected workpiece to provide the uniform and stable illuminating intensity to pledge the image quality and the detection precision; the auto focus system is used to adjust the working distance of the detection system to pledge the image has the good quality and constant amplification ratio and pledge the repeatability and detection precision of the detection system; the optical image system is the main part of the detection system, which is used to transform the geometry outlook of detected workpiece to the computer or processor through the optical lens image, the vidicon photoelectricity switch and collecting control circuit; the vision detection software is used to process the image and get the detection result; the foundation is the supporting frame of vision detection system, which is used to fix, support and move every part of system; the computer or microprocessor system is the core part of the whole vision detection system, which is used to coordinate and control every system.

The invention discloses a user grouping method, which includes: determining one or more exclusive attributes of the category according to the browsing behavior of users who have purchased commodities under the category within the first predetermined browsing time range; Traversing and combining each product attribute value with each product attribute value with other exclusive attributes to obtain the user group corresponding to each combination; the users who have the willingness to purchase products under this category within the second predetermined browsing time range Users are assigned to corresponding user groups. The exclusive attribute is a commodity attribute with multiple commodity attribute values, and the multiple commodity attribute values ​​completely cover all commodities under the category; the same commodity attribute selected by the same user group in the process of browsing commodities under the category The product attribute value of is the most concentrated, and has a low degree of overlap with other product attribute values ​​of this product attribute. By adopting the present invention, user groups can be distinguished according to the real purchase needs of users.
