2023/04/25Tire is an important part of the automobile, its manufacturing process is complex, in the whole manufacturing process, there are strict quality requirements. In addition to fine appearance detection, a small number of tires will have some defects; such as unqualified size, scratches, bulge, etc.; in some processes, tire pattern detection and DOT character identification, which require 3D visual intervention to overcome many disadvantages of manual detection, and improve its accuracy and work efficiency.
Today for you to introduce the next vision tech LVM 2040 camera in the tire industry 3D vision application case! LVM 2040 Line laser 3D camera model is comprehensive, meet the requirements of various high-speed and mass detection applications; can provide 340Hz full frame acquisition rate, physical contour points 2048 points, depth map uniform spacing sampling maximum 4096 points; Gigabit Ethernet transmission, meet the requirements of multiple scenarios.
一、Ttread section size testing
Customer requirements: measure the tread thickness outline, total width, shoulder width, medium width, shoulder thickness, medium thickness and other key dimensions, keep abreast of the change of tread size at any time, and control the product quality
Product model number: LVM2040
Application challenge: many types of tire material, material surface state difference
High-precision and large-format detection requires multi-camera splicing
Need to customize the camera view and Angle
