摘　　要：开发了一种基于计算机视觉的轮胎负荷轮廓测量系统。测量系统由CMOS摄像机、激光传感器、光栅尺和控制器等组成。通过轮胎胎侧轮廓的三维空间坐标,精确重构轮胎负荷胎侧轮廓,并实现了其几何参数快速测量,系统的测量精度可达±0.1 mm。与传统的机械手工测量方法相比,该系统具有非接触、无磨损和高效率的优点。A measurement system for tire profile under load was developed based on computer vision technology. The measurement system consisted of CMOS cameras,laser sensors,grating rulers and control box. By using the 3D space coordinate of sidewall profile,the sidewall profile of the tire under load was precisely reconstructed,and a fast measurement of geometric parameters of tire profile was achieved. The measurement accuracy of the system was ±0. 1 mm. Compared with traditional artificial measurement,this system showed advantages of non-contact,non-abrasive and high-efficiency.
