螺旋锥齿轮齿面点图像识别及其测量技术

利用计算机视觉测量系统对螺旋锥齿轮的加工进行测量,尝试了一种新的具有较高测量精度和测量效率的非接触测量方法。通过利用两个固定的摄像机对齿轮加工进行检测,然后对摄像机拍摄到的图像进行三维重建,从而可在计算机中得到螺旋锥齿轮的齿面坐标,再通过与理论齿面进行比较,可以得到加工齿面的误差,从而对加工参数进行修正。这大大简化了螺旋锥齿轮检测和修正的工序,为实现螺旋锥齿轮加工、检测、调整闭环系统提供了技术支持。

On Point Image Recognition and Measurement of a Spiral Bevel Gear's Tooth Surface

We use the computer vision measurement system to measure the surface points of a spiral bevel gear. This is a new non-contact measurement technique with high precision and efficiency. We use two fixed cameras to measure the processing of the gear and then carry out 3D reconstruction of the images produced by the cameras. Thus we obtain the computerized coordinates of the surface of the spiral bevel gear. Its comparison with the theoretical gear surface produces the deviations of the processed gear surface. In this way, we can modify the processing parameters. This greatly simplifies the processes of measurement and modification of a spiral bevel gear and provides technical support for the loop system of machining, detection and adjustment of the spiral bevel gear.
