非接触式轮对自动测量新方法利用先进的结构光视觉传感技术完成轮对各参数的测量。通过结构光扫描轮对,在轮对不同的部位产生相应的变形光,利用视觉传感及图像处理等技术提取结构光变形曲线,获取轮对几何信息,实现轮对外形尺寸、轮对踏面擦伤和剥离等多个参数的在线非接触测量。该方法简单、可靠,测量精度为±0 2mm。
The new method of automatic measurement of non-contact wheelset utilizes the advanced structured light vision sensing technology to measure the parameters of the wheelsets. Through structured light scanning wheel pairs, the corresponding deformation light is generated in different parts of the wheel pair, the deformation curve of the structure light is extracted by the technologies of visual sensing and image processing, the geometric information of the wheel pairs is obtained, the wheelset outer dimensions, the wheel tread rubs Injury and stripping and other parameters of the online non-contact measurement. The method is simple and reliable, the measurement accuracy of ± 0 2mm.
