车辆轮对作为重要的可互换走行部件,对列车安全行驶起着关键性的作用。目前,我国列车轮对的参数检测基本还停留在手工测量阶段,技术落后、工作效率低。用数码相机采集图像,结合计算机数字图像处理技术,基本能获得我们所需轮对各检测参数,并使测量精度满足检测标准要求。 Vehicle wheel pair as an important interchangeable walking parts, the safe driving train plays a key role. At present, the parameter testing of train wheels in our country basically stays in the stage of manual measurement, with backward technology and low work efficiency. With digital cameras to capture images, combined with computer digital image processing technology, we can basically get the required test parameters of the wheel, and the measurement accuracy to meet the testing standards.
