基于改进型SUSAN算子四轮定位参数检测方法实现

The Test Method of Wheel Alignment Parameters Based on Improved SUSAN Operator

针对当前四轮定位仪传感器众多、精度低、操作复杂、维护成本高等缺点,提出一种三维视觉式四轮定位参数检测的新方法,阐述了基于改进型SUSAN算子实现该方法,通过采集随车轮一起运动的棋盘格式目标盘的序列图像,求取车轮旋转轴线的三维方向余弦,进而求得四轮定位几何参数。与传统方法相比具有非接触、实时、操作简便、精度高的优点。

In view of the current four-wheel sensors＇ shortcomings, such as large amount, low accuracy, complex operation, and high maintenance costs, etc. we put forward a new method of detection which uses three-dimensional visual to detect parameters of four-wheel location. This paper expounds the improved SUSAN operator which is based on the proposed method. Through the collection of sequence image of the target disk format board which moves together with the wheels, we calculate three-dimensional cosine of the rotation axis of the wheels, then get four-wheel location geometric parameters. Compared with the traditional methods, this new method has many advantages, such as non-contact, real-time, simple operation, high precision and so on.
