An evaluation method for the radius of curvature parameters of non-holonomic small arcs

Aiming at the difficulty of current non-holonomic small arcs in the evaluation technology of curvature radius parameters,the trend of the influence of the small arc parameters on the evaluation process was analyzed by simulation.According to the comparative analysis of the evaluation results of several existing evaluation algorithms.An algorithm that combines the least squares method and the Hough transform method is applied to the evaluation of the radius of curvature parameters of non-holonomic small arcs.First,the least square method is used to quickly calculate the quantization range of the arc parameters,and then the Hough transform method is used to accurately search in this parameter space and convert to accurate arc parameters.Simulation experiment results show that:compared with the traditional least square method,the evaluation algorithm has the characteristics of high calculation accuracy and strong robustness.Compared with the Hough transform method,the calculation rate of the algorithm has been improved.It has advantages when considering both the calculation accuracy and efficiency.
