提高三维激光扫描系统图像质量技术的研究

Research on technique of improving quality of 3D laser scan system

对其中三维激光扫描图像处理的关键技术———二值化、细化以及离散数据点云的滤波进行了研究,提出了一种先加权中值滤波,然后再小波分析滤波的新的降噪方法,并通过遗传算法对权重值进行了优化。在通常情况下,由于小波分析计算工作量大,所以提出了一种相对简单的算法,实现了在单台PC机上的运算。

Several key techniques on image processing are studied,including binarization,thinning and filtering. A new denoising method is proposed. This method uses weighting median filtering first,then uses wavelet analysis. At the same time, the weight is improved through using genetic algorithm. The calculative work of wavelet analysis is always very large, a relative simple method is provided, so that calculation can be done on PC computer.
