摘要
激光扫描测量技术已广泛应用于小尺度船模通航试验中,由于在测量过程中,不可避免会产生随机误差,从而影响到测量结果的准确性。通过分析误差产生的原因,采用平滑与滤波的技术有效地减少了随机误差对结果的影响。经平滑处理后,其相对误差约7‰。
The technology of laser scanning measurement has been widely applied in small size ship model's navigation test. During the measurement, random errors will be generated unavoidably, and the accuracy of measured result affected. The reason of error generated is analyzed. And the technology of smoothing and filtration would reduce the influence of random error effectively. Through an illustration, the relative error of the measured data is about 7‰.
