地面激光扫描仪的灰度优先距离检校模型

针对加乘常数改正和灰度改正的优先顺序, 提出了灰度优先的距离检校模型。首先分析了脉冲式测距的主要误差源; 然后验证了加乘常数和距离改正表的存在性, 以及灰度对加乘常数的影响, 接着验证了不同距离处距离改正表的一致性; 最后提出了灰度优先的距离检校模型。为了得到不同灰阶的数据, 利用地面激光扫描仪对不同灰阶靶标板进行二维扫描, 并用不同距离的数据, 比较了不同距离检校模型的精度, 实验结果表明, 灰度优先检校模型的精度高于常数优先检校模型的精度, 距离精度提高到5 mm。同时, 灰度优先检校模型的结果不受灰度影响, 具有普适性。

Abstract

For the priority order of the multiplication constant correction and the gray correction, a gray-scale priority calibration model was proposed. Firstly, the main error sources of pulsed ranging were analyzed. Then the existence of the multiplication constant and distance correction table and the influence of gray scale on the multiplication constant were verified. Then the consistency of the distance correction table at different distances was verified. Finally, a gray-scale prionty distance calibration model was provided. In order to obtain different gray-scale data, two-dimensional scanning of different gray-scale target plates was carried out by using ground laser scanner. The accuracy of different distance calibration models was compared by using different distance data. The experimental results show that accuracy of the gray-scale priority calibration model is higher than the precision of the constant priority calibration model, and the distance accuracy is improved to 5 mm. At the same time, the result of the gray-scale priority calibration model is not affected by the gray scale and has universality.
