图像匹配点云与激光扫描点云的模型重建对比

Comparison of model reconstruction between image matched point clouds and laser scanned point clouds

为分析图像匹配点云与激光扫描点云的模型重建效果与精度,文中使用同时获取的孔子图像数据与激光扫描点云数据,进行加工与建模处理,并定性定量的评估了两种模型重建方式的可视化效果与模型精度。结果表明:激光扫描点云数据是高精度模型重建的最佳数据,在精度要求不高的前提下,图像匹配点云可作为真实场景仿真的有效数据。

To analyze the model reconstruction result and accuracy of image matched point clouds and laser scanned point clouds,in this paper,laser point clouds and images data of Kongzi were acquired simultaneously to carry out the processing and the modeling,the visualization effect and the model accuracy of the two model reconstruction methods were evaluated qualitatively and quantitatively. The results indicated that laser scanned point clouds were the best data source for high-accuracy model reconstruction,image matched point clouds could be used as valid data for real scene simulation under the premise that accuracy was not high.
