有没有办法使用 lidR 包在 x 和 y 轴上绘制“'true'”坐标
Is there a way to plot the ''true'' coordinates on the x and y axis using lidR package
我想使用 lidR 包在 R 中绘制点云。当我绘制点云时，它会自动使用坐标从 0 开始归一化的 x 和 y 轴值，我想从 las 数据集的属性中查看实际坐标。
LASfile <- system.file("extdata", "MixedConifer.laz", package="lidR")
las <- readLAS(LASfile)
plot(las, axis = TRUE)
这在 plot
中有记录
clear_artifacts logical. It is a known and documented issue that the 3D visualisation with rgl displays artifacts. The points look aligned and/or regularly spaced in some view angles. This is because rgl computes with single precision float. To fix that the point cloud is shifted to (0,0) to reduce the number of digits needed to represent its coordinates. The drawback is that the point cloud is not plotted at its actual coordinates.
plot(las, axis = TRUE, clear_artifacts = FALSE)
这也以某种方式记录在 chapter 2.3 of the book 中。
