Hello, how are you? I have a 3D coordinate system. My system was obtained from a LIDAR sensor. Do I need to project the 3D point clouds on the 2D flat image? I have to project my points considering the LIDAR coordinates as x: forward, y: left and z: up. However, my points were obtained by considering the following coordinates as x: right, y: down and z: forward. So how do I convert / rotate from the second convention (x: right, y: down, and z: forward) to the first convention (x: forward, y: left, and z: up)?
I thank you for your attention,
Gledson

Point cloud data can be displayed using pcshow.The syntax of pcshow is
pchow(ptCloud)
where ptCloud is a Point cloud object.Once the point cloud data was displayed, you may use your mouse to rotate the points.Please refer https://in.mathworks.com/help/vision/ref/pcshow.html for more information regarding pcshow.
Hope this helps!
