CloudCompare forum

Got another question for you, Daniel. Does this math account for the rotation based on the origin point, as you told me in my previous question you answered (linked below)? I ask this because the shift I am seeing in the coordinates (due to the translation vector) is larger than I expected. If my ma...

Thanks for all the help recently, Daniel! Much appreciated.

Disregard that last sentence about the assumption of x y and z. That is wrong.

Not sure if this is the right place to ask this question. I am trying to apply a rigid transformation matrix generated from CloudCompare to a pair of coordinates, but my linear algebra skills are not the greatest. I attached a screenshot of the math I was doing. The 4x4 matrix you see is the transfo...

Another question. My rotation is pretty small in my example, no? Assuming it is small, it would still make that big of a difference to the translation vector? Thanks in advance.

Thanks for the reply! So the rotation vector rotates the point cloud based the origin point (0, 0, 0), which would in turn make the translation vector larger? Is this correct? I was trying to determine if it would be possible to take the transformation matrix generated and apply it to a shapefile, t...

I have a rigid transformation matrix generated after using the ICP registration between two different point clouds. When visualizing the shift between the non-registered and registered point clouds, it is obvious that there wasn't much of a shift (at least in the x and y coordinates). However, when ...

I want to find the time stamp of a single point in a point cloud. Essentially, I am trying to clip and remove self-overlap generated from an aircraft and my workflow was to get the starting time stamp of where the self-overlap starts and where it ends. Is it possible to get the time stamp of a point...

Thanks!

Need to export a point cloud as a .jpeg, but there is no option to change the DPI. Is this possible?
