About Laser Scanning - Triangulation and PointClouds

asked 2014-09-15 10:58:48 -0600

Hello everybody, i working in a project of 360º laser 3d scanning in a turntable (Camera and Laser dont move and the distance to turntable is always the same), but have some questions which i don't find answers for them, then i expect find here.

1º How is the process for detect the position of each point in a captured image ? Like the example below ( vertically contours), but with monochrome, how the process will know which the white stripe/contours is a place who you need place the points ?

image description

2º How is attached each point in a tridimensional space ? Example: p(0,2,7); p(2,6,3);...;.

Thank for Help. Sorry for anything.

Sorry, I don't think OpenCV is what you need. OpenCV mostly does things where a camera is the primary source of input. For a laser scanner, that's not true. Or if it is, what are you even using a laser for instead of just having a white or black background to separate the object from?

If you want to know how to deal with the point cloud data from a laser scanner, you should check out the PCL.
