Provided your LIDAR sensor does the distance calculation, an Arduino might serve to control the LIDAR sensor's orientation/direction. Or - with a fixed LIDAR sensor - control the objects's orientation. Beyond that, IMHO an arduino is of little avail.

One software (PC-based) to consider might be Faro's SCENE LT ( https://knowledge.faro.com/Software/FARO_SCENE/SCENE ).

i am having a lidar sensor TFMINI having range 12 meter and i am getting 2 things in output distance and strength . can i create 3D image from this data?

U. Dreher Ufuk Fatih Küçükali

Consider the TFmini a point probe: at a given time, you get the distance to a single point in space.

To get a 3D image, you'll need a lot of points.

The simplest way is to put an object to be scanned on a rotating base, moving the sensor vertically (scanning a vertical line), hen rotating the object a bit, hen repeating the vertical sensor movement. This way you could gather the multitude of points to create a 3D image of the object.

Got that?

U. Dreher thank you sir !! yes i got that .. but what to do with the strength?

I don't think the strength is of much use in this application. Eventually you could use it to exclude points below a certain strength threshold to eliminate somewhat "dubious" points.
