Description
Creates a Terrestrial Laser Scanner (TLS - also called a Ground Based Lidar = GBL) sensor entity attached to the selected cloud.
The user must specify the main intrinsic and extrinsic parameters of the sensor (absolute position and orientation, angular steps, etc.).
Notes: - since version 2.5.6, angles are now expressed in degrees and aircraft denominations (yaw/pitch) are used so as to make things clearer. - since version 2.14, it is possible to manually set the scanner angular ranges
Clicking on the 'OK' button will create a new sensor object. A depth buffer is automatically generated and displayed by CloudCompare so as to let the user visually check the parameters. Note that the parent cloud of the sensor is used to create this depth buffer, considering the farthest point 'seen' by the scanner in any direction.
By default the sensor object is added as a child of the selected cloud in the DB tree. It is also visible in the 3D view (warning: you may have to change its 'drawing scale' - see the sensor object properties - to view it correctly).
