Laser rangefinder: distance to the first object on its path is measured.
Laser: emits a pulse of light. Detector: reflected light is seen.
Timing the round-trip time of a pulse of light.
Human stereoscopic vision based.
Two video cameras are arranged.
Differences between the images seen by each camera.
Determine the distance at each point in the images.
Laser on the object
A camera looks for the location of the laser dot. Laser dot, camera and laser emitter form a triangle.
Multiple images under varying lighting conditions.
Surface orientation at each pixel.
Photos are taken around an object against a background.
Outlines created from a sequence of photos.
Silhouettes are extruded and intersected.
Visual hull approximation of the object.
Some concavities are not detected.
A laser dot or line is projected onto an object.
Handheld laser device and a sensor is applied.
Position of the scanner is recorded (laser tracker).
