Structured Light

- Project light patterns and detect correspondence

- Perform a triangulation between matching points

Pros: Low price high accuracy, High resolution

Cons: Limitation in sensing range (50cm~2m) and dynamic imaging, Occlusion

Time-of-Flight Principle

Reflected IR shows phase delay proportional to

the distance from the camera.

Time-of-flight of Light Distance

: It is not simple to measure the flight time

directly at each pixel of any existing image

sensor

Laser Scanning

- Structured Light, Time-of-Flight principles are applied

with Laser Light
