Structured Light and Metrology Technology
We have extensive experience with working with structured lighting techniques. This is the art of using laser lighting, typical in the format of a line, in conjunction with an offset camera to make depth and shape measurement. Typically a laser line is projected onto the shape of interest and a camera views the object at some offset angle to the line generator. This typically shows up a white stripe in the camera image in which the position in image space is proportional to shape. This stripe can used to check shape characteristics or calibrated to get depth information. This technique has be used in conjunction with normal lighting scenarios in order to process both conventional 2-D measurements combined with 3-D measurements.
