Abstract
A system and method for structured-light dimensioning is disclosed. The method includes combining multiple images using different camera settings to provide all of the information necessary dimensioning. What results is an improved ability to sense a light pattern reflected from an object's surfaces, especially when the lighting and/or object color make imaging all surfaces simultaneously difficult.
Claims20
A structured-light dimensioning system, comprising:
- a projector subsystem for projecting a light pattern onto an object, said object having dimensioning surfaces;
- a camera subsystem for capturing pattern images, the pattern images comprising the light pattern on the dimensioning surfaces;
- a control subsystem communicatively coupled to the projector subsystem and the camera subsystem, the control subsystem comprising (i) a processor for analyzing and processing the pattern images and (ii) a memory for storing the pattern images and a software program, wherein
- the software program when executed by the processor configures the control subsystem to (i) enable the camera subsystem to capture multiple pattern images, each pattern image captured using different camera-subsystem settings and (ii) incorporate the multiple pattern images into an image composite with a resolvable light pattern on the dimensioning surfaces.

A method to compute an object's dimensions using a structured-light dimensioning system, the method comprising:
- capturing a pattern image of a light pattern projected onto the object;
- selecting dimensioning surfaces on the object in the pattern image;
- identifying dimensioning surfaces that have a requisite pattern for dimensioning;
- incorporating the pattern image into an image composite;
- adjusting a camera subsystem's settings and repeating the capturing, selecting, identifying, and incorporating until the image composite has the requisite pattern for dimensioning on all dimensioning surfaces;
- and
- processing the image composite to compute the object's dimensions.
