Abstract
A data capture system for object dimensioning includes: a projector to project a structured light pattern onto a capture volume to illuminate an object in the capture volume; a depth sensor; a set of image sensors; and a processor configured to: responsive to detection of the object, control the depth sensor to obtain a depth scan of the object; based on the depth scan, determine an attribute of the object; select projection parameters based on the attribute; control the projector to illuminate the object according to the projection parameters; and control the set of image sensors to capture respective images of the object.

A data capture system for object dimensioning, comprising:
- a projector to project a structured light pattern onto a capture volume to illuminate an object in the capture volume;
- a depth sensor;
- a set of image sensors;
- and
- a computing device configured to:
- responsive to detection of the object, control the depth sensor to obtain a depth scan of the object;
- based on the depth scan, determine an attribute of the object;
- select projection parameters based on the attribute by selecting one of a predefined set of classes according to the attribute, and selecting the projection parameters corresponding to the selected class;
- control the projector to illuminate the object according to the projection parameters;
- and
- control the set of image sensors to capture respective images of the object.
