Dimensioning system calibration systems and methods

A method of operation of a dimensioning system device, the method comprising:

• detecting via a dimensioning system sensor communicably coupled to a dimensioning system processor, a selective coupling of an imaging system device to the dimensioning system device, the imaging system including at least one imaging system image sensor and at least one imaging system display;
• capturing by the dimensioning system device a depth map via the dimensioning system sensor;
• capturing by the dimensioning system device an intensity image via the dimensioning system sensor;
• receiving by the dimensioning system device imaging system image data, the imaging system image data representing an image captured by the at least one imaging system image sensor;
• and
• determining by the dimensioning system device a number of extrinsic parameters that provide a correspondence between a point in the depth map and intensity image as viewed by the dimensioning system sensor with a same point as viewed by the at least one imaging system image sensor of the imaging system device including:
• determining by the dimensioning system device a number of points positioned on at least one feature in the depth map and the intensity image including:
• determining by the dimensioning system device a minimum of at least eight points positioned on at least one feature in the depth map and the intensity image, the at least one feature including an item other than a calibration target;
• and
• determining by the dimensioning system device an equal number of respective points similarly positioned on the at least one feature in the imaging system image data.

A method of calibrating a dimensioning system device upon communicably coupling the dimensioning system device to an imaging system including an imaging system display and an imaging system image sensor, the method comprising:

• receiving by the dimensioning system device a depth map and an intensity image of a scene provided by a dimensioning system sensor in the dimensioning system device, the depth map and the intensity image including a common plurality of three-dimensional points;
• receiving by the dimensioning system device an imaging system image data from the imaging system image sensor, the imaging system image data comprising a plurality of visible points, at least a portion of the plurality of visible points corresponding to at least a portion of the plurality of three-dimensional points;
• determining via the dimensioning system device a number of points positioned on at least one feature appearing in the depth map and intensity image with a same number of points similarly positioned on the at least one feature appearing in the imaging system image data, the at least one feature not including a calibration target;
• determining by the dimensioning system device a number of extrinsic parameters spatially relating each of the number of points in the depth map and the intensity image with each of the respective, same number of points in the imaging system image data.
