Abstract: System and methods for obtaining sizing of an irregularly shaped object. The methods comprise: displaying, by a display of a handheld scanner system, a 3D optical figure of a subject; displaying a grid superimposed over the 3D optical figure of the subject, the grid comprising a plurality of marks arranged in rows and columns; generating, by a radar module of the handheld scanner system, range data specifying a sensed spacing between the radar module and at least a surface of a first portion of the irregularly shaped object which is covered by at least one item; receiving, by a processor of the handheld scanner system, the range data from the radar module as the subject is being scanned; and causing at least one first visual characteristic of a first mark of said plurality of marks to change when corresponding range data is successfully received by the processor.

Abstract: A handheld scanner system for obtaining sizing of an irregularly shaped object. The system includes a housing and an inertial measurement unit configured to record orientation and displacement history of the housing. An optical module includes at least one 3D optical sensor configured to generate a 3D point cloud of information about the object. A radar module includes at least one radar sensor configured to sense spacing between the housing and the object. A processor receives data from the inertial measurement unit, the optical module and the radar module and creates a map representing the object based on the received data.
