Automatic mode switching in a volume dimensioner
First Claim
1. A dimensioning system, comprising:
- a range camera configured to capture a first light pattern image projected onto an object from a first view, in response to a determination that the object has a flat side and an obtuse angle not facing a point of view of the dimensioning system and generate a first range image based on the first light pattern image; and
a processor communicatively coupled to the pattern projector and the range camera, wherein the processor is configured by software to;
calculate a first set of dimensions of the object based on the first range image;
cause the range camera to capture a second light pattern image of the object from a second view, in response to a determination that the object has a non-flat side and an obtuse angle facing the point of view of the dimensioning system based on the first set of dimensions and generate a second range image based on the second light pattern image, wherein the second view is different from the first view;
calculate a second set of dimensions of the object based on the second range image; and
determine a minimum bounding box for the object, defined by the projected light pattern onto the object, based at least on the first set of dimensions and the second set of dimensions.

Abstract
Dimensioners and methods for dimensioning an object includes capturing, using a dimensioning system with a single sensor, at least one range image of at least one field-of-view, and calculating dimensional data of the range images and storing the results. Wherein, the number of views captured of the object is automatically determined based on one of three modes. The first mode is used if the object is a cuboid, or has no protrusions and only one obtuse angle that does not face the point of view, where it captures a single view of the object. The second mode is used if the object includes a single obtuse angle, and no protrusions, where it captures two views of the object. The third mode is used if the object includes a protrusion and/or more than one obtuse angle, overhang, protrusion, or combinations thereof, where it captures more than two views of the object.

11. A method for dimensioning an object using a dimensioning system, comprising:
-
generating a first range image of the object from a first view, in response to determining that the object has a flat side and an obtuse angle not facing a point of view of the dimensioning system; calculating a first set of dimensions of the object based on the first range image; generating a second range image of the object from a second view, in response to determining that the object has a non-flat side and an obtuse angle facing the point of view of the dimensioning system based on the first set of dimensions, wherein the second view is different from the first view; calculating a second set of dimensions of the object based on the second range image; and determine a minimum bounding box for the object, defined by a projected light pattern onto the object, based at least on the first set of dimensions and the second set of dimensions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
