Dimensioning system with feedback
First Claim
Patent Images
1. A method, comprising:
- receiving, with a processor, range data from a dimensioning subsystem;
creating, with the processor, a distance map from the received range data;
determining, with the processor, a null-data pixel-count from the distance map, the null-data pixel-count comprising a sum total of null-data pixels; and
computing, with the processor, a dimension measurement if the null-data pixel-count is at or below a threshold count, orgenerating, with the processor, an error feedback if the null-data pixel-count is above the threshold count.

Abstract
A dimensioning system that analyzes a distance map for null-data pixels to provide feedback is disclosed. Null-data pixels correspond to missing range data and having too many in a distance map may lead to dimensioning errors. Providing feedback based on the number of null-data pixels helps a user understand and adapt to different dimensioning conditions, promotes accuracy, and facilitates handheld applications.

15. A system, comprising:
-
a dimensioning subsystem comprising at least one image sensor for capturing range data of an object or objects within a field-of-view; and a processor communicatively coupled to the at least one image sensor, wherein the processor is configured to; receive range data from the dimensioning subsystem; create a distance map from the range data; process the distance map to obtain a distance-map quality comprising a sum of the number of pixels in the distance map having insufficient information to determine distance; and generate an error feedback if the distance-map quality is below a minimum-quality threshold. - View Dependent Claims (16, 17, 18, 19, 20)
