First Claim
Patent Images
1. A method for generating measurement-conformance feedback using a handheld dimensioning system, the method comprising:
- capturing by a dimensioning-system image-sensor at least one image of at least one object in a handheld dimensioning-system field-of-view;
computing by a dimensioning-system processor using the at least one image a measurement geometry, the measurement geometry being an orientation and spatial relationship between the handheld dimensioning-system and the imaged object;
deriving by a dimensioning-system processor a measurement accuracy corresponding to the measurement geometry;
identifying by a dimensioning-system processor at least one conformance criteria based on the measurement accuracy, the conformance criteria being a predetermined measurement accuracy standard or reference;
obtaining by a dimensioning-system processor using the at least one image a dimension measurement;
comparing by a dimensioning-system processor the dimension measurement to the conformance criteria; and
generating by a dimensioning-system processor measurement-conformance feedback corresponding to the results of comparing the dimension measurement to the conformance criteria.

Abstract
A system and method for obtaining a dimension measurement that conforms to a conformance criteria is disclosed. The dimensioning system provides either (i) feedback to confirm that the measurement complies with the criteria or (ii) information on how the measurement geometry could be adjusted in order to provide a compliant measurement in a subsequent dimension measurement.

17. A handheld dimensioning system providing measurement-conformance feedback, the dimensioning system comprising:
-
an imaging subsystem comprising at least one image sensor for capturing an image of at least one object within a field-of-view; and a control subsystem communicatively coupled to the at least one image sensor, the control subsystem comprising at least one processor and at least one non-transitory storage medium for storing information and processor-executable instructions, wherein the processor-executable instructions configure the processor to; (i) receive images from the at least one image sensor, (ii) compute using the received images a measurement geometry, the measurement geometry being an orientation and spatial relationship between the handheld dimensioning-system and the imaged object, (iii) derive a measurement accuracy corresponding to the measurement geometry, (iv) identify a conformance criteria based on the measurement accuracy, the conformance criteria being a predetermined measurement accuracy standard or reference, (v) obtain using the received images a dimension measurement, and (vi) compare the dimension measurement to the conformance criteria in order to generate measurement-conformance feedback. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
