Abstract
A handheld dimensioning system that analyzes a depth map for null-data pixels to provide feedback is disclosed. Null-data pixels correspond to missing range data and having too many in a depth 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.
Claims20
A method for obtaining a dimension measurement using a handheld dimensioner, the method comprising:
- receiving, using a processor, range data from a dimensioning subsystem;
- creating, using the processor, a depth map from the range data;
- determining, using the processor, a null-data pixel-count from the depth map, the null-data pixel-count comprising a sum total of null-data pixels;
- and
- computing, using the processor, a dimension measurement if the null-data pixel-count is at or below a threshold count, or
- generating, using the processor, an error feedback if the null-data pixel-count is above the threshold count.
A handheld dimensioning system configured to provide error feedback, the dimensioning 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 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 range data from the dimensioning subsystem, (ii) create a depth map from the range data, (iii) process the depth map to obtain a depth-map quality, and (iv) generate an error feedback if the depth-map quality is below a minimum-quality threshold.
