IMAGE-STITCHING FOR DIMENSIONING

摘要

Dimensioning systems may automate or assist with determining the physical dimensions of an object without the need for a manual measurement. A dimensioning system may project a light pattern onto the object, capture an image of the reflected pattern, and observe changes in the imaged pattern to obtain a range image, which contains 3D information corresponding to the object. Then, using the range image, the dimensioning system may calculate the dimensions of the object. In some cases, a single range image does not contain 3D data sufficient for dimensioning the object. To mitigate or solve this problem, the present invention embraces capturing a plurality of range images from different perspectives, and then combining the range images (e.g., using image-stitching) to form a composite range-image, which can be used to determine the object's dimensions.

主权项

1. A method for dimensioning an object, the method comprising:
positioning a dimensioning system so that at least a portion of an object is contained in the dimensioning system's field-of-view; capturing, using the dimensioning system, a range image of the field-of-view; moving either the dimensioning system or the object so that the dimensioning system's field-of-view contains a different portion of the object; repeating the capturing and the moving until a plurality of range images have been captured; combining the plurality of range images to create a composite range-image; and dimensioning the object using the composite range-image.
