Patent number: 11017548Abstract: Various embodiments described herein relate to techniques for computing dimensions of an object using multiple range images. In this aspect, the multiple range images are captured from selective locations and satisfy a pre-defined criterion. In accordance with various embodiments, at least a pair of 3D points are identified from the multiple range images, which correspond to at least one geometric feature on a surface of the object. In this regard, a correspondence score is estimated for the identified at least one pair of 3D points. The correspondence score is then utilized for registering the at least one pair of 3D points. Based in part on the registration of the 3D points and 3D point clouds retrieved from the captured images, the dimensions of the object are computed.Type: GrantFiled: June 21, 2018Date of Patent: May 25, 2021Assignee: HAND HELD PRODUCTS, INC.Inventors: Ryan Andrew Lloyd, Scott McCloskey

Patent number: 10859375Abstract: Methods to improve the accuracy of non-contact measurements of an object's dimensions using a dimensioning system are disclosed. The methods include a method for creating a mathematical model (i.e., error model) based on an observed correlation between errors in an estimated dimension and the characteristics of the measurement used to obtain the estimated dimension. These error models may be created for various dimensions and stored for future use. The methods also include a method for using the stored error models to reduce the error associated with a particular dimensioning-system measurement. Here an error model is used to create an estimated error. The estimated error is then removed from the estimate of the dimension to produce a final estimate of the dimension that is more accurate.Type: GrantFiled: December 6, 2019Date of Patent: December 8, 2020Assignee: Hand Held Products, Inc.Inventors: Scott McCloskey, Ryan Andrew Lloyd, Jingquan Li, Brian L.

Patent number: 10679367Abstract: Various embodiments described herein relate to techniques for computing dimensions of a non-cuboid shaped object using angular estimates associated with 3D points captured in an image of a scene including the object. In this regard, a dimensioning system may capture at least one image of the scene including the object and identify one or more planes on the object from the captured at least one image. Further, a surface plane from amongst the one or more identified planes that contains a maximum number of three-dimensional (3D) surface points on the object is determined. Upon determination of the surface plane, angular estimation is determined representing angular values between a normal to the surface plane and a normal to a reference plane. Accordingly, the angular estimation is further used along with an estimated height of the object for computing the dimensions of the object.Type: GrantFiled: August 13, 2018Date of Patent: June 9, 2020Assignee: Hand Held Products, Inc.Inventors: Scott McCloskey, Ryan Andrew Lloyd

Patent number: 10249030Abstract: Obtaining a good image is important for reading indicia. Often, however, objects are not well aligned with an indicia reader's digital imager. This misalignment may lead to images in which an indicium may appear distorted due to perspective. This perspective distortion makes indicia reading difficult. In general, perspective distortion of an imaged object may be corrected using knowledge of the true size, shape, and/or orientation of the physical object. The present invention embraces the use of a dimensioning system to obtain the 3D information necessary to provide this knowledge. Then, using this knowledge, to transform a distorted image of an indicium into a corrected image of the indicium without distortion. This corrected image may then be processed to read the undistorted indicium.Type: GrantFiled: October 30, 2015Date of Patent: April 2, 2019Assignee: HAND HELD PRODUCTS, INC.Inventors: Scott McCloskey, Ryan Andrew Lloyd
