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: 10402956Abstract: 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.Type: GrantFiled: September 25, 2018Date of Patent: September 3, 2019Assignee: Hand Held Products, Inc.Inventors: Brian L.

Patent number: 10228452Abstract: A method is presented for correcting errors in a 3D scanner. Measurement errors in the 3D scanner are determined by scanning each of a plurality of calibration objects in each of a plurality of sectors in the 3D scanner's field of view. The calibration objects have a known height, a known width, and a known length. The measurements taken by the 3D scanner are compared to the known dimensions to derive a measurement error for each dimension in each sector. An estimated measurement error is calculated based on scans of each of the plurality of calibration objects. When scanning target objects in a given sector, the estimated measurement error for that sector is used to correct measurements obtained by the 3D scanner.Type: GrantFiled: June 7, 2013Date of Patent: March 12, 2019Assignee: HAND HELD PRODUCTS, INC.Inventors: Brian L.

Patent number: 9857167Abstract: A current problem with 3D scanners using structured light patterns is choosing a single light pattern to accommodate all possible object/range conditions. Objects far from the 3D scanner often require different patterns than objects that located close to the 3D scanner. In addition, large objects often require different patterns than small objects. To automatically sense and adapt to a wide variety of size/range conditions, the present invention embraces a 3D scanner for dimensioning that has two projectors for projecting two different light patterns. Based on the scanning requirements for a particular object, one of the two projected patterns may be used to obtain information regarding the shape of an object. In one possible embodiment, this shape information is used to obtain the object's dimensions.Type: GrantFiled: June 23, 2015Date of Patent: January 2, 2018Assignee: Hand Held Products, Inc.Inventors: Brian L.
