System And Method For Refining Dimensions Of A Generally Cuboidal 3D Object Imaged By 3D Vision System And Controls For The Same

US Patent:
2022035, Nov 10, 2022
Filed:
May 16, 2022
Appl. No.:
17/745087
Inventors:
- Natick MA, US
Hongwei Zhu - Natick MA, US
Daniel Moreno - Northbridge MA, US
Ben R. Carey - Cambridge MA, US
Nickolas J. Mullan - Ambler PA, US
Gilbert Chiang - West Linn OR, US
Yukang Liu - Natick MA, US
David J. Michael - Waban MA, US
International Classification:
G06T 7/62
G06T 7/64
Abstract:
A system and method for estimating dimensions of an approximately cuboidal object from a 3D image of the object acquired by an image sensor of the vision system processor is provided. An identification module, associated with the vision system processor, automatically identifies a 3D region in the 3D image that contains the cuboidal object. A selection module, associated with the vision system processor, automatically selects 3D image data from the 3D image that corresponds to approximate faces or boundaries of the cuboidal object. An analysis module statistically analyzes, and generates statistics for, the selected 3D image data that correspond to approximate cuboidal object faces or boundaries. A refinement module chooses statistics that correspond to improved cuboidal dimensions from among cuboidal object length, width and height. The improved cuboidal dimensions are provided as dimensions for the object. A user interface displays a plurality of interface screens for setup and runtime operation.

System And Method For Calibrating A Plurality Of 3D Sensors With Respect To A Motion Conveyance

US Patent:
2020038, Dec 10, 2020
Filed:
May 18, 2020
Appl. No.:
16/876551
Inventors:
- Natick MA, US
Gang Liu - Natick MA, US
Robert A. Wolff - Sherborn MA, US
David J. Michael - Wayland MA, US
Ruibing Wang - Framingham MA, US
Hongwei Zhu - Natick MA, US
International Classification:
G06T 7/80
H04N 13/246
G06T 7/246
G01B 11/25
Abstract:
This invention provides an easy-to-manufacture, easy-to-analyze calibration object which combines measurable and repeatable, but not necessarily accurate, 3D features—such as a two-sided calibration object/target in (e.g.) the form of a frustum, with a pair of accurate and measurable features, more particularly parallel faces separated by a precise specified thickness, so as to provide for simple field calibration of opposite-facing DS sensors. Illustratively, a composite calibration object can be constructed, which includes the two-sided frustum that has been sandblasted and anodized (to provide measurable, repeatable features), with a flange whose above/below parallel surfaces have been ground to a precise specified thickness. The 3D corner positions of the two-sided frustum are used to calibrate the two sensors in X and Y, but cannot establish absolute Z without accurate information about the thickness of the two-sided frustum; the flange provides the absolute Z information.

US Patent:
2018037, Dec 27, 2018
Filed:
Oct 13, 2017
Appl. No.:
15/784043
Inventors:
- Natick MA, US
Robert A. Wolff - Sherborn MA, US
David J. Michael - Wayland MA, US
Ruibing Wang - Framingham MA, US
Hongwei Zhu - Natick MA, US
International Classification:

Method And System For Metadata Extraction From Master-Slave Cameras Tracking System

US Patent:
2016019, Jun 30, 2016
Filed:
Nov 12, 2015
Appl. No.:
14/939222
Inventors:
- Clovis CA, US
Farzin Aghdasi - Clovis MA, US
Hongwei Zhu - Natick MA, US
Lei Wang - Clovis CA, US
Zhan Jiang Ma - Clovis CA, US
International Classification:
H04N 7/18
G06K 9/62
G06K 9/00
Abstract:
An embodiment of the present invention includes a master camera that may record master metadata regarding an object of interest and communicate the master metadata to a slave camera. The slave camera may zoom, pan, or tilt to isolate and record more detailed image data regarding the object of interest based on the master metadata. In addition, the slave camera may record slave metadata regarding the object of interest. The master and slave metadata may be stored associated with the recorded image data enabling a later search for the object of interest to be expedited. The recorded image data including the object of interest may be identified with greater ease as it may be guided by the master or slave metadata, or a combination thereof. According to embodiments presented herein, processing time for searching and identifying an object of interest may be reduced by enabling a search on the metadata associated with image data, rather than by searching the image data itself
