SYSTEMS AND METHODS FOR ENHANCING DIMENSIONING

摘要

A dimensioning system can include stored data indicative of coordinate locations of each reference element in a reference image containing a pseudorandom pattern of elements. Data indicative of the coordinates of elements appearing in an acquired image of a three-dimensional space including an object can be compared to the stored data indicative of coordinate locations of each reference element. After the elements in the acquired image corresponding to the reference elements in the reference image are identified, a spatial correlation between the acquired image and the reference image can be determined. Such a numerical comparison of coordinate data reduces the computing resource requirements of graphical comparison technologies.

1. A portable structured light dimensioning system to determine a volume dimension of an object, comprising:
an image acquisition device to acquire image data representative of an element pattern projected into a three-dimensional space that includes an object; a processor communicably coupled to the image acquisition device; and a non-transitory storage medium communicably coupled to the processor and having stored therein machine executable instructions that when executed by the processor cause the processor to:
determine coordinate data associated with element locations in a portion of the element pattern present in the acquired image data;generate a number of coordinate data lists, each including coordinate data associated with at least three element locations in the acquired image data;for each coordinate data list:
compare the coordinate data associated with each of the at least three element locations in the acquired image data with a reference data list including reference coordinate data associated with reference element locations in a reference element pattern; andselect for each of the at least three element locations, a corresponding reference element location in the reference element pattern;determine a spatial shift between the coordinate data associated with each of the at least three element locations in the acquired image data and the coordinate data associated with the respective corresponding reference element location in the reference element pattern; andsort the coordinate data using a defined sort pattern to provide a respective ordered coordinate data list;generate an ordered coordinate data list about each of a number of points of interest in the acquired image data to provide the number of ordered coordinate data lists, each ordered coordinate data list including coordinate data associated with each of at least three element locations about each respective point of interest; andaccept a number of user inputs, each of the user inputs corresponding to one of the number of points of interest in the acquired image data.
