The present application claims the benefit of U.S. Patent Application No. 61/872,299 for a System and Method for Package Dimensioning filed August 30, 2013. The foregoing patent application is hereby incorporated by reference in its entirety.
Figure 1 is a block diagram illustrating an exemplary package-dimensioning system according to the present invention.
Figure 2 is a block diagram illustrating an exemplary alternative embodiment of an exemplary package-dimensioning system according to the present invention.
Figure 3 is a block diagram illustrating an exemplary package-dimensioning system according to the present invention.
Referring now to Figures 1 and 2, the package-dimensioning system 100 according to the present invention includes an image-capturing subsystem 110. The image-capturing subsystem 110 acquires information about an object within the image-capturing subsystem's 110 field of view. Typically, the image-capturing subsystem includes an imaging device (e.g., camera, stereo camera, range camera 110A, lidar). The imaging device may be any sensor that provides information from which a computer can build an organized 3D point cloud. An organized point cloud has 3D points arranged in a 2D matrix, which corresponds to the rasterization of the range image. Typically, the image-capturing system is configured to generate a point cloud with respect to the object within its field of view. The point cloud usually contains information regarding the positioning of points in a three-dimensional space (e.g., X, Y, Z coordinates) within the field of view of the image-capturing subsystem 110 when the range image is acquired, including points on the surface of the object 112. The information regarding the positioning of points on the surface of the object is referred to as object information.
Object information relating to an image of a regular box, for instance, will be dominated by points with zero curvature (c = 0) and with orientations parallel or orthogonal to the ground (θ = π/2 radians or θ = 0 radians). By way of further example, object information relating to an image of a cylinder lying flat will have non-zero curvature (c > 0) and a continuous range of orientation with respect to the ground (e.g., θ = [0 radians, n radians]). The feature set as a whole, therefore, describes an object's surface features (e.g., planar surfaces, curved surfaces). Typically, the feature set takes the form of a relative histogram (e.g., 2D relative histogram). By way of example, a typical histogram might use (i) ten uniform bins for curvature c, ranging from 0 to 0.08 and (ii) 20 uniform bins for orientation θ, varying from 0 to π radians.
Referring now to Figure 3, the package-dimensioning system 100 embraced by the present invention may be adapted to estimate the dimensions of a plurality of objects 112 within the field of view of the image-capturing subsystem 110. To accomplish this, the system 100 typically must segment the objects 112 that are above the ground plane (e.g., supporting surface) within the field of view of the image-capturing subsystem 110. Typically, Euclidian clustering is employed to segment the objects 112 in an organized point cloud, whereupon the system 100 processes each segmented portion of the point cloud associated with a distinct object in the manner described above.
