POINT CLOUD DATA PROCESSING DEVICE, POINT CLOUD DATA PROCESSING SYSTEM, POINT CLOUD DATA PROCESSING METHOD, AND POINT CLOUD DATA PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2012/005140
Kind Code:
A1
Abstract:
A point cloud data processing device comprises: a non-plane region removing unit (101) for removing point cloud data involved in a non-plane region, which cause a large computational load, from point cloud data associating a two-dimensional image of an object to be measured with three-dimensional coordinate data of a plurality of points constituting this two-dimensional image; a plane labeling unit (102) for assigning a label for specifying a plane to the point cloud data obtained after removing the data of the non-plane regions; a contour calculation unit (103) for calculating the contour of the object by using a local plane based on a local region continuing from the plane to which the label is assigned; and a point cloud data reacquisition request processing unit (106) for requesting for the reacquisition of point cloud data in order to enhance accuracy.
