Method and apparatus for displaying a calculated geometric entity within one or more 3D rangefinder data sets

摘要

A method, computer program product, and apparatus for displaying a calculated geometric entity within at least one 3D range data set obtained using a 3D rangefinder device. At least a first 3D range data set is provided. Each 3D range data set is displayed as at least one displayed image. A calculated geometric entity that represents a non-physical entity is specified. The calculated geometric entity is displayed merged within at least one displayed image, where the calculated geometric entity represents something other than the physical objects represented by the first 3D range data set.

1. A method for displaying a calculated geometric entity within at least one 3D range data set, comprising:
at a computer processor for rendering 3D range data as a 2D displayed image:
representing a provided first 3D range data set as at least one 2D displayed image, wherein the first 3D range data set represents physical objects of a scene;specifying a calculated geometric entity for representing a non-physical entity, wherein the calculated geometric entity represents something other than the physical objects represented by the first 3D range data set, wherein the calculated geometric entity is not represented by the first 3D range data set, and wherein specifying at least some part of the calculated geometric entity is provided from the group consisting of: manually entering the calculated geometric entity, entering the calculated geometric entity from a computer file, automatically entering the calculated geometric entity, and combinations thereof; anddisplaying the calculated geometric entity merged within the at least one 2D displayed image, wherein displaying the calculated geometric entity comprises displaying the calculated geometric entity as at least one of a calculated 2D or 3D vector, a calculated surface, a calculated volume, a trajectory, a sight line, and combinations thereof.
