International Classification:

G01C 3/08

US Classification:

356 401, 356 41, 356 501

Abstract:

A method, computer program product, and apparatus for making and displaying measurements based upon multiple 3D range data sets obtained using a 3D rangefinder device. At least a first and a second 3D range data sets are provided. A 3D transformation is computed therebetween. The first 3D range data set is represented as a first displayed image and the second 3D range data set is represented as a second displayed image. At least two features are identified within the first and second displayed images respectively. A measurement is computed based on at least the first feature and the second feature utilizing the 3D transformation between the first and second 3D range data sets. The computed measurement may be displayed within at least one of the first displayed image and the second displayed image.

International Classification:

G01C 3/08

US Classification:

356 401

Abstract:

Method, computer program product, and apparatus for displaying a 2D image data set combined with a 3D range data set. A 3D range data set and at least one 2D image data set which differs from the 3D range data set in resolution, origin, or both, are provided. The 3D range data set is represented as a first displayed image while each 2D image data set is represented as at least a second displayed image. Corresponding features are identified within each displayed image. 3D transformation is computed between the 3D range data set and at least one 2D image data set using the specified corresponding features to establish geometric correspondence. At least one 2D image data set is represented as a third displayed image, wherein a 3D coordinate can be computed for any specified pixel of each 2D image data set using the 3D transformation and 3D range data set.

US Classification:

345619, 382291, 382294

Abstract:

A method, computer program product, and apparatus for specifying, making, and displaying measurements within a 3D range data set obtained using a 3D rangefinder device. A 3D range data set is provided and represented as a first 2D displayed image and a second displayed image. The second displayed image is selected from the group consisting of a second 2D displayed image and a 3D displayed image. At least one feature is identified in the first 2D displayed image and the second displayed image, such that a measurement can be computed based on the identified features. The computed measurement is displayed in at least one of the first 2D displayed image and the second displayed image.

US Classification:

382154, 382190, 715851, 356601

Abstract:

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 selected from the group consisting of a vector, a surface, and a volume, is specified. The calculated geometric entity may be displayed merged within at least one displayed image.

G11C 16/06

US Classification:

365185220

Abstract:

A method, computer program product, and apparatus for obtaining the geometric correspondence between at least two 3D range data sets obtained using a 3D rangefinder device. First and second 3D range data sets are provided. The first 3D range data set is displayed as a 2D displayed image. The second 3D range data set is displayed as one of a second 2D displayed image and a 3D displayed image. Corresponding features within the first 2D displayed image and within the second displayed image are respectively specified. A 3D transformation between the first 3D range data set and the second 3D range data set is computed based on the geometry of the specified corresponding features. As such, that the geometric correspondence between the two 3D range data sets may be determined.

International Classification:

G06K 9/00

US Classification:

382106

Abstract:

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.
