Automated landmark extraction from three-dimensional whole body scanned data
InactiveUS20060171590A1Simple processExpand marketing channelSpecial data processing applicationsClothes making applicancesHuman bodyPoint cloud
A method for automated landmark extraction from three-dimensional whole body scanned data extracts feature points as landmarks from a plurality of point clouds obtained from a three-dimensional whole body scanner, without pre-making the landmarks on a human body before scanning. The system includes: (1) Silhouette analysis, which projects three-dimensional body scanned data onto a two-dimensional surface and observes the variations in curvature and depth; (2) Minimum circumference, which uses the variations of the circumference of body parts to define the locations of the landmarks and feature lines; (3) Gray-scale detection, which converts the color information of human body from RGB values into gray-scale values to locate the landmarks with greater variations in brightness; and (4) Human-body contour plot, which simulates the sense of touch to locate landmarks by finding the prominent and concave parts on the human body.

Digital Rendering Method for Environmental Simulation
InactiveUS20130016099A1Less processing powerVideo games3D-image renderingDisplay deviceEnvironmental simulation
A method for producing video simulations uses two-dimensional HDR images and LIDAR optical sensor data to deliver a photo-realistic simulated sporting event experience to a display. The playing environment is mapped using a data collection process that includes contour mapping the environment, photographing the environment, and associating the images with the contour mapping data. Preferably, the HDR camera is used in conjunction with a differential global positioning system that records the position and heading of the camera when the photo is taken. A polygon mesh is obtained from the contour data, and each image is projected onto a backdrop from the perspective of a simulated camera to create a set, which is then stored in a set database. The simulated environment is created by selecting the set needed for the simulation and incorporating simulation elements into the set before rendering the simulated camera's view to the display.

Method for automated text placement for contour maps and chart
InactiveUS20050288853A1Instruments for road network navigationRoad vehicles traffic controlTerrainContour tree
A method for automatically placing textual information (labels) on contour maps according to modern cartographic conventions is described. A three-step process is used: in the first step contours are organized into a contour tree (a special data structure) comprised of contour groups. Each group serves as a node in the tree and corresponds to a terrain structure. The second step devises profiles emitted from the peak of a group in a discrete number of directions. Only contours intersected by a profile, and the intersections presenting a monotone curve on the surface of a single terrain structure, are associated with the profile. A processed profile serves as the basis for an array of contour labels which are aligned along the profile. The cartographic merit of every profile is evaluated during this step. The final step renders the positions of contour labels along a profile which is taken by its merit value. Constraints such as the distance between multiple labels of a contour, the reversing of reading directions of a label allowed on a non-standard profile, and the criterion for conflict-free placement play critical roles in the selection of a label.
