Mapping Techniques Using Probe Vehicles
First Claim
1. A method for mapping terrain including one or more roads, comprising:
- equipping a probe vehicle with cameras, DGPS and appropriate illumination including at least one laser pointer;
obtaining images using the cameras when illuminating an area being imaged using the at least one laser pointer;
obtaining position information using the DGPS while the camera is obtaining images; and
converting the images to a map at a remote location apart from the vehicle using the position information.

Abstract
Method for mapping terrain including one or more roads includes equipping a probe vehicle with cameras, accurate RTK DGPS and appropriate illumination including at least one laser pointer, obtaining images using the cameras when illuminating an area being imaged using the laser pointer(s), obtaining position information using the DGPS while the camera is obtaining images, and converting the images to a map at a remote location apart from the vehicle using the position information. Infrared illumination in the eye-safe portion of the spectrum is directed into the area being imaged in conjunction with the cameras such that the cameras obtained images of illuminated areas.

17. A computer-based system for mapping a road, comprising:
-
a plurality of vehicles, each vehicle comprising at least one camera that obtains images of the road and its vicinity during travel of the vehicle and a positioning system that enables the vehicle to determine its position while travelling using GPS; and a processor situated apart from the vehicle that receives from each vehicle, the images obtained by said at least one camera along with position information about the vehicle when each image was obtained and converts the images into a map of the road. - View Dependent Claims (18, 19, 20, 21, 22)
