Abstract
This invention relates to a three-dimensional image of ground surface and the method and system that generates the three-dimensional image. Here, a three-dimensional image is an image that has three-dimensional XYZ coordinates in a ground coordinate system for every pixel of the image and the ground surface means the bare-earth surface plus all the objects on the bare-earth surface. The scene covered and represented by such a three-dimensional image is a three-dimensional real world scene where everything visible in the three-dimensional image has three-dimensional coordinates. The three-dimensional XYZ coordinates of all the pixels of a three-dimensional image are attributed by the method and system of this invention for generating three-dimensional images with airborne oblique/vertical imagery, GPS/IMU, and LIDAR ground surface elevation or range data. On such a three-dimensional image, one can make direct measurements of location, length, distance, height, area, and volume and indirect measurements including but not limited to profile and sight of view all in the real world three-dimensional coordinate system. Additionally, application systems that utilize three-dimensional imag…
