Abstract

A method and a system for determining horizontal velocity of a construction vehicle and a distance from a range sensing apparatus to a surface is provided. In an embodiment, a plurality of video images of the surface generated by a video camera is received, an angular velocity is calculated by video processing, a distance from each of a plurality of laser rangefinders to the surface is measured, and linear horizontal velocity is calculated from angular velocity and distances.
