Reaserch on precision measurment for large scale 3D surface based on superior integration

We developed a new type of 3D measurement system for large scale object or outdoor measurement which enabled us to obtain successive 3D range data applied superior integration technology. An object for computer 3D point clouds requires two following information: range information and 3 dimensions coordinate of each point about this object. We proposed superior integration technology using two mainly sensors: laser rangefinder and 2 axis compass. In this paper, we use a living example that measured a wind power tower outside to show how to get morphology of large scale object. In addition, large scale object have to be measured stay outside which may be very large extent. So we use the wireless transmission of multi-serial port technology to solve the problems that the venues are too large and the wires are too much.
