Measurement of a Single Standing Tree Volume Based on Three-Dimensional Laser Scanner System

With the application of the three-dimensional laser scanner, it makes possible that measure the shape and size of the sanding tree accurately. In this paper we put forward a new approach to reckon the volume of a single standing tree with three-dimensional laser scanner, explain the principle of the three-dimensional laser scanning system and how to establish the model of a single standing tree based on three-dimensional laser scanner and computer program. We have a test for a single standing tree volume with three-dimensional laser scanner, and also expatiate the specific process of reckoning the volume of a single standing tree with the model. As shown by the test, we can work out fast and exactly the single standing tree volume. If the approach can be apply on the measurement of stand volume, there has a great improvement in the precision and efficiency of measurement.
