摘要：It is thought that the use of bidirectional reflectances measured by satellites enables the estimation of vegetation biomass. We have developed a simulator to estimate the bidirectional reflectance, in order to develop and validate algorithms using bidirectional reflectance. This simulator is used to calculate three-dimensional model, and the result greatly depends on the accuracy of 3D model to use. Therefore, I propose a method to correct the angular data of the helicopter. If the measurement is along with a helicopter equipped with laser scanner and digital camera, relative position of the image data taken by digital camera and laser range data can be easily noticed. In this fact, angle can be calculated with simple math
