摘要：

For the automatic measurement of light angle instrument, all of the experimental light sources have nonlinear attenuation characteristics. A nonlinear compensation method based on polynomial fitting is proposed and a specific experiment is given. The computer controlled equipment is designed as a sensor with an unknown tilt angle to automatically capture the incident light illumination angle. The compensation method model is a polynomial curve fitted through the least square method. It is shown that the compensation result makes the calibrated angle sensor more accurate in outdoor experiments than the uncompensated angle sensor
