| Abstract: | The BRDF definition and its measure principals were developed. The forming reasons of error was analyzed theoretically; the error factors which influence the system measure accuracy were analyzed quantitatively. A BRDF error analysis method was introduced by using the RMS error calculation method. Finally, the analyzed theory result was verified by the experimental calibration method. The analyzed theory result matches well with the experimental calibration result, which provides the new method and thinking ways for the effective BRDF system evaluations. |
