title = "Calibration of the reflectivity-related error of the indirect time-of-flight imaging systems",
abstract = "The indirect time-of-flight imaging system possesses the characteristics of high real-time, high integration, and low cost, so it has a wide range of applications. However, the different reflectivity of the measured object will affect the change of the received signal, resulting in different degrees of depth error in the system. In this paper, we analyze the influence of reflectivity on the system, establish the reflectivity-related error model, and propose the error calibration method. The proposed method estimates the approximate reflectivity of the measured object through the range and amplitude information output by the system at first, Then the parameters of the error curve model are changed according to the obtained reflectivity, and the corresponding compensation is obtained. This method can select the corresponding compensation amount for objects with different reflectivity. The experimental verification shows that the method in this paper has a good effect on the calibration of reflectivity-related errors.",
