Beschreibung
Zusammenfassung:	The embodiment of the invention provides a depth sensor calibration system and method. The system comprises a calibration processing module, a delay processing module, a depth sensor and a transmitting module. The calibration processing module determines a delay parameter value of the delay processing module according to a theoretical test distance and configures a delay parameter of the delay processing module according to the delay parameter value. The depth sensor is controlled to output a modulation signal to the delay processing module; a measurement distance obtained according to an echosignal is obtained and the measurement distance is calibrated based on the theoretical test distance. The delay processing module delays a modulation signal according to the delay parameter value configured by the calibration processing module and then outputs the modulation signal to the transmitting module. The transmitting module outputs a detection signal according to the modulation signal; and the depth sensor detec
