The aplication relates to a power supply voltage calibration device and a power supply voltage calibration method. The power supply voltage calibration method comprises the steps that the power supplyvoltage calibration device acquires a power supply voltage output by a power supply chip; and the power supply voltage calibration device generates a resistance value adjustment instruction accordingto the power supply voltage and a target power supply voltage and sends the resistance value adjustment instruction to a digital potentiometer of a power supply chip of a photoelectric detector, wherein the resistance value adjustment instruction is used for adjusting the resistance value of the digital potentiometer. According to the invention, a problem of inconsistent power supply voltage of the photoelectric detector caused by factors such as temperature change or power supply channel inconsistency is solved, and the power supply voltage consistency of the photoelectric detector is improved. 本申请涉及一种供电电压校准装置和供电电压校准
