Abstract: A time measurement correction method includes a field programmable gate array (FPGA) determining to enter a self-correction mode of time measurement, and in the self-correction mode, the FPGA controlling to generate a standard signal and the FPGA controlling to obtain the standard signal and collecting measurement data of at least one TDC channel included in the FPGA based on the standard signal. The standard signal is used to correct the at least one TDC channel of the FPGA.
