The invention discloses an automatic laboratory radiometric calibration method based on a Jilin No.1 satellite and an evaluation method thereof, belongs to the technical field of image processing, and solves the problem of low data processing timeliness caused by high manual participation degree of existing laboratory radiometric calibration data. Traversing original data according to a Jilin No.1 satellite laboratory radiometric calibration data path; classifying the original data according to experiment names of Jilin No.1 satellite laboratory radiometric calibration; respectively outputting a Jilin No.1 satellite laboratory relative radiometric calibration coefficient and goodness of fit under each spectrum band and each imaging working condition according to responsivity experimental data; according to the repetitive experimental data, outputting repetitive indexes under each spectral band and each imaging working condition; respectively outputting indexes and goodness of fit of the line time linearity un
