The invention discloses a method for measuring the carbon content of a solid catalyst based on a gray mode, which comprises the following steps of: firstly, establishing a standard curve by using known catalyst standard samples with different carbon content gradients and corresponding gray average values so as to fix the carbon content of all gray standard color cards; re-establishing a standard curve of the gray average value and the carbon content by using the gray average value of all gray standard color cards in each photo and the fixed carbon content; and finally, substituting the gray average value of the to-be-detected catalyst standard sample into the newly established relation equation of the gray average value and the carbon content standard curve to obtain the carbon content of the to-be-detected catalyst sample. When the carbon content of the catalyst sample to be measured is measured, the ambient light does not need to be corrected, the interference of the ambient light is avoided, the same imagi
