The invention discloses a method for measuring the CCD (Charge Coupled Device) chip dark current and double temperature constant. The method is realized by the following steps of: arranging a CCD chip in a dewar flask temperature control room, and configuring a reference temperature such that the CCD chip works at the reference temperature, wherein the temperature control room is sealed and light-proof; controlling the CCD chip to shoot an image through a control circuit, and uploading the information of the image to a computer; calculating an average gray value of the obtained image; drawing a fitting curve by utilizing the average gray value of the image and corresponding integration time to obtain a dark current; and finally calculating the double temperature constant by measuring the dark current at a plurality of different temperatures. The method disclosed by the invention has the advantages of high parameter measurement precision and good stability, and is suitable for precise measurement of the dark current and the double temperature constant of the CCD chip.
