The invention discloses a pressure measurement method and device for a cavity model, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring a reference image and a test image sequence of a to-be-measured cavity model; mark points are determined in the reference image, and the reference position of each mark point in the reference image is obtained; performing target tracking on each mark point in the test image sequence to obtain a test position of each mark point in each test image; establishing a mapping relationship between the reference image and each test image according to the reference position and the test positions; registering the corresponding test image to the position of the reference image according to the mapping relation to obtain a registered test image sequence; and calculating according to the reference image and the registered test image sequence to obtain a pressure image sequence. According to the scheme, rapid and efficient large
