The invention discloses a test method for detonation velocity of a nonel with a defect. The test method is a non-contact test method characterized in that digital images are shot by utilizing a high-speed camera, the images are subject to digital processing by a CAD (Computer Aided Design) software of a computer so as to realize detonation velocity test of the nonel. According to the test method, the measured detonation velocity is closer to the instantaneous velocity of a measure point; the normal start of the high-speed camera in detonating moment of the nonel can be guaranteed, and the required whole process can be shot; the calculated amount is reduced, and the difficulty of data processing is lowered; the AUTO CAD software is introduced in data processing, and the distance can be more conveniently and accurately measured by utilizing a proportional scale function, a building block function, and a zoom in and out function in the CAD.
