The invention belongs to the technical field of water suspension granulation of press-fitting composite explosives, and discloses a method for safely monitoring the water suspension granulation process of the press-fitting composite explosives in a laboratory. According to the imaging principle that an object forms an upright, equal-size and equal-distance virtual image in the plane mirror, the plane mirror is stably arranged right above the reaction beaker through the cross clamp, and an included angle of 45 degrees is formed between the plane mirror and the horizontal plane, so that the object in the reaction beaker is just reflected to the mirror surface, and the plane mirror reflects the light to the camera lens, and therefore, the object in the reaction beaker is reflected to the camera lens. The camera can capture each frame of object image in the reaction beaker, so that human eyes are replaced by machine vision, and experimenters do not need to look down to observe the condition ...
