Detection method and device for tempered glass spontaneous explosion source

The invention belongs to the technical field of material detection, and particularly relates to a detection method and device for a tempered glass spontaneous explosion source. Two point light sourcesirradiate glass, if the glass contains a defect, two spots are projected, the two spots are shot to obtain a picture, the picture is subjected to image processing to obtain plane coordinates of the centers of the two spots, and the position of the defect in the thickness direction of the glass is calculated according to the distance between the centers of the two spots; and when the defect is located in the range of 25-75% in the thickness direction of the glass, the defect is shot to obtain a picture, image processing is carried out on the picture, the type of the defect is judged accordingto an image processing result, and the glass containing the defect is marked when the type of the defect is heterogeneous particles. When the glass moves, whether the glass contains a spontaneous explosion source causing spont
