The invention discloses a ray based photographing method, which comprises the following content: radioactive rays are placed at different directions of a photographed object; the radioactive rays penetrating through the photographed object are imaged by using a radioactive ray photographing plate; The radioactive rays are filed by using a radioactive ray filter before being imaged; an imaging image of the filtered radioactive rays is automatically detected by using an image detector after the radioactive rays are imaged; and automatic correction for the image is completed by using an image processor of a computer after image detection, and the startup of the next time of photographing is controlled. According to the invention, filtering, detection and correction processing are arranged before and after photographing imaging, so that the photographing quality is greatly improved. In addition, a switch of the photographing equipment stays at an initial state in the operations of image detection and correction, thus a phenomenon that server resources are always occupied because of certain time difference is reduced, the stability and effectiveness of each photographing operation are ensured, and the operability is high.
