Background technique

Retaining photographic data plays an important role in plastic surgery work, for example, it is necessary to refer to photographic data in preoperative analysis, comparison before and after operation, experience exchange, publication of results, and evidence collection when disputes arise. Retaining photographic data is inseparable from a professional surgical clinical photography system. The existing surgical clinical photography system mainly includes cameras, light sources and background walls. The surgeon needs to correct the outline of the part, so at present, a ruler is still used for manual measurement, and the obtained data has large errors and lacks reference value.

In addition, even if the existing technology is used to take more standardized photos of the recipient, different plastic surgeons will obtain different plastic surgery results due to their own experience.

Detailed ways

The present invention will be described in detail below in conjunction with accompanying drawing:

As shown in Figures 1 and 2, the plastic photography system in this embodiment is mainly composed of a camera 50, a parallel light generating plate 10, and a photosensitive plate 20 parallel to and opposite to the parallel light generating plate 10. The middle part of the generating plate 10 is provided with a through hole, and the lens of the camera 50 is inserted into the through hole; the distance between the parallel light generating plate 10 and the photosensitive plate 20 is greater than 70 cm, so that the subject can be photographed The side of the parallel light generating board 10 includes a light emitting board 11 covered with LED lamp beads and a filter plate 12 covering the surface of the light emitting board 11, the filter plate 12 is composed of a horizontal polarizer 13 and a vertical polarizer 14 Composition: a plurality of two-dimensional PSD position sensitive detectors 21 are evenly distributed on the surface of the photosensitive plate 20; and a processor 30 signal-connected to the plurality of two-dimensional PSD position sensitive detectors is also included. When using the plastic photography system of the present invention to take pictures, the patient should stand between the parallel light generating plate 10 and the photosensitive plate 20, because the filter plate 12 can filter out the light rays that are not perpendicular to the light filter plate 12 incident, so that the light from the parallel light The light emitted by the generator plate 10 is parallel light, which can accurately display the contour shadow of the subject on the photosensitive plate 20, because the surface of the photosensitive plate 20 is spliced by multiple two-dimensional PSD position sensitive detectors 21 , the two-dimensional PSD position-sensitive detector can quickly upload the light intensity information to the processor 30 in the form of a signal, and the processor can quickly obtain the outline size of the subject through calculation, thereby solving the problem of the photographic system in the prior art The pictures taken are poor in reference and cannot give the technical problems of the outline size of the subject.

As a further improvement of the above technical solution, it also includes a rotary pedal 40, an axial thrust bearing 41 and a progressive motor 42 that drives the rotary pedal 40 to rotate are arranged below the rotary pedal 40, and the progressive motor 42 is connected to the processor 30 signal connections. Preferably, a rotating shaft 43 is arranged below the rotary pedal 40, and the rotating shaft 43 is arranged coaxially with the axial thrust bearing 41. The rotating shaft 43 is provided with a gear 44, and the gear 44 communicates with the gear through a transmission gear. Said progressive motor 42 transmission connection. Through the connection between the processor 30 and the computer, the doctor of photography can control the rotation angle of the rotary pedal 40 through the computer, and then obtain the contour size information of the subject at various angles in a short time.

As a further improvement of the above technical solution, the up, down, left and right positions of the parallel light generating plate 10 can be adjusted, so that the subject's body can be covered between the through hole and the photosensitive plate 20 .
