A system that simultaneously prints digital image files' images and image files' internal metadata. The details for a digital image may be printed onto the front side and / or back side of a picture's printed hardcopy while simultaneously printing the digital image file's internal metadata or simultaneously displaying the digital image with its file's internal metadata on electronic media such as televisions, desktop, laptop and tablet computer screens, digital picture frames, cell phone, smart phone and telephone displays, public billboards, Internet web pages and x-ray photographs. The digital picture's details, being presented in the subject system as a file's internal metadata, include but are not limited to the picture's file name, the photographer's name, a copyright holder's name and a description of the picture, as well as the picture's technical details such as its image format, date, GPS location, focusing mode, metering mode, shutter speed, flash exposure compensation, resolution, ISO sensitivity, white balance, etc. A unique image identification code, password protection and encryption, can be assigned to each image and incorporated in the image file's internal metadata.

The invention discloses a photography measurement method for scene of a traffic accident based on a multi-activity control system. The method comprises the following steps: designing a semi-cone activity control system with a smaller upper part and larger lower part; (2) arranging a plurality of (m) activity control systems on the scene of the traffic accident, and photographing digital pictures from various angles; (3) respectively calculating the m activity control systems in the pictures, thus obtaining straight linear conversion parameters, distortion coefficients and inner and outer orientation elements corresponding to the m activity control systems; (4) wholly calculating the m activity control systems in the pictures, thus respectively obtaining m straight linear conversion parameters, the agreed inner orientation elements and the distortion coefficients; and (5) selecting two pictures to form a three-dimensional pixel pair, selecting the same activity control systems, and calculating the three-dimensional coordinates of target points.
