Abstract
A photograph assistance device for assisting a stationary camera in photographing a curved surface of cylindrical objects, such as a finger print wrapped around a bullet casing or soda can. The cylindrical object is moved at a constant speed into a photograph area of the camera while rotated at a constant rotating speed. The moving speed of the object is preferably determined so that the object can successfully pass through the photograph area of the camera while the camera and stop is adjusted for a small diameter opening for the best depth of field. The rotating speed of the object is preferably determined so that the image of the object can be rotated onto the field without producing a distorted image, that is, a stretched or compressed image.
Claims15
An apparatus for assisting a stationary camera in photographing a curved surface of an object, said apparatus comprising:
- rotary means, coupled to the object, for rotating the object around a predetermined axis;
- and
- mobile means, coupled to said rotary means, for moving said rotary means along a line perpendicular to said predetermined axis, whereby the object rotated by said rotary means can pass through a photograph area of the camera within an exposure time of the camera.
The apparatus according to claim 8, wherein said driving means comprises a spring biased hydraulic motor.
A photograph system for photographing a curved surface of an object comprising:
- a stationary camera;
- and
- an apparatus, optically coupled to said camera, for assisting said camera in photographing the curved surface of the object, said apparatus including:
- rotary means, coupled to the object, for rotating the object around a predetermined axis;
- and
- mobile means, coupled to said rotary means, for moving said rotary means along a line perpendicular to said predetermined axis, whereby the object rotated by said rotary means can pass through a photograph area of said camera within an exposure time of said camera.
