Description

The utility model relates to photographic equipment and can be used in forensics and forensic medicine to determine the boundaries of a frame when remotely photographing objects with one frame from above.

In forensics and forensic medicine, one of the problems of fixing the scene is the inability to take a single shot from above to photograph an object, for example, a corpse with nearby space. In addition, in hard-to-reach places, such as under vehicles, wells, pipelines, in buildings and structures after an explosion, etc., it is not possible to fix individual objects in the usual way.

A well-known sight for the camera (AS USSR No. 1105478, publ. 1984.07.30, bull. No. 28), designed to determine the boundaries of photography and consists of a housing, a light source, an optical system that forms a label of the frame borders in the aiming plane of the camera. Marks of the frame boundaries are made in the form of identical lenses fixed at the front of the housing at distances from each other proportional to the size of the frame, with the light source mounted on the rear wall of the housing at the intersection of the optical lenses on a segment along the optical axis equal to the focal length of the lens. In order to ensure the sight when shooting with interchangeable lenses, the sight is equipped with a mechanism for proportionally changing the distance between the lenses. The camera is mounted on a telescopic holder (tripod).

The disadvantages of this device include the presence of parallax, due to the spatial separation of the optical axes of the lens and the viewfinder, as a result of which the photographed space, indicated by light marks, does not correspond to the completely received photo image on the negative, as well as the need to adjust the position of the sight before each photograph. In addition, in the daytime during sunny weather, light marks are practically invisible.

The closest in essence to the proposed technical solution is the sight for determining the boundaries when photographing objects from above (RU No. 40466 publ. 2004.09.10), which contains a board made of organic glass with a hole for the lens, a metal ring that fixes the board in a threaded connection for a filter camera lens. On the board at the same distance from the axis of the lens are four holders of ball bearings and

switch. In ball bearings, consisting of two hemispheres, light pointers are placed.

The disadvantage of this technical solution is the impossibility of using it when photographing with digital cameras without removable lenses, and the device does not provide the orientation of the camera so that the optical axis of the lens was exactly vertical when shooting the plan, it is impossible to use the specified digital optics for remote photography in hard-to-reach places.

The objective of the proposed technical solution is to create a visor for digital cameras, for example, for an OLYMPUS C-480 ZOOM digital camera and other similar in design, the technical characteristics of which do not include removable lenses, which have a simple design that allows you to accurately sight any objects and photograph them from above in one frame, while the optical axis of the lens when shooting the plan would be strictly vertical.

The problem is solved with the help of a visor to digital cameras containing a board made of organic glass, on the board at the same distance from the axis of the lens holders of ball bearings are mounted in which light pointers are installed, and the device contains a l-shaped suspension with a power supply for light pointers, which fixes the board on the camera, as well as on the L-shaped suspension, a rotary unit is installed, in which a rod is fixed at the opposite end of which a ball fixing unit with lescopic holder.

Distinctive features of the proposed utility model are:

- a rod with a spherical fixing block, allows you to set the required angle relative to the telescopic holder, and also allow the device to balance in the spherical fixing block and become strictly vertical relative to the ground, while the camera becomes strictly horizontal relative to the subject;

- a rotary unit, allows you to deploy the camera at the desired angle;

- L-shaped suspension, on which a power supply for light pointers and a rotary unit for orienting the device above the subject are installed.

Due to the listed features, the optical axis of the camera lens during shooting the plan remains strictly vertical, which allows you to accurately sight objects and photograph them from above in one frame using digital optics for remote photography in hard-to-reach places.

The proposed utility model is illustrated by the following drawings:

Figure 1 is a General view of the front panel of the camera.

Figure 2 is a side view of the device.

The visor to the digital camera consists of a front panel 1 with an opening 2, four panels are fixed on the panel: four racks with ball joints 3 in which four light pointers 4 are held, screw 5 for fixing the camera 6, L-shaped suspension 7 with power supply unit 8 for light pointers 4 and a rotary unit 9, in which the rod 10 is fixed, at the other end of which a ball fixing block 11 is mounted, in which the telescopic holder 12 is fixed.

An example of using the proposed device.

The device is set up in advance once to a specific camera. Before photographing objects, the product is removed from the packaging and the camera 6 is fixed on it with a screw 6. Then the telescopic holder 12 is extended to the required length, the power supply unit 8 is turned on, the shutter release delay mechanism of the camera 6 is turned on, the device is lifted above the subject, while the device is under its own weight , balancing in the ball fixing block 11 on the rod 10, it becomes strictly vertical relative to the ground, and the camera 6 is strictly horizontal relative to the subject. The delay mechanism is triggered, the camera photographs the object.

If necessary, deploy the camera at the required angle, act on the rotary unit 9. If necessary, photograph objects in hard-to-reach places, for example, under a car, the rod 10 is positioned at the required angle relative to the telescopic holder 12, and fix it in the ball fixing block 11.

As a result of using the proposed technical solution, simple in design, constantly ready to work in the field in hard-to-reach places, it becomes possible to accurately sight the object and photograph it from above in one shot.
