Description

Shooting method and application of three-dimensional animation photo

technical field

The invention relates to the field of photo shooting, in particular to a three-dimensional animation photo shooting method and its application.

Background technique

To make a three-dimensional animation presentation film, there must be photos taken from various angles, which are just three-dimensional animation photos. The present shooting method generally adopts a rotatable stand, and the subject is placed on the stand when shooting. The disadvantage of such a device and method is that it is inconvenient to place soft objects. Because soft objects are deformed after being placed, the photos taken are not real. Moreover, soft objects are not easy to place, and often the side you want to shoot cannot face the camera.

Contents of the invention

In order to overcome the defects of the prior art, the purpose of the present invention is to provide a method for shooting three-dimensional animation photos, which can accurately adjust the angle to ensure that the 360° angle of the object is evenly shot, and is especially suitable for shooting soft objects such as human bodies Three-dimensional animation photos of objects that are difficult to place horizontally and stably, such as tissue and organ specimens.

The three-dimensional animation photo shooting method of the present invention utilizes a three-dimensional animation photo shooting device;

The shooting device of the three-dimensional animation photo comprises a bracket, a suspension frame and a dial, the dial is horizontally fixed on the upper part of the bracket, and the shaft of the suspension frame is movably connected to the upper part of the bracket, passes through the central hole of the dial, and is located between the dial A pointer is arranged radially of the shaft on the top, and a suspension device for hanging the subject is arranged at the lower part of the suspension frame;

When shooting, hang the subject on the suspension device at the bottom of the suspension frame, turn the suspension frame so that the pointer is aligned with the scale line of the dial, and mark the scale line as the starting position, stop rotating, wait for the object to be photographed to be still,

Fix the camera position and shoot;

Then turn the hanger to make the pointer point to the next adjacent scale line of the dial, stop turning, wait for the subject to be still,

shoot;

According to the above method, proceed in sequence until the scale line before the initial position of the dial.

In the method of the present invention, it is preferable to fix the camera at the same position. This ensures uniformity in the quality of the shots.

In the method of the present invention, the camera preferably adopts a digital camera, and uses a continuous shooting function. In this way, you can choose a photo with the best effect at that time, so as to eliminate all kinds of interference. You know, the opportunity to shoot a relatively rare object is rare. For example, to take pictures of human tissue and organ specimens, it is necessary to travel thousands of miles to each cooperative unit to take pictures separately. If different cameras are used, different people take pictures at different distances, and the quality of the pictures taken is not uniform, the subsequent processing of the pictures will be difficult, and the animation effect produced in the future will not be good.

Such a device facilitates positioning of the subject, as well as controlling the subject's rotation. The suspension frame of the present invention makes the object to be photographed suspended, so that it is convenient to place soft objects. Rotating suspensions, dials and hands form the system for controlling the orientation of the subject. Rotating the subject can take pictures in different orientations, so as to take photos that meet the requirements of 3D animation.

Preferably in the present invention, each scale line of the dial is provided with a positioning hole for placing a positioning pin, inserting the positioning pin into the positioning hole, and rotating the suspension frame so that the pointer touches the positioning pin of the dial. The positioning pin is mainly used for rotating the suspension frame, and the pointer on the suspension frame shaft will touch the positioning pin, thereby ensuring the accuracy and consistency of the rotation angle. Considering the continuity of viewing and the workload of shooting, the scale interval on the dial should not be too large or too small, preferably 11.25°.

In this way, when shooting, insert the positioning pin into the positioning hole of the dial, and mark the positioning hole as the starting position; hang the subject on the suspension device at the lower part of the suspension frame, and turn the suspension frame so that the pointer touches the position of the dial. Locate the needle, stop rotating, wait for the subject to be still, and shoot according to the above method.

Afterwards, take out the positioning pin in the subject device, insert it into the next adjacent positioning hole of the dial, rotate the suspension frame so that the pointer touches the positioning pin of the dial, stop rotating, wait for the subject to be stationary, and then shoot according to the above method.

Proceed in sequence up to the pilot hole just before the starting position of the dial.

In order to better stabilize the object to be photographed, the present invention preferably uses two thin and soft metal wires to fasten two parts of the object to be photographed, and the other ends of the two thin and soft metal wires are respectively tied to two suspension parts of the suspension device. Thin soft metal wire is selected from copper wire, aluminum wire, iron wire. The soft metal wire is preferably copper wire. Because the copper wire has both sufficient strength and excellent bendability, and it does not rust and will not affect the specimen.

Another object of the present invention is to provide the application of the shooting method of three-dimensional animation photos in shooting human tissue and organ specimens.

The beneficial effects of the present invention are: the photographing method provided by the present invention can freely select the angle and direction of photographing, so that it is convenient to find the surface and point to be photographed. It can accurately and realistically shoot three-dimensional animation photos of the subject, especially suitable for shooting soft objects and irregularly shaped objects that are difficult to place horizontally and stably, such as shooting human tissue and organ specimens.
