Embodiment Construction

[0023] In order to further understand the technical features and content of the present invention, the following detailed description will be given in conjunction with the accompanying drawings.

[0024] Such as Figure 1-3 Shown, this invention is a kind of three-dimensional film production method. The key to this method is that the axial distance is required when shooting, and the image distance is required for post-compositing.

[0025] When human eyes look at objects, there is not only the interpupillary distance between the two eyes, but also the eyes will converge on the observed object, and there is a dynamically changing convergence angle between the eyes.

[0026] The specific data of the interaxial distance is related to the model of the digital camera, the average interpupillary distance of human beings, the lens parameters, the set focal plane distance, and the projection size. Make the camera translate the axis distance value, and take two dual-viewpoint images....

Abstract

The invention discloses a production technology and method for three-dimensional films. The key point of the shooting and production method is that an axis spacing is required during shooting while an image spacing is required during post synthesis; dual sight point dislocation that occurs when human eyes look at an actual object is simulated by using an axis spacing formula and sight focusing of human eyes is simulated by using an image spacing formula; specific data of the axis spacing is related to parameters such as digital camera specifications, the average human pupil distance, lens parameters, specified focal plane distance, projection sizes and the like; and then the camera is translated for a distance of the axis spacing value and two dual sight point images are taken. For post synthesis, images on the left side of the left sight point image and images on the right side of the right sight point image are cut off by using software. A value is pixel number of the image spacing. Then left and right or upper and lower three-dimensional video files are synthesized, and then three-dimensional images are projected by using three-dimensional projection equipment. After a viewer wearing matched three-dimensional glasses, the left eye only sees left images while the right eye only sees right images, so that a three-dimensional watching effect is achieved.

Description

technical field [0001] The invention belongs to the field of three-dimensional film technology and animation technology, including shooting, production, projection and other technologies, and specifically relates to a production technology and method of a three-dimensional film. Background technique [0002] Under normal circumstances, a stereoscopic movie is to use two lenses such as human eyes to shoot dual-viewpoint images of the scene, and then through two projectors, the images of the two viewpoints are projected synchronously, so that the slightly different two pictures The image is displayed on the screen, so that the left eye can only see the picture reflected by the left machine, and the right eye can only see the picture reflected by the right machine, so that the stereoscopic image will be seen, which is the principle of the stereoscopic movie ( as attached figure 1 shown). [0003] The current stereoscopic photography shooting technology and stereoscopic film s...
