Description

Three-dimensional movie & TV shooting device

Technical Field

The invention relates to the technical field of film and television shooting, in particular to a three-dimensional film and television shooting device.

Background

With the progress and development of the film and television industry, the requirements of viewers on the film and television picture effect are higher and higher, and the stereoscopic film is more and more popular with the viewers. Two eyes of a person are separated by about 5 centimeters, and the person looks like the same thing, the angles of the two eyes have small difference and are transmitted into the brain through the retina to generate far and near depth, so that the stereoscopic impression is generated. According to this principle, a dual-lens camera is used to simulate the left and right eyes of a person, respectively. The same scene is shot simultaneously from two shot points located on the same horizontal line at the time of shooting, so that two pictures having horizontal parallax are obtained at two shots. When showing, the left and right frames are reflected on the same plane screen at the same time, and become the superimposed double-image frame. The left and right eyes of the audience respectively see the left and right pictures shot from the left and right lenses, so that the image presented in front of the eyes of the audience has a three-dimensional effect and brings people with a realistic sensation of being personally on the scene.

The stereo camera shooting requires at least two lenses and two photosensitive CCD or CMOS elements, and is used for taking images instead of two eyes of a human, the distance between the two lenses and the included angle and the distance between linear guide rails must imitate the actions of two eyeballs of the human eyes, and the distance between the lenses is continuously adjusted according to the distance change of a shot object, so that the visual difference of the two shot images is the same as the visual difference directly watched by the human eyes to the maximum extent.

At present, 3D shooting equipment is mainly divided into a single-machine double-lens camera and a double-machine double-lens camera. The single-unit double-lens camera is characterized in that two lenses are arranged in parallel at two opposite positions of a camera body. The double-camera double-lens camera means that two lenses respectively adopt one camera body, the two cameras are installed according to a certain angle and distance through a specific tripod head, and three-dimensional shooting is realized through unified parameter adjustment and synchronous shooting control.

The existing stereoscopic video shooting device in the industry is generally a single-machine double-camera, and because two lenses of the single-machine double-lens camera are fixed, the axial distance and the angle between the two lenses cannot be adjusted. Therefore, the single-camera dual-lens camera is generally used for shooting programs with low requirements on shooting quality, light and portable mobile shooting and low budget, and at present, no single-camera dual-lens camera suitable for shooting high-quality requirements is available.
