Description

Single-lens banner prism stereo spectroscope

Technical Field

The utility model relates to a photographic appurtenance field of making a video recording, in particular to three-dimensional spectroscope of single-lens banner prism.

Background

The lack of stereoscopic display content is a bottleneck limiting the development of the stereoscopic industry. The contents of the stereoscopic display mainly originate from stereoscopic shooting, so that the popularization of the stereoscopic shooting method is especially important and urgent.

At present, three methods are generally available for binocular stereo shooting. The first method is stereo camera shooting, such as fuji W3 stereo camera, sony TD30 stereo camera, and the like. The stereo body has double lenses, can shoot dynamic images and is simple to operate. However, the double mirrors are close to each other, and are not suitable for long-distance large-scene shooting. In addition, the new products have poor image quality and cannot meet the due requirements, so that the production is stopped at present. The second method is dual-camera shooting, which requires dual-camera frames with a high price and can adjust the distance between the two mirrors within a certain range. The double frames are divided into a horizontal double frame and a vertical double frame, the distance between the double mirrors of the horizontal double frame and the vertical double frame is large, and long-distance shooting can be carried out; the distance between the two mirrors of the second lens is relatively small, and middle-distance shooting can be performed. However, in any mode, the dual-machine is required to keep synchronization in aspects of shutter, focal length, aperture, color, exposure, sensitivity, etc., and the adjustment is troublesome, which is not easy for an ordinary person to operate and drive. Of particular importance is shutter synchronization, which also requires the use of specially made synchronized shutter releases. The third method is single-machine translation shooting, and after a picture is shot by using a common camera, the picture is horizontally moved for a certain distance and then another picture is shot. However, this method cannot capture a moving image, and has a serious problem of synchronization with respect to the moving image.

The single-lens stereo additional lens on the market is not rare at present, but has the following defects: firstly, the pixel loss or the frame loss is serious; secondly, the final images are vertical left and right, which is not in accordance with the structure of a banner display in reality; thirdly, the volume is large and the carrying is inconvenient. Therefore, the products are not accepted by the market and have low market popularization rate.
