3D holographic stereo projection technology is becoming more and more mature, and it is transitioning from various professional display platforms to practical applications. Common 3D holographic imaging is divided into:180,270,360. 180 is suitable for single-sided display, and is generally applied to stage holographic projection with large 3D imaging area, which can realize interaction. 360 can project the image in the real air, with a strong sense of depth, and the audience can watch it from any angle. Generally speaking, holographic transparent film or semitransparent holographic film technology is used in the stage of frame theater, and phantom imaging technology can also be used for local use in stage performance. It should be noted that in the stage performance, no matter what kind of 3D holographic projection is adopted, more stringent requirements will be put forward for the control of stage lighting. Due to the particularity of the working principle of 3D holographic projection video, it is necessary to coordinate and adjust the stage lighting in order to ensure the visual effect of 3D holographic projection when using 3D holographic video projection technology. Behind the holographic transparent film projection screen or on the side of the 3D phantom imaging video, the light distribution in the performance area of stage actors must avoid the 3D holographic projection video image. It is best to use computer lights or LED imaging lights with cutting imaging function, strictly control the projection range of stage lights in the actor's performance area, and never irradiate or reflect on the 3D holographic projection video, otherwise the quality of 3D holographic images will be seriously affected or disappeared; At the same time, these two lamps can not only conveniently control the light projection area, but also conveniently adjust the light projection tone, so that the light tone in the performance area is highly consistent with the tone of the 3D holographic projection video image. With the continuous progress of technology, 3D holographic projection technology has become more and more popular. The key of three-dimensional holographic projection in artistic production lies in its reasonable application in stage performance. Advanced and novel technology can bring wonderful visual experience and impact to the audience, but we should avoid simply showing off technology, usurp the role of the host, play the role of the finishing touch in the performance and serve the needs of artistic performance.
