Embodiment Construction
[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0023] The present invention is based on the narrow and long characteristics of the line expression, and based on the actual needs that visitors usually perform dynamic roaming observation from both sides or directly above the line. For the three-dimensional scene model of the same line, two roaming navigation cameras are set from both sides, and two cameras The synchronous observation posture of the two wings that maintains the alignment position is controlled by the program to realize the real-time expression of the line. Each camera projection screen constitutes an independent window, and the two windows can be output to two projectors through different video ports to realize the line alignment. For the holographic expression of the two wings of a large scene, two windows can also be output on the same viewport, and a projector can realize the...

The invention relates to a method for generating holographic roaming projection sources on two sides of a three-dimensional circuit in real time. The method comprises the steps of 1, respectively building projection windows on left and right sides of the circuit and setting respective projection virtual cameras in a circuit three-dimensional projection program, wherein the virtual camera corresponding to the activated window is called as an active camera, the virtual camera corresponding to the other window is called as a passive camera, and building a linkage relation between the active camera and the passive camera, thus achieving the purpose of synchronously controlling images of all window scenes by adjusting the parameter of the active camera; 2, determining a constraint relation between the interaction active camera on the currently activated window and the passive camera on the other window; and 3, computing yaw angles, roll angles and pitch angles of the left virtual camera and the right virtual camera. According to the method provided by the invention, the real-time and interactively controllable projection video sources can be provided for circuit-based holographic roaming projection devices on the two sides. The method can be applied to generating the holographic roaming projection video sources of highways, railways and other substances such as power lines and rivers.
Description
technical field [0001] The invention relates to the technical field of holographic projection, in particular to a method for generating a holographic roaming projection source on two wings of a three-dimensional line in real time. Background technique [0002] The traditional projection source used for holographic projection is to set up different camcorders on different sides around the model. When the model changes, each camcorder records a piece of synchronous film source, and then uses the video synthesis software to combine multiple The film sources from two sides are synthesized into one projection film source by frame, and the synchronous projection expression of multiple sides is realized through one projector. This kind of film source generation method requires synchronous recording in advance and artificial synthesis. Once synthesized, the film cannot be achieved in real time, nor can it realize the interaction with the scene. Contents of the invention [0003] ...
