Step 2 receives first environment sound and second environment sound, judges whether the characteristic parameter of first environment sound contains
Start information, if first environment sound includes starting information, first environment sound is determined as target sound and according to starting
Information starting projection then judges whether the characteristic parameter of second environment sound contains if first environment sound does not include starting information
There is starting information, if second environment sound includes starting information, second environment sound is determined as target sound and according to opening
Dynamic information starting projection, switches projecting direction according to the current location of target sound, and picture can be obtained and sound is matched vertical
Volumetric video can mostly be enjoyed per capita and be experienced in immersion.
As further embodiment of the embodiment of the present invention: light converting member includes reflection component, refractive component and polarization
Component, the light that can be projected to projector are reflected, reflected and are polarized, and the use demand of people is met.
As further embodiment of the embodiment of the present invention: being modeled in step 1 using KNN algorithm, KNN algorithm is several
According to one of simplest method in sorting technique of excavating.So-called K arest neighbors is exactly the meaning of k nearest neighbours, and what is said is every
A sample can be represented with its immediate k neighbour, and in doing anomalous identification, our iteration distances find out neighbours most
Few point, is defined as abnormal point.
As further embodiment of the embodiment of the present invention: the specific steps modeled in step 1 are as follows: be divided into projection screen
Multiple rectangle frames interlock contiguous concatenation formation lattice, using projector from multiple and different angles crawl lattice figure
As and projector is demarcated, recycle spin matrix and translation matrix to be converted, then corresponding correction.
As further embodiment of the embodiment of the present invention: further including the spy to three-dimensional video-frequency addition given category in step 2
Effect, fidelity are higher.
As further embodiment of the embodiment of the present invention: the special efficacy of given category include sound zoom, image amplification,
Discoloration, mobile, preposition plus light beam, Jia Jiejie, luminous, flash of light and animal jump out, and experience effect is more preferably.
As further embodiment of the embodiment of the present invention: the characteristic parameter of first environment sound and the spy of second environment sound
Levying parameter includes acoustic amplitudes and sound arrival time, can preferably determine the current location of target sound.
Compared with prior art, the beneficial effect of the embodiment of the present invention is:
The present invention has rational design, and the angle of every projector directive light converting member is determined by the position according to all parts
Degree, then switch projecting direction according to ambient sound, so that picture and sound matching degree are high, immersion experience is more preferable, use scope
Extensively.
