Subnetting lattice, grid is square grid in the present embodiment.
Mode two: real imaging space is constructed；Real imaging space is divided by the certain components factor, obtains certain components
The real imaging space grid data packet of the factor.
It in the present embodiment, can be with if scanning the real imaging space of acquisition without scanning device or picture pick-up device
By constructing real imaging space, building one real imaging space identical with preset reality imaging space, same to Fig. 2-3 institute
Show, real imaging space is pressed into real imaging space and is divided by the certain components factor, obtains the reality imaging of the certain components factor

Frame output.This process will not cause hologram image to distort or lose.People can watch entirely in real imaging space
Object is ceased, when people is around real imaging space or when internal activity, holographic object is still defeated under the processing of Holographic Algorithm
It is normal out, and effect shakes.In embodiments of the present invention, image source data is not processed, therefore, by algorithm process speed
Degree is fast, can reach holographic real-time imaging.And existing image algorithm processing will generally locate in advance image source data in CPU
Reason, especially the higher image source data of resolution ratio is easier is delayed, and influences imaging effect.
Accident whether occurs and loses or be not achieved holographic sight for comparison virtual image space and real imaging space imaging
The effect seen, we compare multiple data check and test data comparison in the certain components factor, in virtual image sky
Between the certain components factor can be corresponded with the real imaging space certain components factor, while we are by a large amount of tests
Data result integration, the material object of similar holographic object is also placed on the position same with holographic object and tests hologram image by we
The accuracy and instantaneity of algorithm.It is as shown in Table 2-4:
The different cpu test operational efficiency of table 2
From table 2 it can be seen that different cpu tests, influence whether the operational efficiency of algorithm, it is higher that CPU configures more high efficiency.
The different display card test operational efficiency of table 3
From table 3 it can be seen that different display card tests: not interfering with the operational efficiency of algorithm.
The different memory difference video cards of table 4 cooperate test run efficiency
From table 4, it can be seen that different memory difference video card cooperation tests: not interfering with the operational efficiency of algorithm.
5 different content of table renders pressure test operational efficiency
As can be seen from Table 5, different content renders pressure test: rendering pressure influences whether more greatly rendering frame per second, will not
Influence the operational efficiency of algorithm.
