1) calibration of positional relationship should be consistent with 3D coordinate-system employed in special-shaped perspective plane 3Dization model data, i.e.,
Answer identical and according to the proportionate relationship between real world and special-shaped perspective plane 3Dization model data in the direction of tri- components of X, Y, Z
It converts, projector's installation site finally should be a space coordinate point, and the point is opposite with special-shaped perspective plane 3Dization model
Positional relationship should keep ratio consistent with projection device in real world with the relative positional relationship on special-shaped perspective plane；
2) mounting distance on the relatively special-shaped perspective plane of projection device according to real world and special-shaped perspective plane 3Dization model data it
Between proportionate relationship convert, principle back and forward；
3) angle of projection central axes should be 3 dimensional vectors, comprising projection central axes in space before
Into direction；
4) projection level angle should be converted in real world and be transformed into special-shaped perspective plane right above projection device
World coordinate system used by 3Dization model finally should be 3 dimensional vectors.
Fig. 6 is that 3D calculates procedure chart in real time, and with reference to Fig. 6, step 101 to 104 is arranged for basic data or collection process, can
It directly uses after the data for being arranged or collecting are saved for next, does not change after being provided with for the first time in related data
In the case where then without executing again.
Step 105:3D calculates process in real time, real-time for being carried out single or multiple videos or picture material by video card
3D calculation, and result is exported to projection device, this step includes following sub-step:

S1055: the perspective projection matrix of setting 3D program, in which:
1) y orientation angle should be consistent with camera lens used by projection device；
2) it indulges than projection device should be used to indulge ratio by the pixel that current lens can be projected effectively；
3) minimum-depth and depth capacity should be set as suitable value to ensure all it is desirable that the content obtained all can get.
S1056: scene set light source, light source vector are projection device central axes vector.
S1057: triangle each in special-shaped perspective plane 3D model is subjected to cutting, if being by each original triangle cutting
Dry small triangle.
S1058: establishing 3D World Scene, and the triangle after all cuttings is included coordinate points by this sub-step, catenation sequence,
UV coordinate is operated with normal vector write-in video memory for video card, should provide CPU operation permission to modify certain in the process of running
A little data are to realize certain special visual effects.
S1059: establishing data texturing corresponding with source serial number according to the video of input or image source and video memory be written, main
CPU operation permission should be provided so as to real-time update related data.
S10510: by motion information transformation model kinematic matrix, i.e. the world converts (WorldTransform) matrix,
In:
1) longitudinal movement corresponds to Y-axis displacement, and transverse movement corresponds to X-axis displacement, constitutes transposed matrix；
2) rotary motion corresponds to Z axis spin matrix；
3) comprehensive spin matrix and transposed matrix constitute the world and convert (WorldTransform) matrix, it should be noted that composition sequence
It is rear to be displaced first to rotate.
S10511: calculating data in GPU, illustrates by taking the D3D tinter process flow of standard as an example here:
1) VS or vertex Shader Stage realize world's transformation (WorldTransform) of standard, and camera transformation (also referred to as regards
Angular transformation, ViewTransform), perspective projection transformation (PerspectiveProjection)；
2) PS or pixel Shader Stage realize rasterisation, each pixel are filled into texture number corresponding with its source serial number
According to, wherein pay special attention to, normal vector and illumination calculation result answer inverted value, i.e., calculated result reflect weaker region should enhance and
It is not to weaken brightness, vice versa, to ensure necessary luminance balance；
3) other shader or tinter stage are without intervention, default.
It is more that this step is related to content, detailed process such as Fig. 6
Wherein S1058: 3D World Scene is established, S1059: is established according to the video of input or image source corresponding with source serial number
Data texturing and be written two step of video memory write data into video memory and meanwhile should be arranged CPU can operating right, S10510 construct mould
Type kinematic matrix realizes that the real-time synchronization of virtual 3d model and realistic model changes, by operating three module corresponding datas, i.e.,
Image can be achieved or video content synchronizes the function of being projected to motion model surface.
Step 105: control motion control device drives three motors, realizes the movement of projection model, and by related data
It is committed to S10510 module.
