Problems solved by technology

If the projection surface or projection screen is deformed, the projection surface or projection screen needs to be strictly adjusted, or even replaced with a new projection surface or projection screen, which increases the cost of the multi-projection system and limits the application range of the multi-projection technology
[0004] If the projection surface or projection screen is a complex curved surface, different distortions and deformations will occur in the projection image and cannot meet the visual needs of the observer. Therefore, this project makes full use of the geometric shape information and observation point of the projection surface or projection screen to study A multi-channel intelligent projection technology for complex curved surfaces to ensure an ideal image on any complex projection surface or projection screen, reduce the cost of the projection system, improve the intelligence level of the projection system, and expand the application range of the projection system

Embodiment Construction

[0047] The adaptive projection system facing the irregular projection surface is characterized in that the required equipment and implementation steps of the system are as follows:

[0048] Required equipment: such as figure 1 As shown, a projector 1, a video camera 2, a computer 3 equipped with a dual-channel display card, and a hard connection bracket 4; wherein the projector 1 and the camera 2 are fixed on the hard connection bracket 4 so that the two remain relatively fixed, and the video camera The image acquisition output port of 2 is connected with the computer 3 through a cable, and the projector 1 is connected with the output port of the dual-channel display card in the computer 3 through a cable, so that the projector 1 is used as an extended desktop of the computer 3.

[0049] The implementation steps of the adaptive projection system for irregular surfaces are as follows:

[0050] 1. Calibrate the internal and external parameters of projector 1 and camera 2 by usi...

Abstract

The invention relates to an irregular surface-orientated self-adaptive projection system, and belongs to the technical field of computer image processing. The system comprises a self-adaptive projection device, adopts a projected image geometric correction method based on a geometrical shape with an irregular surface, and uses a novel colour structure optical encoding method, thus improving the interference-resistant capacity of an encoded image and increasing the reconfiguration speed of the irregular surface. By using the system, the rapid reconfiguration can be performed on the irregular surface, and the distortion correction can be performed on a projected image according to the reconfiguration result, so that an observer can observe the continuously consistent and undeformed projected image on the irregular surface, thus reducing the cost of the projection system, improving the intelligentization level of the projection system, and expanding the application range of the projection system.
