Problems solved by technology

Most of the current projection correction software can only perform splicing and fusion under the condition of knowing the location of the projector, and the best location of the projector can only be determined by the experience of the operator, which has extremely high requirements for the operator and cannot Guaranteed optimal deployment every time

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0037] According to the actual projection requirements, the present invention proposes an evaluation index for judging the projection effect. Under the condition of the known number of projectors and the shape of the projection screen, according to the coverage area of ​​each projector set by the user, the projectors that affect the actual projection effect are used. Factors such as resolution, resolution difference rate, and projection distance difference are used as evaluation criteria. Under the condition of specifying the projection area of ​​each projector, the pose (position and orientation) of each projector and the screen that makes the overall projection resolution the highest is calculated. In order to obtain the best display effect, it also provides a useful reference for users to actually place the projector on site.

Abstract

The invention provides a multi-projector optimized deployment method realizing high-immersion projection. The method comprises specific steps as follows: step one, an initial pose of each projector is set, and a screen projection area is designated for each projector; step two, corresponding influence factors of each projector are calculated and comprise the projection resolution, the resolution difference and the projection distance difference; step three, a projection evaluation function is calculated according to the influence factors solved in the step two; step four, the pose of each projector is updated, the step two and the step three are repeated, the corresponding projection evaluation function of each pose is calculated, and the pose corresponding to the minimum projection evaluation function is determined as the pose of the projector. According to the method, the factors such as the projector resolution, the resolution difference rate, the projection distance difference and the like influencing the actual projection effect are taken as evaluation standards to build the evaluation function, the projector pose corresponding to the minimum evaluation function is selected as the optimized pose, the optimized deployment of the projectors is realized, and the optimal projection effect is achieved.

Description

technical field [0001] The invention relates to a high-immersion projection multi-projector optimal deployment method, which is suitable for high-immersion display, digital simulation, virtual reality and other technical fields. Background technique [0002] Since the projector is not an ideal optical imaging device, its actual projection effect is affected by its own performance and deployment location. Most of the current projection correction software can only perform splicing and fusion under the condition of knowing the location of the projector, and the best location of the projector can only be determined by the experience of the operator, which has extremely high requirements for the operator and cannot Guaranteed optimal deployment every time.
