Multi-projector optimized deployment method realizing high-immersion projection

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.

[0003] The document "Fast high-resolution appearance editing using superimposed projections." ACM Transactions on Graphics (TOG) 31.2 (2012): 13. Discussed the relationship between the resolution, light efficiency and placement position of the projector, but it will The projector is regarded as an ideal optical device, so the damage to the projection quality caused by factors such as defocus blur and pixel size increase with distance increase in the actual projector are not considered
