Binocular Display Alignment Using Depth-Based Vertical Correction

The patent applies different correction strategies based on the depth location of virtual objects. For distant objects, aggressive correction is applied since they have less visual impact. For nearby objects, conservative correction is used to maintain image stability and avoid causing user discomfort. This local differentiation of correction intensity resolves the contradiction between achieving good fusion quality and minimizing discomfort.

The correction approach dynamically adjusts based on scene depth characteristics. The system continuously analyzes the depth distribution of virtual objects and adapts the correction magnitude accordingly. When objects are far away, larger corrections are applied; when objects are nearby, smaller corrections are applied. This dynamic adaptation allows the system to maintain fusion quality while minimizing noticeable disruptions that cause discomfort.

The patent implements depth-based differential correction where the correction magnitude is locally adapted to the depth of virtual objects. Distant objects receive stronger correction forces to achieve good fusion, while nearby objects receive weaker correction to maintain stability. This resolves the contradiction by applying aggression only where it won't cause noticeable disruption.

The system changes the correction parameter (magnitude of vertical adjustment) based on the depth parameter of virtual objects. By making the correction strength a function of object distance, the system achieves high fusion quality for distant objects while preserving image stability for nearby objects, thus resolving the contradiction between fusion quality and stability.

The patent applies conservative correction only to nearby virtual objects where stability is critical, while allowing more aggressive correction for distant objects where fusion quality is more important. This spatial differentiation resolves the contradiction by applying the appropriate correction intensity to the appropriate depth regions.

The correction magnitude dynamically varies with virtual object depth. The system transitions from conservative correction for nearby objects to aggressive correction for distant objects, optimizing both stability and fusion quality across different depth regions simultaneously, thus resolving the contradiction.

The patent segments the virtual scene into depth-based regions (near and far objects) and applies different correction strategies to each segment. This segmentation allows the system to achieve high overall performance by optimizing correction for each depth region independently, while keeping the computational approach modular and manageable.

The system uses depth distance as a parameter to control correction magnitude, creating a continuous or discrete correction profile. This parameter-based approach improves system performance by adapting to scene characteristics, while the computational complexity remains manageable through the use of simple depth comparisons and lookup tables or predefined correction curves.
