OmniPrior: A Multi-Prior-Guided Omnidirectional Representation of Dynamic Scenes in Overlapping Ultra-Wide
IEEE Transactions on Visualization and Computer Graphics
|June 15, 2026
Summary
OmniPrior captures dynamic scenes using multi-fisheye cameras, enabling realistic virtual reality and scene understanding. This Gaussian Splatting framework ensures physically consistent and temporally stable representations for novel view synthesis.
Area of Science:
- Computer Vision
- Computer Graphics
- Robotics
Background:
- Omnidirectional capture is crucial for immersive virtual reality (VR) and scene understanding.
- Outward-facing multi-fisheye camera rigs provide efficient full-scene coverage for dynamic environments.
- Existing dynamic scene modeling methods often overlook geometric and semantic priors in multi-fisheye data.
Purpose of the Study:
- To develop a novel framework for dynamic scene modeling using outward-facing multi-fisheye camera data.
- To leverage geometric and semantic priors inherent in multi-fisheye omnidirectional data.
- To create physically consistent and temporally stable dynamic scene representations.
Main Methods:
- Introduced OmniPrior, a Gaussian Splatting-based framework tailored for multi-fisheye omnidirectional capture.
- Incorporated metric-geometry-aware initialization and multi-prior guidance.
- Developed a dynamicness-aware Gaussian representation to encode object motion and temporal variations.
Main Results:
- Achieved effective novel view synthesis across new viewpoints and timestamps.
- Demonstrated physically consistent and temporally stable scene representations.
- Validated the method's effectiveness through extensive experiments.
Conclusions:
- OmniPrior effectively models dynamic scenes captured by multi-fisheye rigs, addressing limitations of existing methods.
- The framework enables high-quality novel view synthesis and realistic scene reconstruction.
- Learned representations support applications like 6DoF rendering and motion-freeze rendering.

Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
Fischer Projections
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...
Newman Projections
Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.

Relative Motion Analysis using Rotating Axes
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it instrumental in...

Orthogonal Trajectories
Orthogonal trajectories describe the geometric relationship between two families of curves that intersect each other at right angles. One illustrative case involves a family of parabolas that open sideways along the x-axis. These curves share a common shape but differ by a scaling parameter, resulting in a set of curves that all pass through the origin and widen at different rates.Determining Orthogonal TrajectoriesTo identify the orthogonal trajectories for these parabolas, the first step...
Inertial Frames of Reference
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with constant...
