Virtual Effect Mounting Plane Detection Using Vanishing Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting a virtual effect mounting plane in images suffer from low detection accuracy and poor robustness due to reliance on gradient information of pixels, which leads to incomplete and inaccurate determination of mounting planes, especially in varying image scenarios.
Innovation Solution
The method involves extracting contour line segments and edge corner points to generate quadrilateral structural borders, using vanishing points to evaluate matching degrees, and determining a target border suitable for mounting virtual effects based on these criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gradient information of pixels is used to determine mounting plane, then the method is simple to implement, but detection accuracy and robustness deteriorate
Solution Approach 1:
The patent segments the contour detection process into multiple stages: first extracting contour line segments, then obtaining edge corner points, generating quadrilateral structural borders, and finally determining mounting planes through vanishing point matching. This segmentation allows each stage to focus on specific aspects, improving overall detection accuracy while maintaining implementation clarity.
Solution Approach 2:
The patent introduces vanishing points as an intermediary element to bridge the gap between contour extraction and mounting plane determination. By using vanishing points from multiple structural borders as intermediaries for matching and evaluation, the system achieves more accurate and robust mounting plane detection without directly relying on pixel gradient information alone.
2Ease of operation
If gradient information of pixels is used to determine mounting plane, then processing is straightforward, but robustness in different image scenarios deteriorates
Solution Approach 1:
The patent changes the key parameters from pixel gradient information to contour line segments, edge corner points, and vanishing points. This parameter transformation enables the system to maintain robustness across different image scenarios (such as various angles, distances, and object types) while keeping the processing workflow relatively simple and systematic.
Solution Approach 2:
The patent creates a universal mounting plane detection framework that can handle multiple image scenarios through a consistent process: extracting contours, identifying corner points, generating structural borders, and evaluating through vanishing point matching. This multi-functional approach allows the same algorithm to work across different object types and imaging conditions, improving robustness without significantly complicating the processing steps.

AI summary
Embodiments of the present disclosure provide a method for detecting a virtual effect mounting plane, an electronic device, and a storage medium, and the method includes: acquiring contour line segments, and obtaining corresponding edge corner points based on the contour line segments, in which the contour line segments represent a contour of an object in an image to be detected, and the edge corner points are intersection points between the contour line segments; generating at least two quadrilateral structural borders with the edge corner points, in which each of the structural borders represents a contour of a plane of an object in the image to be detected; and obtaining matching degrees of the structural borders through target vanishing points corresponding to the structural borders, and determining a target border based on the matching degrees.
