Shooting Calibration for VR Image Size Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality shooting, the first target image shot by electronic equipment often fails to match the virtual background in head-mounted equipment, leading to a poor user experience due to size discrepancies between the two.
Innovation Solution
A shooting calibration method that adjusts the image size parameter of the first target image until it overlaps with the second target image observed through the wearable equipment, using an electronic equipment and a wearable equipment in communication, to obtain a target adjustment parameter for camera calibration, ensuring the image matches regardless of the camera's angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic equipment shoots a target image and removes background to synthesize with virtual background, then the VR shooting function is achieved, but the target image size does not match the virtual background size, resulting in poor user experience
Solution Approach 1:
The patent applies parameter changes by adjusting the image size parameter of the captured target image through iterative modification. The system changes the scaling parameter until the target image size matches the virtual background size, resolving the size mismatch problem while maintaining synthesis quality
Solution Approach 2:
The patent implements feedback by continuously comparing the target image with the virtual background, detecting whether they overlap properly, and using this feedback to adjust the image size parameter. This closed-loop process ensures accurate matching between real and virtual elements
2Reliability
If the first target image is adjusted to match the virtual background size, then the user experience is improved, but multiple iterations of adjustment are required, consuming time
Solution Approach 1:
The patent applies preliminary action by pre-establishing the coordinate system correspondence and shooting parameter relationships between the electronic equipment and wearable equipment. This preliminary calibration creates a foundation that reduces the number of iterative adjustments needed during actual shooting
Solution Approach 2:
The patent replaces manual iterative adjustment with an automated parameter adjustment mechanism. The system automatically modifies the image size parameter based on overlap detection, eliminating the need for manual intervention and reducing calibration time while maintaining matching quality

AI summary
Disclosed are a shooting calibration method, a system, an equipment and a storage medium. The shooting calibration method is applied to a shooting calibration system which includes an electronic equipment and a wearable equipment. The shooting calibration method includes: shooting, by the electronic equipment, a first target image, and sending the first target image to the wearable equipment; receiving, by the wearable equipment, the first target image sent by the electronic equipment; and in response to that the first target image does not overlap with a second target image observed through the wearable equipment, adjusting an image size parameter of the first target image, and returning to execute a step of sending the first target image to the wearable equipment until the first target image overlaps with the second target image, and obtaining a target adjustment parameter.
