Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras are used to achieve bullet time effect, then the shooting effect can be achieved, but the system complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple camera functions into a single panoramic camera that can capture 360-degree views. This single camera performs the function of multiple traditional cameras by rotating around the subject and capturing images from all directions, thereby reducing system complexity while maintaining the bullet time effect quality
Solution Approach 2:
The panoramic camera serves multiple functions: it captures images from all angles simultaneously, replaces the need for multiple fixed cameras, and provides flexible viewpoint control. This multi-functional device achieves the bullet time effect without requiring a complex array of specialized cameras
2Reliability
If multiple cameras are deployed around the shooting path, then the bullet time effect can be achieved, but the shooting cost increases
Solution Approach 1:
The patent merges the functionality of multiple expensive cameras into a single panoramic camera system. By using one camera that rotates to capture 360-degree views, the system eliminates the need to purchase, deploy, and maintain multiple cameras, thereby significantly reducing shooting costs while maintaining effect quality
Solution Approach 2:
The panoramic camera creates virtual copies of multiple camera perspectives through software processing. Instead of using physical multiple cameras, the system captures one panoramic image and generates multiple viewpoint images computationally, replacing expensive hardware with more economical software solutions
3Reliability
If traditional cameras are used to achieve bullet time effect, then the shooting effect can be obtained, but the shooting progress becomes slow
Solution Approach 1:
The panoramic camera captures continuous 360-degree views in a single shooting session, whereas traditional methods require multiple cameras positioned at different locations. This continuous capture approach eliminates the need for time-consuming camera repositioning and setup between shots, significantly improving shooting productivity
Solution Approach 2:
The panoramic camera pre-captures all possible viewpoints in a single 360-degree rotation around the subject. This preliminary comprehensive capture allows for flexible post-processing and viewpoint selection without requiring additional shooting sessions, thereby accelerating the overall shooting process

AI summary
Provided in the present invention are a method for achieving a bullet time capturing effect and a panoramic camera. The method comprises: acquiring a panoramic video captured when a panoramic camera rotates around a capture target; acquiring from within the panoramic video hemispherical images close to the side of the capture target; splicing the hemispherical images to generate a spliced image; and fixing a viewpoint of the spliced image, thus achieving a bullet time capturing effect. According to the present invention, only one panoramic camera is needed to be able to capture the bullet time capturing effect, so that the capturing cost of the bullet time capturing effect in the present invention is low. Meanwhile, since the bullet time capturing effect is obtained by means of a panoramic video being captured when a panoramic camera rotates around a capture target and processing being carried out on the panoramic video, the precision is high.
