1Area of moving object
If a single camera sensor is rotated to capture panoramic images, then the field of view is increased, but the image quality deteriorates due to distortions and poor resolution
Solution Approach 1:
The system divides the panoramic capture task into multiple segments by using multiple fixed camera sensors positioned at different locations, each capturing a specific portion of the scene. This segmentation allows each sensor to maintain optimal image quality while collectively providing a wide field of view, avoiding the distortions caused by rotating a single sensor.
Solution Approach 2:
The system merges the outputs of multiple camera sensors through image stitching algorithms to create a single panoramic image. By combining data from multiple fixed sensors rather than rotating one sensor, the system achieves both wide field of view and high image quality, as each sensor captures its portion without rotational distortion.
2Manufacturing precision
If multiple camera sensors are used to increase field of view, then image quality improves, but device complexity increases
Solution Approach 1:
The system employs a universal processing unit that handles multiple functions including image capture from multiple sensors, image stitching, distortion correction, and panoramic image generation. This multi-functional approach consolidates complexity into a single processing system rather than requiring separate dedicated components for each function.
Solution Approach 2:
The system introduces an intermediary processing layer between the multiple camera sensors and the final panoramic output. This intermediary layer manages the complexity by coordinating multiple sensor inputs, applying consistent processing algorithms, and generating unified panoramic images, thereby simplifying the overall system architecture.
3Speed
If video processing is performed in real-time, then responsiveness improves, but processing latency increases
Solution Approach 1:
The system performs preliminary processing actions by pre-configuring processing parameters, pre-loading necessary software modules, and establishing processing pipelines before actual video capture begins. This preliminary preparation enables faster real-time processing by avoiding delays in setup and configuration during actual video operations.
