Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panoramic camera systems face challenges in achieving uniform lighting and optimal imaging conditions for capturing high-quality panoramic images, as they often rely on direct illumination which can distort colors and result in inconsistent light distribution.
Innovation Solution
A photographing apparatus comprising a housing with a lighting unit featuring a light shielding plate and a flexible lighting lamp, a guide rail unit with a stepper motor, and a control unit that adjusts light brightness and the position of the light shielding plate to ensure uniform light distribution, along with a rotary turntable and distance sensor for precise control and panoramic capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If direct illumination is used for photographing, then the lighting structure is simple, but the lighting uniformity deteriorates and color distortion occurs
Solution Approach 1:
A light diffusing plate is introduced as an intermediary component between the light source and the photographing scene. This plate diffuses the direct light into uniform scattered light, eliminating color distortion while maintaining lighting effectiveness. The diffusing plate serves as a mediator that transforms direct illumination into soft, uniform illumination without requiring complex multi-source lighting arrangements.
Solution Approach 2:
The lighting characteristics are changed by modifying the light propagation parameters through the diffusing plate. The plate changes the directionality and intensity distribution of light, transforming concentrated direct light into distributed diffuse light. This parameter change achieves uniform illumination across the photographing scene while keeping the lighting structure relatively simple.
2Device complexity
If the light shielding plate is fixed, then the structure is simple, but the adaptability to different object heights deteriorates
Solution Approach 1:
The light shielding plate is transformed from a fixed structure to a dynamically adjustable structure. The plate can move vertically along the side plate to adapt to different object heights, and its expansion/contraction capability allows it to adjust its shielding area dynamically. This dynamic adjustment mechanism enables the same structure to serve multiple photographing scenarios with varying object dimensions.
Solution Approach 2:
The light shielding plate is divided into multiple segments or sections that can expand and contract independently. This segmentation allows the plate to adjust its overall size and position flexibly, accommodating different object heights while maintaining structural integrity. The segmented design provides adaptability without requiring complete structural redesign for each height requirement.
3Device complexity
If the photographing device position is fixed, then the mounting structure is simple, but the positioning precision deteriorates
Solution Approach 1:
The manual or coarse mechanical positioning system is replaced with an automated motorized positioning system. A motor drives the photographing device along the guide rail, providing precise control over the device position. This mechanical substitution enables accurate positioning while maintaining relatively simple mounting structure through standardized motorized components.
Solution Approach 2:
A sensor is introduced to detect the position of the photographing device and provide feedback to the control system. This feedback mechanism enables precise positioning by continuously monitoring and adjusting the device location along the guide rail. The feedback loop ensures accurate positioning without requiring overly complex mechanical mounting structures.
