Panoramic Photographing Layout for Uniform Diffuse Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panoramic camera systems face challenges in achieving uniform lighting and optimal image capture due to direct illumination and non-uniform light distribution, leading to distorted colors and suboptimal imaging effects.
Innovation Solution
A photographing apparatus with a housing, lighting unit, guide rail unit, and control unit that includes a light shielding plate, adjustable bracket with a stepper motor, and a control system to adjust light intensity and position, ensuring diffuse reflection and uniform light distribution through a combination of white and gray coatings, and a rotary turntable for panoramic capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If direct illumination is used for photographing, then lighting intensity is sufficient, but light distribution becomes non-uniform causing distorted colors and poor imaging effects
Solution Approach 1:
The patent introduces a light guiding plate as an intermediary between the light source and the object to be photographed. The light guiding plate receives light from the lighting lamp and guides it to illuminate the object uniformly, preventing direct illumination while maintaining sufficient lighting intensity and achieving uniform light distribution for high-quality imaging
Solution Approach 2:
The patent changes the physical state and optical parameters of light through the light guiding plate. The plate transforms direct light into diffused light, changing the direction, intensity distribution, and uniformity parameters of illumination to eliminate color distortion and improve imaging quality
2Adaptability or versatility
If panoramic imaging is achieved using multiple lens assemblies, then viewing angle coverage is improved, but device complexity increases
Solution Approach 1:
The patent segments the panoramic imaging function into two parts: a single photographing device captures images from different positions along the guide rail, while the control unit segments the control tasks by automatically adjusting the bracket position and coordinating the photographing process, thereby achieving panoramic coverage without requiring multiple lens assemblies
Solution Approach 2:
The patent transitions from a multi-lens spatial arrangement to a single-lens multi-position approach. By moving the photographing device along the guide rail in one dimension, the system achieves panoramic coverage that would traditionally require multiple lenses arranged in different spatial dimensions, thus reducing device complexity
