Beam Projection Apparatus Automatic Screen Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beam projection apparatuses require manual adjustment for direction and focus, and can only display images on white screens, lacking the ability to automatically select suitable screens or correct image distortion.
Innovation Solution
A beam projection apparatus with an actuator module, beam projector, and control module that automatically searches for and selects a suitable plane in the surrounding structures, adjusts the direction and angle of image beams, and calibrates image focus and color to ensure accurate and distortion-free image display on non-white surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used for direction and focus, then the apparatus structure can be simple, but the ease of operation deteriorates
Solution Approach 1:
The system performs automatic screen detection, automatic positioning, automatic focus adjustment, and automatic color calibration without user intervention. The control module autonomously searches for surrounding structures, selects suitable planes, adjusts the actuator module for optimal positioning, and calibrates image parameters based on detected screen conditions.
Solution Approach 2:
The system uses a camera to detect the projected image on the screen and feeds this information back to the control module. Based on the feedback regarding image quality, position, and color accuracy, the control module automatically adjusts the actuator module positioning and projector parameters to optimize image display.
2Adaptability or versatility
If the apparatus can only display on white screens, then the device complexity is low, but the adaptability deteriorates
Solution Approach 1:
The system detects the color characteristics of the screen surface and automatically adjusts color calibration parameters to compensate for non-white backgrounds. The control module modifies image color parameters based on the detected screen color, enabling accurate image display on screens of various colors without requiring hardware changes.
3Ease of operation
If automatic screen search and selection is implemented, then the ease of operation improves, but the loss of time increases
Solution Approach 1:
The system performs preliminary scanning of the surrounding environment to detect potential screen surfaces before actual image projection begins. The control module uses the camera to pre-identify suitable planes and their characteristics, so that when projection starts, the positioning and adjustment process is already optimized, reducing the overall time required.
