Projection Device Automatic Shade Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices require manual adjustment when a projection shade is present within their range, making operation inconvenient.
Innovation Solution
A method and apparatus that utilize a projection device with a projecting module, first and second imaging modules, and a position adjusting module to identify the presence of a projection shade and calculate necessary adjustments to move the device out of the shade's range, allowing for automatic adjustment without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projection device is fixedly placed, then the device structure is simple, but when a projection shade is present within the projection range, manual readjustment is required making operation inconvenient
Solution Approach 1:
The projection device incorporates a movable platform with motors that enable dynamic position adjustment in multiple directions (forward, backward, left, right) and rotation, transforming the previously fixed structure into a dynamic one that can automatically adapt to different projection environments and avoid projection shades
Solution Approach 2:
The system uses imaging modules to capture images of the projection range, automatically identifies projection shades through image processing, calculates the required adjustment parameters, and controls the position adjusting module to move the projection device accordingly, enabling the device to self-adjust without manual intervention
2Reliability
If manual readjustment is performed when projection shade is detected, then the projection picture can be optimized, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The system employs imaging modules to continuously monitor the projection range, processes the captured images to detect projection shades, and uses this feedback information to automatically control the position adjusting module, creating a closed-loop control system that ensures projection picture quality without manual intervention
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automated control system that uses image processing algorithms to identify projection shades and motor-driven mechanisms to execute position adjustments, substituting human operation with automated mechanical control

AI summary
A method for adjusting a projection picture includes: receiving a first image, captured by a first imaging module, of a position where the projection picture is located, and a second image, captured by a second imaging module, of surroundings of a projection device; identifying, based on the first image, whether a projection shade is present within a projection range of a projecting module; identifying position information of a projection shade in response to the projection shade being present; identifying, based on the second image, movable directions and movable distances of the projection device; and controlling, based on the position information of the projection shade and the movable directions of the projection device and the movable distances in the movable directions, the position adjusting module to adjust the projection device, such that the projection device escapes from the projection shade and a complete projection picture is acquired.
