Camera Pose Detection and Auto Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often need to take multiple attempts to capture a satisfactory selfie as they may not be in the optimal pose during photographing, leading to increased complexity and potential disruption of their expression or pose when manually operating the camera.
Innovation Solution
A method and device for image photographing that automatically determine the device's orientation using a gravity sensor and detect if the target object's pose matches preset conditions, issuing prompts to ensure the object is in the correct position before automatically capturing the image, thereby reducing user operation complexity and improving image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual photographing operation is used, then user can control the photographing process, but user needs to make multiple attempts and operation complexity increases
Solution Approach 1:
The system automatically detects the user's pose, determines photographing conditions, and triggers photographing without manual intervention. The photographing device serves itself by autonomously monitoring conditions and executing the photographing action, eliminating the need for repeated manual attempts.
Solution Approach 2:
The system continuously monitors pose information and provides feedback to determine when photographing conditions are met. This feedback mechanism allows the system to automatically trigger photographing when the user achieves the desired pose, reducing the number of attempts needed.
2Ease of operation
If manual photographing operation is used, then user can control the photographing process, but user expression or pose may be disrupted
Solution Approach 1:
The system autonomously monitors pose conditions and triggers photographing without requiring manual operation. This eliminates the disruption caused by manual shutter pressing, allowing the user to maintain their natural expression and pose throughout the process.
Solution Approach 2:
The system performs preliminary monitoring of pose conditions before triggering the photographing action. By detecting and evaluating pose information in advance, the system ensures photographing occurs at the optimal moment without disrupting the user's natural state.
3Ease of operation
If automatic photographing is implemented, then operation complexity is reduced, but device complexity increases
Solution Approach 1:
The system integrates multiple functions including pose detection, condition determination, and photographing control into a single integrated system. This multi-functionality reduces the need for separate components and simplifies the overall device structure while maintaining automated capabilities.
Solution Approach 2:
The system combines pose monitoring, condition evaluation, and photographing trigger functions into a unified automated process. By merging these functions, the system reduces device complexity compared to having separate systems for each function while still providing comprehensive automated control.
4Measurement precision
If pose detection and automatic triggering is used, then photographing accuracy is improved, but system complexity increases
Solution Approach 1:
The system integrates pose detection and condition determination into a unified multi-functional module. This approach achieves precise pose measurement while avoiding the complexity of separate dedicated systems for each function.
