Vehicle Surroundings Positioning via Gesture-Based Image Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing position data in a vehicle's surroundings often lack accuracy, making it difficult to describe specific locations, especially when traditional methods like street and house numbers are insufficient, and GPS signals may not be available.
Innovation Solution
The method employs an environmental sensor system to generate an image sequence, recognize a person's gesture, and identify points or areas within the sequence, generating position data that can be transmitted to a receiving device, allowing for precise location definition without requiring a separate position determination system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS or conventional navigation systems are used to determine position, then position data can be obtained, but the accuracy is insufficient to define precise locations such as parking spaces
Solution Approach 1:
The patent combines the environmental sensor system (camera) with the position determination function. Instead of using separate GPS equipment, the system merges image capture and position analysis into a single integrated approach, where the vehicle's existing camera records images and a computing unit extracts position data from these images, achieving high precision without additional complex positioning hardware
Solution Approach 2:
The patent introduces image data as an intermediary between the environment and position determination. Rather than directly measuring position with GPS, the system uses captured images as an intermediate representation, from which position coordinates are derived through image processing and feature recognition, enabling precise location definition without conventional positioning systems
2Measurement precision
If environmental sensor systems are used to capture images and determine position, then position accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent makes the environmental sensor system (camera) multi-functional by using it not only for its primary purpose (capturing images of surroundings) but also for position determination. The same camera that records environmental data is repurposed to extract position information, eliminating the need for separate positioning sensors and reducing overall system complexity while maintaining high accuracy
Solution Approach 2:
The system uses its own environmental sensor data to determine its position without requiring external positioning infrastructure. The vehicle's camera captures images that contain positional information, and the computing unit processes these self-generated images to extract position coordinates, making the system self-sufficient and avoiding dependence on GPS or other external positioning systems
3Ease of operation
If gesture recognition is used to identify location points, then ease of operation is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent implements feedback by displaying the recognized gesture and identified position back to the user through the user interface. The system processes the gesture, determines the position, and then presents this information to the user for verification, allowing the user to confirm or correct the interpretation. This feedback loop simplifies operation by making the system's understanding transparent and correctable
