Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking guidance systems are inadequate, leading to difficulty in finding vacant parking spaces and inefficient use of parking lots, with users often driving blindly and passively receiving inaccurate information.
Innovation Solution
A navigation system utilizing cameras to detect vacant parking spaces, determine vehicle location, and generate navigation routes to these spaces, incorporating real-time obstacle detection and reservation mechanisms to optimize parking lot utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional guidance plates and indicating lights are used to show vacant parking spaces, then the system structure is simple, but the user cannot obtain accurate real-time information and must drive blindly to find parking spaces
Solution Approach 1:
The patent replaces traditional mechanical guidance systems (guidance plates and indicating lights) with a vision-based positioning system using cameras and image processing algorithms. The server captures images from multiple cameras, processes them to identify vacant parking spaces and vehicle locations, and provides accurate navigation guidance, substituting mechanical information display with optical detection and computational analysis.
2Productivity
If users drive around parking lots to find vacant parking spaces, then no additional navigation equipment is needed, but time is wasted and parking lot utilization is inefficient
Solution Approach 1:
The system performs preliminary detection and analysis of parking space availability before the user arrives. The server continuously monitors the parking lot through cameras, pre-identifies vacant parking spaces, and prepares navigation routes in advance. When a user enters, the system immediately provides guidance to an available space, eliminating the need for users to drive around searching.
Solution Approach 2:
The system establishes a feedback loop where camera images are continuously processed to update the server about current parking space status. This real-time feedback enables the system to dynamically adjust navigation guidance based on current conditions, ensuring users are directed to actually vacant spaces and improving overall parking lot turnover and utilization.
3Measurement precision
If multiple cameras are deployed to achieve accurate vehicle positioning and parking space detection, then positioning accuracy is improved, but system complexity and cost increase
Solution Approach 1:
The patent divides the parking lot monitoring into multiple camera zones, with each camera responsible for specific areas. The server processes images from multiple cameras separately and integrates the information to achieve comprehensive coverage and accurate positioning. This segmentation allows the system to achieve high precision through distributed detection rather than requiring a single complex system.

AI summary
A navigation method in the field of intelligent driving technologies includes obtaining images shot by a plurality of cameras; obtaining location information of a target vehicle based on the images shot by the plurality of cameras; after a target parking space for parking the target vehicle is determined, generating a navigation route based on the location information of the target vehicle and location information of the target parking space; and sending the navigation route to a terminal device such that a safety condition in the parking lot can be predicted to assist in safe driving of the target vehicle.
