Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems often provide inaccurate positioning of target vehicles, leading to reduced vehicle finding efficiency and poor travel experiences due to complicated topography and unfamiliarity with the area.
Innovation Solution
A position update method that uses GPS data combined with real images from a photographing device to correct the vehicle's position, utilizing a street-view database for comparison to achieve a more accurate second position, and subsequently generates a navigation route for easy vehicle location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is used to provide vehicle location information, then the positioning function is achieved, but the positioning accuracy is insufficient leading to wrong directions and difficulty in finding the target vehicle
Solution Approach 1:
The patent combines GPS positioning with image recognition technology to correct vehicle position information. The system merges satellite-based GPS data with visual verification from photographing devices to achieve more accurate positioning, directly addressing the insufficient GPS accuracy that causes wrong directions and extended vehicle finding time.
Solution Approach 2:
The patent replaces purely mechanical/GPS-based positioning with an optical recognition system. By using photographing devices to capture images and compare them with database images, the system substitutes the mechanical GPS positioning method with an optical verification method that can correct position errors and provide more accurate location information.
2Area of stationary object
If navigation systems provide approximate range of vehicle position, then coverage is improved, but positioning precision deteriorates making it difficult to locate the exact vehicle position
Solution Approach 1:
The patent segments the positioning process into two stages: first providing approximate position coverage through GPS to guide users to the general area, then using image recognition to segment and identify the exact vehicle position within that area. This segmentation allows the system to maintain broad coverage while achieving high precision at the final location.
Solution Approach 2:
The patent adds a visual dimension to the traditional GPS positioning system. By incorporating image data from photographing devices and comparing it with a database of location images, the system transitions from purely coordinate-based positioning to a multi-dimensional approach that includes visual verification, thereby achieving both broad coverage and high precision.
3Ease of operation
If traditional positioning systems are used in complicated topography, then basic navigation is provided, but positioning accuracy deteriorates causing long search time even when reaching the vicinity
Solution Approach 1:
The patent introduces image recognition as an intermediary between GPS positioning and vehicle location identification. In complicated topography where GPS signals may be weak or inaccurate, the photographing device captures images that serve as intermediaries to verify and correct the position information, enabling accurate vehicle location even in challenging environments with maintained ease of operation.

AI summary
A position update method and a apparatus, a position display method, a navigation route display method and a vehicle are provided. The position update method comprises: acquiring information of a target vehicle, wherein the information of the target vehicle comprises a first positioning position of the target vehicle detected by a GPS component of the target vehicle and a real image taken by a photographing device of the target vehicle; updating the first positioning position to a second positioning position according to the real image, wherein the second positioning position is configured to represent a current position of the target vehicle. The position of the target vehicle obtained by the position update method is more accurate, and the problem of low vehicle searching efficiency or difficulty searching caused by inaccurate position of the target vehicle in the prior art can be avoided.
