Wireless Following Target Identification in GPS-Denied Occlusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for vehicle platooning and following targets are limited by the need for license plates or GPS, making them unreliable in occluded or GPS-denied environments.
Innovation Solution
A following target identification system that uses a portable information generation terminal with wireless communication to provide following target information, including speed and angular velocity, allowing flexible target selection and accurate positioning through a combination of wireless communication, optical measurement, and inertial measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If license plate recognition is used for following target identification, then vehicle platooning can be implemented, but the system becomes unreliable when the license plate is occluded by other vehicles
Solution Approach 1:
The portable information generation terminal serves multiple functions: it generates following target information, provides wireless communication capabilities, and enables identification of various moving objects (vehicles, robots, people) beyond just license plate recognition. This multi-functional approach allows the system to adapt to different following targets and environments.
Solution Approach 2:
The portable information generation terminal acts as an intermediary between the following target and the moving object's identification system. Instead of directly recognizing license plates or visual features, the terminal provides structured following target information through wireless communication, enabling reliable identification even when visual recognition would fail due to occlusion.
2Adaptability or versatility
If GPS-based coordinate information is used for following target identification, then occlusion by other vehicles does not affect identification, but the system becomes unusable in GPS-denied environments
Solution Approach 1:
The portable information generation terminal provides following target information that works across multiple environments and scenarios. It enables the system to function whether GPS is available or not, whether the target is a vehicle, robot, or person, and whether visual recognition is possible or occluded.
Solution Approach 2:
The system replaces reliance on visual-mechanical recognition systems (license plate cameras) and satellite-based GPS systems with a wireless communication-based information transmission approach. The portable terminal transmits following target information directly to the moving object, eliminating dependence on line-of-sight visual recognition or satellite signals.
3Reliability
If visual recognition of license plates is used, then following target identification can be achieved, but the system cannot identify non-vehicle targets without license plates
Solution Approach 1:
The portable information generation terminal enables the system to identify and follow various types of moving objects including vehicles, robots, and people. The terminal generates following target information that is not limited to vehicle license plates, allowing the moving object to follow any target equipped with the terminal.
Solution Approach 2:
The system separates the identification function from the target's inherent features (like license plates). Instead of recognizing specific visual features of the target, the system receives structured following target information from the portable terminal, which can be attached to or carried by any type of moving object.

AI summary
A following target identification system is used for identifying a following target of a moving object configured to move autonomously. The following target identification system includes: a portable information generation terminal having a wireless communication function and configured to generate following target information about a movement of the following target in a state where the information generation terminal is carried by the following target; a communication unit included in the moving object and configured to receive the following target information sent from the information generation terminal via wireless communication with the information generation terminal; and a following control unit included in the moving object and configured to determine a position of the following target based on the following target information.
