Object Tracking Device Prohibition Region Stable Radar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution radar systems face challenges in stable target tracking due to the generation of multiple targets from the same object, leading to competition for observed values and loss of tracking reliability when the number of observations decreases, resulting in delayed vehicle control.
Innovation Solution
An object tracking device with a detection unit, prediction unit, first region setting unit, selection unit, estimation unit, registration unit, prohibition region setting unit, and registration prohibition unit, which calculates predicted values, sets a first region for observed value correlation, and a prohibition region to prevent multiple targets from the same object from being generated, ensuring stable tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple targets are generated from the same object to improve detection coverage, then the probability of detecting the object increases, but the stability of target tracking deteriorates due to competition for observed values
Solution Approach 1:
The patent merges multiple targets that originate from the same object by introducing a parent-child relationship structure. When multiple targets are detected from the same object, they are combined into a single parent target with multiple child targets, eliminating the competition for observed values while maintaining comprehensive detection coverage.
Solution Approach 2:
The patent introduces an intermediary mechanism (the parent target) that mediates between multiple child targets and the observed values. The parent target acts as a central coordinator that manages the allocation of observed values to child targets, preventing direct competition and ensuring stable tracking.
2Reliability
If the number of observed values decreases, then the processing load is reduced, but the tracking reliability deteriorates due to target loss
Solution Approach 1:
The patent performs preliminary actions by establishing parent-child relationships between targets before observed values become scarce. This pre-organization of target relationships ensures that when observed values decrease, the tracking system can maintain reliability through the established hierarchical structure rather than losing track of targets.
Solution Approach 2:
The patent segments the target tracking system into hierarchical levels (parent targets and child targets), allowing the system to handle observed value scarcity more effectively. This segmentation enables the tracking system to maintain multiple potential targets under a single parent, ensuring continuous tracking even when observations are limited.
3Productivity
If multiple targets compete for the same observed values, then detection flexibility is improved, but the processing time increases causing delays in vehicle control
Solution Approach 1:
The patent merges the management of multiple competing targets into a single parent target structure, simplifying the overall target management process. Instead of independently managing multiple competing targets, the system manages one parent target with organized child targets, reducing processing complexity and improving vehicle control response time.
Solution Approach 2:
The patent changes the organizational parameter of target management from a flat, competitive structure to a hierarchical parent-child structure. This parameter change fundamentally alters how targets are managed, reducing the complexity of observed value allocation and improving processing efficiency for vehicle control applications.

AI summary
An object tracking device according to one aspect of the present disclosure includes a detection unit, a prediction unit, a first region setting unit, an estimation unit, a registration unit, a prohibition region setting unit, and a registration prohibition unit. The registration prohibition unit prohibits observed values of at least one observed value detected by the detection unit and that are within a prohibition region set by the prohibition region setting unit from being registered as new targets by the registration unit.
