Solution Overview

Problem

Existing object sensing devices face challenges in improving pedestrian detection performance due to limited computation resources, as they must process multiple objects simultaneously without enhancing the sensing performance itself.

Innovation Solution

An object sensing device that includes an image capture unit, a processing device with a scene analysis unit, a process priority change unit, and an object-to-be-sensed sensing unit, which analyzes the travel scene, changes sensing process priority, and adjusts parameters to enhance pedestrian detection by prioritizing and optimizing the sensing process based on calculated pedestrian existence probability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If more detailed processes are executed in the processing device to improve sensing performance, then pedestrian detection accuracy is improved, but computation resources are exceeded

Engineering Contradiction:
Improvepedestrian detection accuracyVSAvoidcomputation resources
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent changes the parameter of process execution priority based on pedestrian existence probability. When pedestrian existence probability is high, the system executes detailed sensing processes with high priority to improve detection accuracy. When probability is low, it executes with low priority to conserve computation resources. This dynamic parameter adjustment resolves the contradiction between detection accuracy and resource consumption.

2Measurement precision

If the processing device intensively executes calculation processes for pedestrian sensing, then sensing performance is improved, but other object sensing processes are affected

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent implements dynamic priority adjustment for different sensing processes based on pedestrian existence probability. The system dynamically changes the execution priority of pedestrian sensing processes while maintaining adaptive priority for other object sensing processes. This dynamic scheduling ensures that pedestrian detection receives intensive computation when needed without completely blocking other sensing operations, thus maintaining overall system productivity.

3Measurement precision

If computation resources are allocated to enhance pedestrian detection, then detection capability is improved, but limited computation resources become insufficient for processing multiple objects

Engineering Contradiction:
Improvepedestrian detection capabilityVSAvoidcomputation resource allocation complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a pedestrian existence probability parameter that dynamically controls resource allocation. Based on this probability parameter, the system automatically adjusts the computation resource allocation for pedestrian detection versus other object sensing. This parameter-based control mechanism simplifies the complexity of resource management by providing a clear decision criterion: high probability triggers resource-intensive processing, while low probability conserves resources for other tasks.
