Pedestrian Path Tracking Without Pre-Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring systems using cameras and infrared sensors cannot display the actual path of pedestrians on a map, limiting their effectiveness in pedestrian traffic analysis, especially in environments with a high volume of unknown individuals.
Innovation Solution
An information processing apparatus that displays captured images and path information by overlapping map data with time and camera-specific information, allowing for inter-camera person identification and tracking without pre-registration, enabling the visualization of pedestrian paths and corresponding images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If face authentication and pre-registration are used to identify persons, then person identification accuracy is improved, but the system cannot handle places with indefinite numbers of people coming and going
Solution Approach 1:
The system performs preliminary detection of persons and generation of traveling paths without requiring pre-registration or face authentication. By detecting persons and creating their movement paths in advance, the system enables subsequent analysis and identification without needing prior database entries, thus resolving the contradiction between identification accuracy and adaptability to indefinite crowds
Solution Approach 2:
Instead of requiring original face authentication, the system creates a copy of the traveling path as a unique identifier for each person. This path copy serves as the basis for person identification and tracking, eliminating the need for pre-registration while maintaining the ability to distinguish between different individuals in crowded environments
2Device complexity
If independent monitoring systems are used, then system simplicity is maintained, but the image of actual persons corresponding to traveling paths cannot be displayed
Solution Approach 1:
The patent merges the traveling path information system with the image monitoring system by superimposing path data on camera images. This integration allows the display of actual person images corresponding to detected traveling paths, combining the simplicity of independent systems with the enhanced capability of correlated visual information without requiring completely new system architecture
3Productivity
If traveling paths are displayed on maps, then pedestrian traffic analysis is improved, but the connection to actual captured images is lost
Solution Approach 1:
The system uses the traveling path as an intermediary element that connects map-based spatial information with actual captured images. By establishing this intermediate linkage, the system enables efficient pedestrian traffic analysis through map visualization while simultaneously maintaining the connection to original images for detailed verification, thus resolving the contradiction between analysis efficiency and information completeness

AI summary
An information processing apparatus that causes a display to display an image captured by one or more image capturing apparatuses is provided. The information processing apparatus obtains one or more pieces of path information indicating a change in a position of an object captured by the one or more image capturing apparatuses, and causes the display to display map information overlapped with the one or more pieces of path information and at least one of information related to a time corresponding to the path information and information that can specify an image capturing apparatus corresponding to the path information.
