Vehicle-Based Image Processing for Student Off-Route Detection

The patent introduces vehicles as intermediary devices to monitor student positions. Instead of requiring students to carry mobile terminals, the system uses vehicles (such as buses or cars) that students ride to capture images and obtain position information. The vehicle acts as a mediator between the student and the monitoring system, enabling safety monitoring even when the student does not have a mobile terminal.

The patent makes the monitoring system universal by allowing any vehicle with image capturing capability to participate in student safety monitoring, not just student-owned mobile terminals. The system can process images from various vehicle types (buses, cars, taxis) and integrates multiple data sources (image recognition, position information, alarm signals) to provide comprehensive monitoring coverage for all students regardless of whether they carry personal devices.

The patent leverages the existing image capturing units that are already installed in vehicles for their primary function (driver monitoring, security) and adds student safety monitoring as an additional function. This multi-functional approach expands monitoring coverage without requiring separate dedicated equipment, as the same camera system serves dual purposes.

The system uses position information and image capturing capabilities that are already present in the vehicle infrastructure. The vehicle's existing systems (communication units, position information obtainment units) are utilized to support student monitoring, reducing the need for additional complex equipment. The system serves itself by integrating monitoring functions into existing vehicle components.

The patent performs image capturing and preliminary processing actions in advance during vehicle operation. The image capturing unit continuously captures images, and the position information is continuously obtained, so when a student is detected or an alarm is triggered, the relevant information is already ready for immediate notification. This preliminary action reduces the need for high-energy real-time processing at the moment of detection.

The patent replaces continuous high-energy real-time processing with event-driven processing. Instead of constantly analyzing all captured images for student presence, the system processes images and position data only when specific events occur (student detection, alarm signal, off-route detection). This substitution of continuous mechanical processing with event-triggered processing significantly reduces energy consumption while maintaining rapid response capability.
