[0056] 1. Through the environmental modeling, priority allocation, and dynamic path optimization technologies of the inspection path algorithm module, dynamic adjustment of camera viewing angles and inspection paths is achieved. Traditional inspection systems rely on manual path planning, which may lead to blind spots in monitoring coverage.

[0057] 2. By introducing a software debugging and error-proofing mechanism, the system can detect camera installation errors and make real-time corrections. For example, during the 3D modeling phase, the deviation between the camera's theoretical installation angle and the actual measured angle is calculated, and dynamic adjustments are made based on the cumulative error coefficient to ensure that the monitoring range remains consistent with the calculated path.

[0058] 3. The inspection task execution supervision module can calculate the execution deviation value in real time and monitor the execution accuracy of the inspection task; based on the evaluation of path deviation factors, coverage area factors and task execution factors, the system can identify problems such as errors between the actual inspection path and the ideal path, insufficient monitoring coverage, and camera rotation accuracy deviation; once the system detects that the inspection task deviation value exceeds the preset threshold, it will trigger an alarm and adjust the inspection parameters, thereby improving the reliability and adaptability of the entire property management system.
