Description

Integrated Monitoring System Using Image Sensor and Radar Sensor The present invention relates to an integrated monitoring system of an image sensor and a radio wave sensor that enhances object recognition, identification, and tracking functions. Korea is renowned globally for its high penetration rate of video surveillance devices, including CCTVs. This should be interpreted not as a sign of a high crime rate, but as an indication of the country's strong pursuit of safety. Furthermore, various types of video surveillance devices are used in our country's military border surveillance systems, and aside from the armistice line, there are practically no borders with other countries; even at the armistice line, our country must maintain an active state of alert. However, the limitations of most video recording devices are clearly evident due to various causes. Effectiveness is significantly reduced due to image quality degradation caused by factors such as blind spots, camera performance, weather conditions, or the weather or terrain of the area near the monitored target. Furthermore, these issues prevent AI analysis capabilities from reaching a satisfactory level, ultimately requiring the investment of significant human resources. However, while an increase in human resources is required to monitor a large number of video surveillance devices, such resource allocation is impossible given the reality of Korea's declining population. Therefore, there is a need to develop an advanced integrated monitoring system based on image acquisition with a new concept that can improve visibility and dramatically enhance object detection and tracking capabilities for current video surveillance devices.
