Abstract

An object detection method is executed by an object detection system for detecting data corresponding to a specific object in data received from sensors. The system includes a plurality of monitors, an application device, and a data accumulator. The method includes the followings. The application device specifies reference data corresponding to the specific object. Each of the plurality of monitors samples data received from a sensor to generate and transmit sampled data. The data accumulator analyzes sampled data received from each of the plurality of monitors in accordance with an analysis logic to generate first analyzed data. The data accumulator determines whether the first analyzed data matches the reference data specified by the application device. The data accumulator transmits a detection notification to the application device when analyzed data generated from sampled data received from a monitor out of the plurality of monitors has matched the reference data.
