Abstract
There is provided an image analysis system having an image analysis server which analyzes an input image of a monitoring area and detects a state of a specific monitored object. The image analysis server is configured to divide, in the input image of the monitoring area, a portion of an area in which the monitored object is expected to be present into a plurality of grids, generate a trained model trained by associating '1' with an image of a grid in which the monitored object is present and “0” with an image of a grid in which the monitored object is not present for each grid, calculate, for the input image, a confidence of a presence of the monitored object for each grid using the trained model, determine a presence or absence of the monitored object in the monitoring area based on confidences of the plurality of grids, and detect an abnormality when a confidence value in at least one of the grids is inconsistent with the determination result.
