摘要： For automatically detecting a moving object in an input image taken using a monitor camera or the like, an apparatus includes an input image extracting section, an input image retaining section, a background image retaining section, a background difference calculating section, a moving direction recognizing section, and a united judging section. A movement of an object is detected with precision even in an environment where illumination varies, irrespective of the relative position of a ridge line of the object and a border of unit blocks. And only the moving object can be detected stably even when the camera encounters swing, vibration, etc.

摘要： A moving body recognition apparatus which recognizes a shape and movement of an object moving in relation to an image input unit by extracting feature points, e.g. a peak of the object and a boundary of color, each in said images captured at a plurality of instants in time for observation by the image input unit. The moving body recognition apparatus comprises an image input unit for capturing images of an object as a moving body having a rotation, a feature point extraction unit for extracting feature points from the images inputted by the image input unit, a feature point storage unit for storing known position data of the extracted feature points, and a shape/movement recognition unit for calculating the actual positions and movements of the feature points of the object in the images by using the known position data of the extracted feature points outputted from the feature point storage unit.
