摘要:
An intruder monitoring apparatus has at least a feature of correcting characteristic quantities by which an object to be monitored is specified, on the basis reference characteristic, when any change occurs in conditions of the video devices and environments. A further feature is provided which a plurality of scenes are monitored periodically by one camera and an image analysis function is driven so as to monitor any intruder only when the camera unit is fixedly directed to a specific scene among the scenes.
摘要:
The present invention has an object to measure the height of a liquid surface automatically by an image processing. According to the present invention, therefore, the situation over a side wall and the situation of the liquid surface in the image, as taken from an ITV camera, of the neighborhood of the liquid surface are image-analyzed to estimate the boundary position between the side wall and the liquid surface thereby to determine the position of the liquid surface on the image, and the liquid-surface position on the image is transformed from an image coordinate system to a real spatial coordinate system to determine a real position of the liquid surface.
