摘要： An intruding object detecting method and an intruding object monitoring apparatus for detecting a target object intruding into an image pickup region while reducing the error detection of moving objects other than the target object. A difference in pixel value between an input image signal and each of different image signals in a predetermined number of frames greater than one is calculated for each pixel to thereby obtain differential images in the predetermined number of frames. The differential images in the predetermined number of frames are synthesized in predetermined proportions to thereby generate a synthesized differential image. The synthesized differential image is binarized on the basis of a predetermined threshold value to thereby generate a binarized image. A binarized object in the binarized image is detected as an object intruding into a monitoring visual field.

摘要： An object tracking method and an object tracking apparatus. Based on two or more frames of images acquired at different time points from an imaging unit, an image changing area is detected between the frames. Based on the image changing area thus detected, the position of an object is detected. The detected position of the object is set as a new detected position of the object in place of the present detected position of the object, thereby detecting and tracking an object intruding into a monitor area.

摘要： An intruding object detecting method and an intruding object detecting apparatus for judging whether an detected object is an intruding object or not even in the condition that there are shadows of moving objects other than target objects to be detected, such as shaking trees, leaves thereof, etc. An image signal is supplied from an image pickup device; a moving object is extracted from the image signal by a subtraction method; division is made between the image signal and a reference background image signal for every pixel so as to produce a ratio image; a histogram of luminance values (pixel values) is calculated on a part of the ratio image corresponding to the moving object extracted in the extracting step; a pixel value on the part of the ratio image corresponding to the extracted moving object is calculated in ratio representation from the calculated histogram; the calculated pixel value in ratio representation is estimated; and the extracted moving object is judged to be an intruding object or not, on the basis of the estimation of the pixel value in ratio representation. Thus, intruding objects are detected in the field of view to be monitored.

摘要： An object is detected in comparison between an input image from an image pick-up device having a zoom mechanism and a template image stored in a manner that a first image within a view field of the image pick-up device is stored as a first as the template image, a power of the zoom mechanism to be changed is recorded, a second image to be detected is picked-up from the image pick-up device. Then, a size of either one of the template image and the second image is changed on the bases of the changed power of the zoom mechanism, and a template matching is performed between the template image and the second image to detect the object. This process makes it possible to track an object within the view field.

摘要： A monitoring method and apparatus for detecting an intruding object within a monitoring field of view by applying a subtraction method to an image obtained from an imaging device. A differential image of luminance values between an input image from the imaging device and a reference background image stored in a storage device is generated. The differential image is binarized using a predetermined binarization threshold value and the bianrization threshold value is changed until a noise level of a bianrized image becomes not greater than a predetermined value and based on a binarization threshold value at which the noise level becomes not greater than the predetermined value, an intruding object is detected.
