Disclosed is a people counter including a setting interface and a setting method thereof. Since a reference width used to count of a moving object within an image is visibly arranged and displayed on a screen so that a detected width of the moving object can be compared with the reference width, setting and verification for count is very easy. In addition, since the interface can be freely moved for adjustment and comparison of a reference width using a pointing device such as a mouse, thereby providing verification and resetting which are intuitive and practical over conventional manual adjustment schemes, count accuracy can be easily increased in different environments depending on conditions or type of moving objects within an image.

The present invention provides an apparatus and method for camera parameter calibration which is capable of easily and simply setting physical and optical characteristic parameters of a camera in order to acquire information on actual measurement of an image provided through the camera with high accuracy. The camera parameter calibration apparatus and method has an advantage of correct image analysis that it is capable of increasing accuracy of information of measurement through an image only with an intuitive interface manipulation, without taking a time-consuming and incorrect actual measurement procedure, by determining parameters of the space model corresponding to the image by displaying a 3D space model corresponding to a real space of the image on the image and changing and adjusting visual point parameters such that the 3D space model matches the display image, and regarding the determined parameters of the space model as camera parameters of the image.
