A method includes generating a disparity map according to two sets of image data, identifying at least one object in the disparity map, mapping the at least one object onto a plane view, tracking at least one object on the plane view, and providing a robust algorithm about a cross-line time interval and a cross-line degree. The robust algorithm includes detecting whether the at least one object enters a predetermined region when the at least one object crosses a predetermined boundary.

Method of operating three-dimensional video surveillance system

A method for intensifying identification of three-dimensional objects identification includes utilizing a left eye camera and a right eye camera to capture a left eye image and a right eye image, calibrating the left eye image and the right eye image to generate a calibrated left eye image and a calibrated right eye image, using the calibrated left eye image and the calibrated right eye image to generate a disparity map, differentiating a three-dimensional object from a background image according to the disparity map, projecting the three-dimensional object onto a plan view, filtering noise out of the plan view to generate a filtered three-dimensional object, determining whether the filtered three-dimensional object contains at least two three-dimensional objects, and separating the at least two three-dimensional objects if the filtered three-dimensional object contains at least two three-dimensional objects.

Method for intensifying identification of three-dimensional objects

Comparison of parameters, including width, length, depth, color, and shape of a target object with a reference object is performed through use of a stereo camera. If the parameters of the target object are within threshold values of the parameters of the reference object, a match is indicated. If not, a new reference object is selected for comparison with the target object.

Method of comparing similarity of 3D visual objects

A method to calculate a transform coordinate on a second video of an object having an target coordinate on a first video and related operation process and video surveillance system are disclosed. The method includes the steps of generating the first video with a first video surveillance device, generating the second video with a second video surveillance device, selecting a first predetermined number of first reference objects also existing on the second video from the first video, calculating a plurality of coordinate transform coefficients of a first coordinate transform function according to the first predetermined number of first coordinates where the first reference objects are on the first video and the first predetermined number of second coordinates where the first reference objects are on the second video, and substituting the target coordinate into the first coordinate transform function, which had the first coordinate transform coefficients, and calculating the transform coordinate.
