1. A method of building a stereoscopic model with Kalman filtering (KF), the method comprising the steps of: (a) providing a body, a processing device, and a computing device, with the body having a sensing device, the processing device having a storing unit and being in signal communication with the sensing device and the computing device, respectively; (b) capturing an image from a space with the sensing device; (c) classifying the image into a static image and a dynamic image with the processing device, with the static image carrying a first time static image information, a second time static image information, and a third time static image information, with the dynamic image carrying a first time dynamic image information, a second time dynamic image information, and a third time dynamic image information; (d) calculating a static object spatial position and a corrected static object spatial position of the static image by the computing device with Kalman filtering according to the first time static image information, the second time static image information, and the third time static image information; (e) storing data indicative of the static object spatial position and data indicative of the corrected static object spatial position in a first database by the storing unit; (f) building a first stereoscopic model by the processing device according to the first database; (g) calculating a dynamic object spatial position and a corrected dynamic object spatial position of the dynamic image by the computing device with Kalman filtering according to the first time dynamic image information, the second time dynamic image information, and the third time dynamic image information; (h) storing data indicative of the dynamic object spatial position and data indicative of the corrected dynamic object spatial position in a second database by the storing unit; and (i) building a second stereoscopic model by the processing device according to the second database.
