One analytical method of three-dimensional measurement with monocular vision, where the size of the object is known, was reveald. There is a possibility that the number of solution sets amounts to four. Thus, the process which discriminates the efficient set with a computer was given. Further, in order to apply this theory to measuring the three-dimensional displacement of the vehicle, the procedure, which transforms the vehicle coordinate system to the absolute coordinate system, was also shown. In addition, the three-dimensional measuring system of the vehicle displacement, where the 35 mm camera was placed in the vehicle, was organized, and some running experiments were made. Since we execute the measurement with one camera and obtain the solutions analytically, the process of the computation is simple and requires a short time.
