This paper proposes a measurement method of double cameras solid vision based on dot structure light system. Firstly, the basic principle is described in detail, the simple physical explain is given, the relation between the coordinates of imaging dot of double cameras and that of testing dots are deduced, the transform matrix of measurement system constituted by double cameras is obtained, the method of deciding energy center of each testing dot on the calibration board is proposed. Secondly, corresponding error estimation method is proposed. Finally, the results of measurement experiment are given which show that its value of measurement error is very small.
