| Abstract: | A geometric demarcating method based on combination of a dummy ruler and a real ruler of the emission spectrum torncgraphy system is proposed. The demarcating parameters of the system are calculated with the trim size of the object and the pixel number of the image of the object without regard to the parameters of the camera. The experiment indicates that this method is simple and effective for the emission spectrum tomography system. |
