Abstract：The offects of the different structures on the binocular sensor accuracy under various ca-ses are analyzed comprehensively.An epipolar-slope matching method is proposed based on the epi-polar constraint.With this method，a fast matching speed is achieved and the measuring accuracy of sensor is improved.Experiment result shows that the measuring accuracy of sensor is better than±0.05mm.

Keywords：binocular sensor accuracy analysis epipolar-slope matching
