Now  based on binocular parallax of human eyes  we advance a method used to get the distance by measuring the offset on image panel. On this foundation  we also analyze the error in forward. The academic analysis indicate that the measurement would be impacted severely by transverse offset and angle-measuring offset  in contrast  much slightly by lengthways offset. When we put this facility into practice  this facility can suffice practical demand completely if we select the space between bi-camera and the focus of facility rationally.
