Extracts and the match based on two-dimensional picture characteristic point is the 3D reconstruction technology core. Taking binocular stereoscopic vision theory as a foundation  through extracts the characteristics of SURF based on the multi-scale analysis  this feature has specific scale reproducibility  put the epipolar constraints and disparity constraints as conditions judgement to specific screening  it is greatly reduced the search range. The experiment use the matching method for three different actual scenes  the results shows that the method can enhance the image matching speed and precision  and can get more precise dense parallax  used for reconstruction complete scene. 2012 IEEE.   Bi-camera ranger-finder and error analyze based on binocular parallax (EI CONFERENCE) 会议论文 2011 International Conference on Vibration, Structural Engineering and Measurement, ICVSEM2011, October 21, 2011 - October 23, 2011, Shanghai, China Wang Z.

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.

Finally  the width of slit and pitch and viewing distance and etc of parallax barriers are confirmed according to parameters of strips of lenticular sheets.Data analysis indicate that the brightness of our four-view image is increased three times because of using lenticular sheets instead of parallax barriers comparing with the autostereoscopic 3D projector using two parallax barriers plates.Parameters design of parallax barriers and lenticular sheets are finished  the feasibility and advantages of the 3D display of projecting are confirmed theoretically. 2011 IEEE.
