Efficient parallel processing for depth calculation using stereo

Simultaneous perimeter measurement for 3D object with a binocular stereo vision measurement system

“…Therefore, the prerequisite for the parallel optical axes is satisfied easily and precisely in our system by moving the gallery, without the requirement of the repeated adjustments as described in Ref. [6]. Second, the moving distance B in Fig.…”

“…This binocular vision model is complicated in terms of the stereo matching. In this paper, a different and simple binocular vision model proposed by Majumdar [6] is used. The two optical axes are parallel in this simple model.…”

“…The parameters of the two cameras are identical, while the two origins of two cameras are different. In this model, Y L ¼ Y R ; and the left camera coordinate system superposes the object coordinate system, so that the 3D coordinate of the detected spatial point W(X, Y, Z) is computed as follows [6]:…”

“…[6], which is omitted here. In this binocular vision system, the camera calibration is performed to meet the parallel requirement of the two optical axes.…”

Eye Gaze Based 3D Triangulation for Robotic Bionic Eyes

“…Usually, 3D triangulation can be performed using disparity and stereo extrinsic parameters [ 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. The stereo extrinsic parameters are calibrated offline [ 32 , 33 ] or online [ 34 , 35 , 36 , 37 , 38 , 39 ].…”
