3D Imaging for Planar Measurement

StereoCameraFor an upcoming application we’re going to be researching how the accuracy of planar measurements might be improved through the use of 3D imaging – particularly a camera pair. The concept is that point imaging in stereo may enhance general single-plane measurement accuracy in one or […]
