 If the the camera is held vertical, how can we exchange the coordinate of the camera?
As the camera is held breadthwise, the coordinate X=x0£¬Y=y0. If the the camera is held vertical, we have to adjust the x0£¬y0 directions when you set up the new project.
Clockwise circumvolve: X=y0 Y=-x0
Counter-clockwise circumvolve: X=-y0 Y=x0
Why can we not get the free-network and the adjustment with the proper overlap degree of the images and the camera baseline?
Check the order of the station and the images if it is all placed from the left side to the right side. We suggest to keep the order from the the left side to the right side when you take pictures. If not, pls revise the image names when you separate the stripes.
What is the Non-Contact Measurement?
Non-Contact Measurement is to place the control board by the feature point. It include two ways, one is using the non-prism total station to get the 3D coordinate. The other way is through the forward intersection£šusually three stations£©£¬ calculate the 3D coordinate from level angle, azimuth angel and vertex distance of each station. When you choose the second method, pls pay more attention of the feature point choosing; do not use the jut of the rock to avoid the precision problem. The best point is on the two difference color of one rock. No matter the Non-Contact Measurement or the forward intersection ways, the point you choose for measuring should have obvious feature and make sure you can observe the point from each station.
Why can we not get the adjustment with the even control point , well precious and free- network succeed ?
As the photogrammetry is the left-hand-coordinate and our soft is the right, we have to change the coordinate X and Y in the control point file *.CTL and then adjustment
