+ Texturing improvements and better management of triangles without valid reprojection. + Added edge filter in the photoconsistency computation. + Texture computation is now divided in chunks to minimize memory usage + Photoconsistency computation is now split in chunk to minimize memory usage + Added splines to drawing elements (only 3DF Zephyr) + Merge workspace improvements (can now specify which elements to merge) + Significant SfM improvements both for accuracy and speed the action you described, to pick the distance in 3D, is by nature not accurate and won't allow you to measure the accuracy of the rescaling operation (as you will do it only on two points, and thus, you won't be able to compare it to other control distances and calculate the residuals) and is generally used where accuracy is not a big problem (e.g.+ Introducing 3DF Scarlet! A new dedicated standalone software explicitly designed for laser scan data registration (bundled with 3DF Zephyr) by using a total station) then you can also use that information to drive the reconstruction in the SfM stage, which will act and potentially change/aid the camera calibration If you have the 3D coordinate of your control points (e.g. Note that scaling using control distances is a rigid scaling, so you will not change any camera position at all. Tutorial on control points and distances is available here : This is the preferred way and the most accurate way using control distances, available in zephyr Pro and Aerial only. Then, add them as control distances, and use the scale world using control distances function. the height of a door) and pick those points in 2D from the images to create the control points in zephyr. the first one is to place control points in your scene (which can be with markers you measured, or any other known distance in the scene, e.g. What you described is rescaling via control distances.
