This control also appears on the CameraTracker tab. • Match selection position, orientation, size - the scene is snapped to a new position, orientation, and size depending on the points selected. Stefan first steps through all the setting you need to know for the camera tracker node. • Unknown Constant - this is the default option. This should be a frame where there is a large number of tracks distributed over the image with a good variation in depth. This allows you to avoid problems with image quality, particularly in high contrast areas of the frame (where highly aliased, or jaggy, edges may appear if pixels are not filtered and retain their original values). Defines a cubic term that affects the radial distortion of the texture applied to the card, and the edges of the card. • Known - select this option if the focal length is available and enter a value in the Length control. Scale scene correctly when camera tracking. Live Streaming. You can adjust rotate values by holding down Ctrl/Cmd and dragging in the 3D Viewer. This can be useful if you have a difficult sequence to solve. Sets the lens type that CameraTracker should expect: Spherical or Anamorphic. • Undistortion - creates a LensDistortion node with Undistort enabled. This allows you to distort an image projected onto a card in 3D, for example, to simulate camera lens distortion effects, such as barrel distortion. Scales the scene simultaneously on the x, y, and z axes. Sets the center point offset for the camera projection. Quick Glance Step-by-Step. Click to recalculate the XYZ coordinates of the current selections in the tracks list. First, do the preparatory work before the camera tracking, all with roto not want to be moved to track the characters or objects covered with masks 2. Note:  This control is only available when Range is set to Reference Frames. • Max Error - reduce this threshold to reject tracks with a large reprojection error in isolated frames. 2019年11月5 日 2020年1月6日 gloriayujiefan Leave a comment . You can also adjust translate values by clicking and dragging the handles in the 3D Viewer. You can adjust the minimum using the Min Length control. Note:  Creating Cards from sequences can take long time, depending on the number of frames present. When enabled, cone shaped 3D markers are displayed on your points in the 3D Viewer. Sets the distribution of features in relation to each other. You can adjust this value to test whether a track is reliable. • track len - min - the minimum length of the tracks at each frame (in frames). Nuke's tracking tools help excel at making getting through your work quicker. Equivalent value for the c (r^1) control on LensDistortion tab of the Card node. That includes the ability to track shots both in 2D and 3D space. Sets the number of features to track in each frame - ideally you should use more than 100 tracks per frame. Camera Tracking.
