Mouse Pointers and Icons

Icon Description
Select a pixel Mouse pointer used to select pixels in images that represent an object to compute a 3D coordinate for.
Selected pixel Icon used to indicate the currently selected pixel on an image.
Solution location Icon used to indicate the location of the solution based on the currently selected pixels on the images.
Notes
  • Images must have known interior and exterior orientations and camera calibration.
  • Typically stereo images are captured using an imaging total station.
  • The Image Intersection view is used in conjunction with the Create by Image Intersection tool.
  • The View panel Fit, Pan, Window Zoom In and Zoom Out tools operate the same as they do in the model view.
  • After selecting the first pixel, magenta epipolar lines are displayed in the other images to assist with locating corresponding pixels in those images.
  • It is possible to select pixels from more than two images. All pixel selections that are not reset are included in the solution.
  • The values and precisions of the pending solution based on the selected pixels are displayed in the Create tool.
