Point Cloud and Image Roaming
Steps
1.After creating a new project, a 3D window and an image window will be opened, and the point cloud data will be displayed in both the 3D window and the image window, and the image will only be displayed in the image window. The user can choose to show or hide the corresponding data through the check box in front of the data name in the project management window.
2.In the menu bar uncheck , the user can browse only the image data in the image
3.Click the color bar tool on the left side of the window to switch the display mode of the point cloud, including by elevation, intensity, category, RGB, number of echoes, time, mixed display, combined display, display by selected color and EDL display, EDL can be used in conjunction with other display methods to enhance and display the contour feature information of point cloud objects. The following picture shows the effect of point cloud displayed by elevation + EDL.
Note:
Display modes such as elevation, intensity, RGB, etc. on the toolbar work on all point clouds in the project. If you need to give a separate display effect to a point cloud, right-click on the data name and select View Mode > By Elevation/Intensity/Category etc.
The EDL display effect is related to the window. If you need to display the EDL effect in a window, click the mouse anywhere in the window to activate the window, and then click the EDL button.
4.Camera ID: Pull down to switch to display the corresponding camera image.
5.Click Select Frame button, and the user can select the image exposure position on the track in the 3D window or the image window, and jump to the selected image position.
6.Click Next Frame button jumps to the next frame of the current image. Click on Previous Frame button jumps to the previous frame of the current image.
7.Drag the slider to switch different image positions or directly input the number of image frames.The step size is how much to jump each time during automatic roaming or when going to the next/previous frame. The speed multiplier adjusts the roaming speed during automatic roaming, with a minimum of 1 and a maximum of 10.
8.Click Auto Roam button to roam the point cloud and image from the first-person perspective in the image window. Click this button again to stop the automatic roaming. If the viewing angle of the image window changes, you can click the space bar on the keyboard to restore the default forward direction.
Note:
1.There are two ways to control the display/hide of the laser point cloud: click the Show Point Cloud button on the menu bar; adjust the transparency scroll bar. By controlling the display/hide of the point cloud at the right time, the efficiency of point selection can be effectively improved.
2.In general, it is easier to select points by setting the point cloud display mode to display by intensity.
