Export Orthophoto

1.Click on the Orthophoto button to open the Orthophoto Export Settings window. As shown below, you can export the elevation, intensity, density, and RGB images of the point cloud in conjunction with the Horizontal Section Tool and Vertical Section Tool. The exported image supports tif and png formats, and the results can be opened and measured in other GIS software.

Horizontal Section Tool

1.Check the Horizontal Section to set the minimum and maximum values of the horizontal section through a dual slider. The 3D window will display the results in real time. You can reset the current settings by clicking on the Reset button. Check the 2D mode to switch between 2D and 3D modes in the 3D window. Checking Reference Plane can turn on or off the reference plane in the current 3D window. It looks like this:

Horizontal Section

Vertical Section Tool

1.Check Vertical Plane and click on the button. The 3D scene will automatically switch to the top view.

2.Use the mouse to interactively draw a rectangle. The first two points determine the axis direction, and the third point determines the buffer size. Double-click to the end and slice the section, as shown below.

3.The 3D scene automatically switches to the front view, as shown below.

4.To fix the section buffer, you can click on the Buffer radio button and adjust the buffer value.

Export by Elevation

1.Check Elevation in the Orthophoto Export Settings Window-Mode. The point cloud in the 3D window will be displayed according to the elevation. The Point Cloud Color Mode Setting window on the right side of the software will pop up. You can select the current display color bar and other settings through the Point Cloud Color Mode Setting window, as shown below:

Display by Elevation

2.After setting the point cloud display, you can choose whether the exported image is colorized. If not checked, a binary image will be output. As shown below:

Export Binary Image by Elevation

3.If Colorized is checked, a color image will be output. As shown below:

Export Color Image by Elevation

Export by Intensity

1.Check Intensity in the Orthophoto Export Settings Window-Mode. The point cloud in the 3D window will be displayed according to the intensity. The Point Cloud Color Mode Setting window on the right side of the software will pop up. You can select the current display color bar and other settings through the Point Cloud Color Mode Setting window, as shown below:

Display by Intensity

2.After setting the point cloud display, you can choose whether the exported image is colorized. If not checked, a binary image will be output. As shown below:

Export Binary Image by Intensity

3.If Colorized is checked, a color image will be output. As shown below:

Export Color Image by Intensity

Export by Point Cloud Density

1.Check Density in the Orthophoto Export Settings Window-Mode. Since there is no option to display according to density in the point cloud display mode, there will be no change in the 3D window. At the same time, the color bar for exporting images according to point cloud density will be set in the Orthophoto Export Settings Window. If Colorized is not checked, a binary image will be output. As shown below:

Export Binary Image by Density

2.If Colorized is checked, a colorized image will be output. As shown below:

Export Color Image by Density

Export by Point Cloud RGB

1.Check RGB in the Orthophoto Export Settings Window-Mode. If the point cloud contains RGB information, the point cloud in the 3D window will be displayed according to RGB. If the point cloud does not have RGB information, the software output window will give a warning. After checking RGB, the colorization setting will be invalid, and only the color image containing point cloud RGB information can be exported. As shown below:

Export Color Image by RGB

Note: In each mode of export, there are options to check the maximum value, minimum value, and average value. This setting is effective for the mode settings exported according to point cloud elevation and intensity.

• Maximum value: When calculating the pixel value of each pixel in the image, it is calculated according to the maximum value of all point cloud elevations or intensities mapped to the current pixel.
• Minimum value: When calculating the pixel value of each pixel in the image, it is calculated according to the minimum value of all point cloud elevations or intensities mapped to the current pixel.
• Average value: When calculating the pixel value of each pixel in the image, it is calculated according to the average value of all point cloud elevations or intensities mapped to the current pixel.

Resolution Settings

There are currently three options for setting the resolution of the exported image:

• Current Window Resolution: The aspect ratio and resolution of the output image will be exactly the same as the 3D window. And it does not support setting.

• User-defined Resolution: The aspect ratio of the output image will remain the same as the 3D window, and the resolution of the image supports user setting through the world coordinate accuracy mapped by each pixel.

• According to Point Cloud: The aspect ratio of the output will be calculated through the bounding box of all current point clouds. The aspect ratio of the image is consistent with the calculated bounding box, and the resolution of the image supports user settings through the world coordinate accuracy mapped by each pixel.
