Compare scans

This function compares two different scans in the same area together. For this function to work, the VisionLidar project must contain at least two separate scans. Select the two scans to be compared in the “files to compare” section. The comparison is made perpendicularly to a selected plane or a surface. The “range of colors” is a histogram with ranges distributed equally within the set interval, which is the “Color interval” value. Any points that are outside of the range (further than the “Cutoff distance”) are cut out of the view and excluded from the histogram results. To calculate the histogram values, click on “Compare” and distribution values will appear in the right column.

Clicking on “Compare” will also display the results graphically in a secondary window. To view the colors in the secondary window, the view “Color by RGB” must be selected.

A .PDF report can be created with this tool. The report will contain a title, a subtitle, a histogram and a printscreen of the secondary window. To modify the title and subtitle, click on the “...” button next to the “Create Report” button. The titles may be personalized here. Clicking on “Create Report” generates a .PDF file showing the histogram and a screen capture of the secondary window when the function was triggered. It is recommended to hide unwanted classes and to create a fence around the analysed area to obtain the clearest possible report.
