Lidar USB Viewer#

This tool displays a graphical view to render data provided by a YDLidar G2 connected to USB port.

After installation (see Install), the Lidar USB Viewer is launched with:

$ cogip-lidarusb

The serial port is detected automatically by the YDLidar SDK, so this tool has no specific options.

Interface#

The graphical interface provides a polar chart and table view.

View with unfiltered data

View with filtered data

Polar Chart#

Two kind of values are drawn on the chart:

  • distance values for each degree (in millimeters)

  • intensity values for each degree

Below the chart, the Max Distance and Max Intensity sliders allow to zoom on the distance and intensity axes.

The Distance filter slider can be enabled/disabled using the checkbox. If disabled, distance values displayed on the charts are raw data. If enables, a filter is applied to drop corrupted values and limit the detection to the maximum distance selected by the slider.

Table#

The table on the right of the window presents the same data as the chart but in numeric format.
