- * Setup the source of the camera. For this example, download this [sample data set](https://raw.githubusercontent.com/introlab/rtabmap/master/bin/data/samples.zip) and extract it anywhere. Open menu Detection -> "Select Source" -> "More options..." (or Preferences->Source panel), then select "Source" -> "RGB". Scroll down to RGB section and select "Images" instead of "Usb camera", then select the directory containing images just extracted. Make sure the input source is not 0 Hz (otherwise the images will be processed very fast).
