This section defines all you need to know about ZEB-CAM, how to operate, collect data and download video.

HINT: Before starting to scan with ZEB-CAM, it is important to pre-plan your survey. If you haven't done so already, please have a look at Scanning with Colour in Mind section on the Survey Preparation page. If you are looking for how to process the video data, please wee HUB section.

Video above shows step-by-step operation for ZEB-CAM using standard system.

ZEB-CAM Contents

Once you have received your ZEB-CAM it will contain the following for the Standard system. For the Real-Time System the only difference will be the cable (no 2 in the image below) which, instead of having a blue connector in the logger will have an USB end which is plugged in the Real-Time Data Logger.

The ZEB-CAM will have pre-set parameters which work best with the REVO system. It is not recommended to change the camera settings unless you have prior knowledge in this area.

If for any reason these have changed, it is important to make sure that the settings are set back to the ones pre-defined below, in order to work properly with REVO system.

Video Settings:

Resolution - 1440;

Frames per second - 30;

Field of View - Wide;

Camera Setup:

Orientation - UP;

Default Mode - Video.

If the ZEB-CAM was purchased after the REVO system, the REVO System may need to be updated in order to be able to read an additional IMU information from the camera. This will mean that the firmware update in the datalogger is needed.

If an end user has an older version of the firmware the local distributor may need to manually change the old card inside the datalogger.

ZEB-CAM Installation

  • Remove the ZEB handle by unscrewing the orange knurled wheel at the top of the handle.
  • Fit the ZEB_CAM to the base of the REVO using the 3 x M4x8 caps screws supplied with the ZEB-CAM and tighten with the 3mm hex key. Do not overtighten or you risk stripping the threads in the base of the REVO, just nip the screws tight.
  • Refit the handle into the underside of the ZEB-CAM mount.

ZEB-CAM Operation

For a full step-by-step guide on ZEB-CAM operation, it is recommended to watch the video at the top of this page.

Important Note: Make sure that all cables are properly connected and that the datalogger can read the IMU data feed for the camera

The camera is connected correctly if:

- the light indicator has blinked red twice (applicable to the Standard system)

- a little camera symbol appears in the top left-hand corner of the main interface (applicable to the Real-Time system)

It is important to keep in mind, that the ZEB-CAM is independent from the system. This means that prior to the scan, one needs to make sure that the camera battery is charged, and the SD card has enough space for the video data.

After the scan, video data has to be downloaded by taking out the SD card.

ZEB-CAM Operation Check list

  1. Ensure the microSD card is inserted into the card slot behind the cover on the side of the camera
  2. Ensure there is adequate free space on the SD card.
  3. Ensure the camera battery is adequately charged.
  4. Connect the ZEB-REVO to the data logger, boot up the data logger and initiate the scan in the same way described in the ZEB-REVO User’s Manual.
  5. Immediately after starting the video recording, start the REVO rotation by pressing the button on the side of the REVO, pick up the scanner and start the scan.
  6. At the end of the scan, stop the REVO head rotation and immediately stop the video recording by [short] pressing the shutter/select button on top of the camera. The camera should beep several times and automatically power off to maximise battery life.

Downloading the data

The resulting video data is logged directly to an internal microSD card in the camera.

The scan data download is based on a connection to the datalogger (via the download cable and the USB) . But the information from ZEB CAM is stored internally within the camera.

Therefore, the microSD must be removed from the ZEB-CAM and inserted into your machine to download the data.

Making Use of the Video Data in HUB

The processing of video data together with REVO point clouds are fully described in the Software section, GeoSLAM HUB.

When video is processed together with all other REVO data, the point cloud can be viewed together with synchronised video in the HUB Viewer giving it more context. This is where the point cloud can be colourised and more.
