INTRODUCTION

1.

The ZEB-CAM is a colour camera accessor for GeoSLAM’s ZEB-REVO portable laser

scanner. ZEB-CAM incorporates a GoPro Hero Session action video camera. The image

data collected b the camera can be viewed alongside the 3D point cloud created b the

ZEB-REVO and used to extract contextual information.

1.2 PRINCIP AL OF OPERATION

The operation of the camera on ZEB-CAM is independent from operation of the ZEB-

REVO. The camera must be started and stopped manuall at the start and end of each

scan. The resulting video data is logged directl to an internal microSD card in the

camera.

The video data from ZEB-CAM and laser data from ZEB-REVO are combined in the

GeoSLAM Desktop processing application. A unique optical flow algorithm is used to

determine the relative timing between the video and laser data.

The viewer in GeoSLAM Desktop can be used to view the video data alongside the point

cloud data from the ZEB-REVO.

This chapter describes how to mount ZEB-CAM to the ZEB-REVO and how to operate ZEB-

CAM during REVO data capture.

3.1 MOUNTI NG ZEB-CAM

If the ZEB-CAM is not alread mounted on the ZEB-REVO, mount the camera b following

these steps:

1Remove the ZEB handle b unscrewing the orange knurled wheel at the

top of the handle.

2Fit 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 ke . Do not

overtighten or ou risk stripping the threads in the base of the REVO, just

nip the screws tight.

3Refit the handle into the underside of the ZEB-CAM mount.

4Connect the Micro-USB end of the ZEB-CAM cable into the socket on the

side of ZEB-CAM mount.

5Connect the other end of the ZEB-CAM cable to the AUX (blue) socket on

the ZEB-DL2600 data logger.

3.2 ZEB-CA M SETTIN GS

The GoPro Hero Session camera is delivered with configuration settings required for use

in ZEB-CAM pre-set. If for an reason the camera settings are changed the settings listed

in Table 3-1 must be reset to the values shown in order for the ZEB-CAM data to process

correctl .

3.3 CAPTURI NG D ATA WITH ZE B -CAM

Ensure the microSD card is inserted into the card slot behind the cover on the side of the

camera (see 5.2 Inserting and removing the memor card).

Ensure there is adequate free space on the SD card.

Ensure the camera batter is adequatel charged (see 5.1 Charging the batter ).

Connect the ZEB-REVO to the data logger, boot up the data logger and initiate the scan in

the same wa described in the ZEB-REVO User’s Manual.

After the s stem has initialised and the REVO LED has changed to green and before

activating the rotation of the REVO head, [short} press the shutter/select button on the

top of the camera. After approximatel 2 seconds the camera emits three beeps, and

automaticall begins recording video. The camera status led flashes red while the camera

is recording.

Warning – do not hold down the shutter/select button [long press]. This will switch the

camera from video to time lapse mode.

Immediatel after starting the video recording, start the REVO rotation b pressing the

button on the side of the REVO, pick up the scanner and start the scan.

Perform the scan following the guidelines set out in the ZEB-REVO User’s Manual.

At the end of the scan, stop the REVO head rotation and immediatel stop the video

recording b [short] pressing the shutter/select button on top of the camera. The camera

beeps several times and automaticall powers off to maximize batter life.

DATA PROCESSING

4.

The ZEB-CAM records video data to internal microSD card in MP4 format. Remove the

microSD card from the camera and cop the MP4 file(s)* to the processing computer

using the microSD to SD or microSD to USB adapter.

Select the corresponding video MP file(s)* when requested to do so b the GeoSLAM

Desktop application.

*ZEB-CAM video files are limited in files size to 4GB due to a limitation of the FAT32 disk

format. Videos in excess of 4GB (approximatel 9 minutes) are split into multiple MP4

files or chapters, each with a common file name plus index number to differentiate each

chapter. All chapters must be selected at the start of processing in order for the data to

process correctl .

5.1 CHARG ING THE BATTERY

The integrated batter comes partiall charged. No damage occurs to the camera or

batter if used before being full charged. To Charge the Batter :

1Open the side door.

2Connect the supplied USB cable to the Micro-USB port.

3Connect the other end to a 5V 1A USB power source, e.g. a standard USB

port on a computer.

The camera status led turns red during charging and turns off when charging is complete.

When charging the camera with a computer, be sure that the computer is connected to a

power source. If the camera status lights do not turn on to indicate charging, use a

different USB port.

5.2 INSERTIN G AND REMOVING THE MEMORY CARD

To insert the memor card:

1Ensure the camera is powered off.

2Open the side door.

3Insert the microSD memor card into the card slot at a downward angle

with the label facing down.

4Press the card in until it latches in place

To remove the memor card

1Ensure the camera is powered off.

2Open the side door.

3Gentl press the memor card in to unlatch it.

4Carefull extract the memor card

5.3 WIRELESS SETTINGS

The GoPro can be used remotel using the free GoPro App for Mobile via a WiFi

connection. We do not recommend using in this mode since it significantl reduces the

batter charge life.

The camera WiFi settings have been pre-set to the last eight digits of the camera serial

number. The serial number can be found on the inside of the side door:

SSID NNNNNNNN

Password NNNNNNNN

Where NNNNNNNN is the last eight digits of the camera serial number.
