6 Capture Operation Instructions 6.1 Remote Controller Unit 6.1.
System setup interface Laser setup interface 6.1.2 Initialization Interface Description Long press Power On/Off key until heard a sound and the screen will automatically becoming bright and stay in the initialization interface. The progress bar is in the moving state, and the system is in the self-test state.
6.1.3 Main Display Interface Below figures show the main display interface of AlphaUni 900 and AlphaUni1300 controller which contains System state, GNSS state, IMU state, SD card state, Camera state, Laser state and related buttons. AlphaUni 900 Interface AlphaUni1300 Interface 6.1.3.1 System state System state shows connection state, timing information, and current battery power. When system timing fails, the UNLOCK will be displayed.
6.1.3.3 IMU state When the system timing successfully, the initialization of all system parts is normal. After user clicks "Create Prj", the IMU state starts to display the correct count and error count number of IMU. If the initialization of IMU is normal, it will show green. Otherwise, it will display red. In the process of operation, user need to pay attention to the correct count and error count.
6.1.3.6 Laser state ▪ Laser icon: It indicates the laser scanner status and generally it will show green, If the laser scanner does not work normally, it will display red color and please contact CHCNAV Support Team. ▪ Laser state: After successfully connect to LiDAR, the "link" state will be displayed. When the collection operation begins, the laser status will be shown as “capturing”. When the laser fails and disconnects during collection, the laser state will show “not link”.
6.1.4 System Setup Interface As shown in below figure, the system setup interface consists of trigger settings, laser settings and other settings. 6.1.4.1 Trigger settings ▪ Trigger mode: There are three types if trigger mode: time trigger, distance trigger and manual trigger. The default is manual trigger.
6.1.4.2 Laser settings Before start project, user need to set the scan speed and laser PRR first, then the Step Angle will be calculated automatically. The starting angle and the ending angle are 0 and 360 by default. It is important to note that the starting angle need to lower than the ending angle. 6.1.4.3 Other settings (Generally no use) ▪ Usr cmd: Support input relative code to check system when has issues.
6.1.6 Capture Process 1. After the system is initialized successfully, click “setting” to config relative parameters as required. 2. After settings are saved, click “Create Prj” to start POS collection. 3. When the time is starting, keep the equipment as stationary for more than 5 minutes to ensure the IMU is initialized successfully. 4. After 5 minutes static alignment, click “Capturing” to start laser data collection. 5.
The project is named by creation date for example 20170509. In the folder, the collected four files will be stored here: xxxxxx_D.DMR: Recorded DMR data (if have). xxxxxx_I.IMR: Recorded IMU data. xxxxxx_S.TXT: Recorded the data sent by control board. xxxxxx_T.TXT: Recorded GPS differential ephemeris data. 6.2.1.2 Export laser data Connect the data copy line between DATA interface and PC, and the other end of the network cable to computer network port. Power on the equipment, configure the network to 192.
The left column shows all stored projects in equipment. Set the storage path first. Choose relative project based on capture data and time, click “>>>” and the selected data will be moved to the right column. Finally, click “Copy” and the software will automatically download both POS and laser data into storage path folder. Tips: ▪ Make sure the IP address is configured correctly, otherwise the “DataCopyTool” software cannot be opened.
abnormal shutdown of the device. ▪ For camera data copy, remove the camera memory card and copy pictures with card reader. Note, this memory card can bot be formatted and also can not delete internal folder. 6.2.3 Data Structure BASE: Save base data which recorded by GNSS receiver in static mode. CCD: Store pictures raw data. LAS: Store raw data of laser scanner. PARA: Store parameter files (include default and new files which create during process) ROVER: Store GPS and IMU data.
7 LiDAR Turn Off ▪ Before turning off equipment, please make sure the project is already stopped. ▪ Long press equipment “ON/OFF” button to turn off equipment until the light is out and buzzer is ring. ▪ After the buzzer is stop ringing, disconnect the power supply cable to finish turn off.
