· Before photogrammetry, test the tilt measurement function. Measure a point and perform stake out. If the stake out accuracy is within 2cm, the tilt measurement is functioning well.
· After photogrammetry, check the accuracy. Measure the photogrammetry point again with regular tilt measurement. Use the "Great-circle distance" function to calculate the distance between the two points. If the distance is within 2.5cm, the measurement accuracy is basically acceptable. Then you can further verify using point stake out.
· Taking photos. Move around the object as the software suggests and take at least 5 photos.
· Selecting points. After taking photos, enter the photo gallery to choose and save suitable points. Note: Points with great color contrast to surrounding objects are preferred to prevent calculation failures.
· Avoid measuring in dim environments.
· Avoid measuring in extreme weather like heavy rain, dense fog, or heavy snow.
· Avoid measuring near high - rise buildings.
· Check the satellite count and differential delay. There should be over 25 available satellites, with a differential delay of no more than 3 (preferably maintained at 1). These two status can be directly viewed at the top right corner of the software.
· Check the communication connection. The photogrammetry software and receiver must communicate via Wi-Fi, which can be checked in the communication settings.
· Check the inertial navigation (IMU) status. If it's unavailable, the measurement interface will show a warning in red.
· Strong impact of the pole tip on the ground can affect the IMU data of the receiver. Walking with the pole tilted after the IMU is activated may prevent the IMU from accurately sensing the initial posture.
· Before laser measurement, test the tilt measurement function. Measure a point and then perform stake out. If the stake out accuracy is within 2cm, the tilt measurement is functioning well.
· After laser measurement, verify the accuracy. Compare the points measured with the laser with those measured using point - to - point survey. Use the "Great-circle distance" function to calculate the difference between the two points. If the difference is within 2cm, the measurement accuracy is basically acceptable. Then you can further verify using point stake out and laser stake out.
· Initialization. Each time you enter the laser measurement interface, initialization is required, including for the IMU and the laser.
o The IMU can be initialized by gently shaking the staff back and forth.
o For laser measurement initialization, first check that the measurement interface can display distance properly, then walk straight for about 5 - 10m.
· Time limit for measurement. Measurement should be completed within 15 seconds after initialization. If it exceeds 15 seconds, re - initialization is needed.
· Measurement distance. To ensure a laser measurement accuracy within 2.5cm, the measurement distance should be within 5m.
· Stability of the laser aiming point. When measuring, try to keep the laser point steadily aimed at the target point without shaking before taking the measurement.
Software common problems and solutions
· Only run the measuring software on the controller. Other software might consume resources needed for photogrammetry, causing the measurement to crash or lag halfway.
A. Check the PDOP limit and height cutoff angle.
B. Ensure the satellite reception environment is good.
A. Click "Search Bluetooth Devices" again.
B. Ensure that the location information on the device is enabled.
C. Check if the device is turned on.
D. Verify if the Bluetooth name of the device has been changed.
E. Ensure that the device is not too far away from the device.
A. Re-search for Bluetooth and connect again.
B. Pairing is required for initial connection.
A. Check if the NFC on the device is working properly.
B. Verify if the NFC tag content matches the actual Bluetooth address of the device.
C. Confirm if the NFC tag is locked.
A. Check if the surroundings meet the reception conditions.
B. Check if the registration code has expired.
C. Verify if there are any regional restrictions.
D. Ensure that the Bluetooth is connected.
E. Check if the satellite system is turned off
Go to "Configuration" - "Instrument Registration" - Input the registration code - Click "Register"
Go to "Projects" - "About Software" - "Software Activation" - Enter the registration code - Click "Activate"
A. Check if the handbook has internet access.
B. Verify the correctness of the CORS IP address, port, username and password.
A. Check whether the device is inserted with SIM card.
