This method requires the use of a Survey Trolley (RLACS173-XXX where XXX represents the frequency of the Base Station if being used).
When using the Survey Trolley, data is recorded at 10 Hz and provides an accurate representation of the parking bay.
Surveying a Parking Bay with Straight Lines
- Assemble the Survey Trolley and mount the VBOX, radio/NTRIP modem, ACS112L Li-Ion battery and VBOX Manager into the surveying back pack.
Assembly instructions can be found here.
- When the VBOX displays 'RTK Fixed' you can start to survey the parking bay.
- Place the centre line of the Survey Trolley over the inside edge at the entry point of one of the bay side lines.
Note: It doesn't matter which bay side is recorded first.
- Using VBOX Manager, select ‘START’ to begin the recording and start walking with the Survey Trolley along the inside edge of the bay side line, attempting to keep in as straight a direction as possible.
Note: Walking speed must exceed 0.8 km/h.
- Once you have crossed the back line of the bay, making sure to go beyond it by a small amount, select ‘STOP’ on VBOX Manager and then 'KEEP' to save the file.
- Repeat the process above for the other bay side line.
- Now you need to record the back line of the bay by placing the centre line of the Survey Trolley over the inside edge of the rear line of the bay, making sure to locate it before the bay side line by a small amount.
- Repeat the process above to start recording the line.
- Once you have crossed the other bay side line, making sure to go beyond it by a small amount, select ‘STOP’ on VBOX Manager and then 'KEEP' to save the file.
IMPORTANT - The recorded bay sides must overlap each other in order for VBOX Test Suite to recognise the parking bay entry point. The recorded parking bay lines should be similar in layout to the parking bay image below.
- Remove the CF card from the VBOX and insert in to a PC.
- The parking bay sides are now ready to be loaded in to the Park Assist plugin within VBOX Test Suite software.
Note: Recorded bay side .vbo files can be renamed for ease of use if required, e.g. Left Lane, Right lane, etc.
