Can Precis-BX316 work well for aerial photogrammetry with UAV without the need for ground control points(GCPs)?

Can Precis-BX306 work well for aerial photogrammetry with UAV without the need for ground control points(GCPs)?

Yes, the following solution can be used to replace the GCPs:

You can setup a base with our Precis-BX306, and then transmit RTK corrections from the base. After the corrections are received, it will output accurate (cm-level) positioning and heading info. In the application of aerial photogrammetry with UAV, after the camera take a picture, it will send a pulse from the PC (Prontor-Compur connection) port to the receiver, the accurate position (cm-level) will be saved.

The photos and their positions will be input to the mapping software (eg, PIX4D or Agsoft) to get an accurate map.

Do I need a specific camera to work or any camera?

No specific camera is needed; you can use any camera which has a PC (Prontor-Compur connection) port. And the synchronization between the shutters to the flash must be enabled. When the camera is taking a photo, a pulse is sent to the receiver through the PC port. The exact time when the photo is taken will be saved for post-processing.

Three Typical Situations of Earthwork Measurement

Three Typical Situations of Earthwork Measurement Tips for earthwork measurement under different circumstances with Tersus Oscar GNSS receiver and NUWA APP Earthwork calculations are essential in many survey projects, but the complexity of measurement and calculations causes many new engineers headaches. In general, earthwork calculation is divided into two parts: excavation and filling, which can also be simply understood as volume and capacity calculation. The following are the Tips for using the Tersus Oscar GNSS receiver and NUWA App for earthwork measurement under different circumstances. The powerful earthwork calculation function of the NUWA app can calculate the result and quickly; you only need to import the survey points and then input the reference altitude. Notes for measurement: When measuring points, we should measure as many points on the surface of the object as possible. The density of survey points needs to be strengthened in places where the terrain changes sig...
