viDoc RTK Rover for iPad Pro 11"+ Pix4Dcatch

Multiple options for accurate point measurement

Measure with the laser, photogrammetry, or attach it to a surveying rod.

Measure obstructed points

Complete data collection without missing anything that may be obstructed by objects like trees or overhangs.

Accurate and safe measurement methods

Get your measurements and reduce risks - cut unnecessary trench visits, etc. Make data collection safer.

The viDoc RTK rover for PIX4Dcatch:
Accurate surveying with a mobile device

Easy field-to-finish workflows

Easy digitalization with Pix4D software that can measure single points or create line work from data capture.

RTK positioning rover for 3D scanning

viDoc RTK rover pairs with the PIX4Dcatch to geotag images of the 3D scan in real-time using NTRIP services

Enhanced mobile data collection

viDoc connects to over 600 channels (including all major constellations such as GPS, GLONASS, Galileo, etc.) which results in convergence in under 5 seconds.

Replacing complex workflows

Ground surveying equipment like laser scanners can be expensive, bulky, and highly technical. Drones can be restricted by regulations. Overcome the obstacles with a handheld rover.

A complete, accurate workflow in your hands

The viDoc, the iOS device, PIX4Dcatch, and PIX4Dcloud. An end-to-end solution that gets measurements with an absolute accuracy of less than 5cm.

Intuitive feel and structure

Easy for anyone to collect points or complete an accurate 3D scan. The handheld rover combines with mobile software to create digital twins as fast as possible.

What is the viDoc RTK rover?

The viDoc RTK rover is a device that can be mounted onto Apple iPad Pro devices. The rover, synchronized with Pix4Dcatch, geotags images with RTK accuracy in real-time, while connected to any NTRIP service, allowing absolute accuracy in 3D photogrammetric scanning.

Extensive research has revealed that it is possible to achieve 3D models with an absolute geolocation accuracy of less than 5 cm.

Conceived by viGram GmbH., a German company led by professional surveyors, the viDoc RTK rover is designed with an eye for accuracy and works with Pix4Dcatch for image acquisition. The hand-held RTK rover is a replacement for more expensive ground surveying equipment that does not compromise on accuracy to achieve 3D, actionable results.

How to use the Pix4Dcatch with viDoc RTK rover?

Basic requirements:

• Pix4Dcatch iOS app on the your iPhone Pro
• viDoc RTK rover.
• NTRIP service subscription.
• Internet access.
• PIX4Dmatic, Pix4Dmapper, or Pix4Dcloud (Advanced) license for processing.

Once the latest iOS version of Pix4Dcatch is installed, select the viDoc RTK via Bluetooth settings. More information in the How to use Pix4Dcatch with viDoc RTK rover article.

How are the images captured in Pix4Dcatch synchronized with the viDoc RTK rover?

The image acquisition in Pix4Dcatch is independently done from the recording of the GNSS data from the RTK rover. When the capture is complete and the project is saved, the geolocation information from the rover is tagged to the corresponding images based on the image timestamps. The orientation of the images is computed based on information from the AR tracking. In case part of the GNSS data has low accuracy (for example due to poor satellite visibility), relative AR positioning is used to improve the positions and accuracy.

Can I generate a 3D model or 2D map in a coordinate reference system of my choice using Pix4Dcatch+viDoc?

Yes, you can select the coordinate system when uploading to PIX4Dcloud/PIX4Dcloud Advanced, in PIX4Dmatic or Pix4Dmapper, to get the 3D model or 2D map in a coordinate reference system of your choice. You can also transform the image geolocation in the desired coordinate system with third-party software.
