ViDoc is a mobile measuring device that turns an iPhone or iPad into a powerful photogrammetry device.
How does it work?
1. The ViDoc module is a dual-frequency GNSS receiver that connects to a base station or a network of RTK base stations;
2. The device receives corrections to coordinates from base stations in real time;
3. These coordinates are correlated with the images and lidar point cloud from the phone or tablet with high accuracy in the PIX4Dcatch professional app.
An additional bonus is that the device is equipped with rangefinders that measure the distance to the ground and the object. The set of technologies used brings positioning during shooting to a new level.
Terrain shooting takes place in the full-time free Pix4Dcatch application. The device independently determines the position of the pictures and the speed of photography according to the parameters we set. The user only needs to move at a uniform speed, and the system will scan automatically. In addition, the application provides an opportunity to view the position of the images and familiarize yourself with the demo view of the object under study. The user can immediately determine whether the object was completely photographed, whether there are certain gaps, and what will have to be taken into account during processing.
The received data can be downloaded to a computer and processed in the PIX4Dmatic or Mapper software, or uploaded to the PIX4Dcloud cloud environment.
For this application, PIX4Dcloud has no limit on the number of photos.
To determine the correctness of DroneUA measurements, experts from System solution were involved in the study .
Our colleague Mykhailo Turyanitsa compared the data obtained using the ViDoc device with ground reference points obtained by the Leica GS18 I RTK rover. Research materials are available at the link .
The average deviation was up to 5 cm, excluding several points.
The great advantage of working with the ViDoc module is the speed of work: 14 hectares were processed in 3.5 minutes of field work, 7 minutes were spent on data processing, and as a result - complete information about the shooting object.

Conclusions:
Pix4Dcatch bundled with viDoc is a powerful yet simple application that allows you to quickly and safely measure complex objects and their parameters.
It is important to note that when performing this technology, it will always be possible to perform additional measurements in the office without having to go out into the field again.
For details and the possibility of test use, contact our experts - they will be happy to provide the necessary information.
