Fast and reliable site documentation for future use

3Dsurvey RTK videogrammetry is a modern approach in surveying and mapping, leveraging the dynamic nature of video to create 3D representations of physical spaces.

A well-documented site is a valuable asset for future use and effective planning and project management. Especially when positions of specific elements are needed.

A fast and efficient approach to site documentation of various construction and engineering projects involving pipelines and underground grid.

Extract the exact measurements, monitor the width and the depth, calculate the volume and extract profile lines.

3Dsurvey SiteScan app and mobile RTK support

RTK Videogrammetry module includes the 3Dsurvey SiteScan app for Android, and mobile RTK support that significantly increases the precision and reliability of the measurements and 3D models produced from video. This is done using corrections from a reference station to improve the accuracy of the satellite positioning data, overriding the often-inaccurate GPS data provided by the mobile phone or tablet.

FOCUS ON THE CENTER

  • Keep essential features in the center of the camera sensor
  • Edges can distort images and reduce clarity


WALK SLOWLY

  • Slow movements minimize motion blur
  • Telemetry data updates only once or twice per second


AVOID REPETITIVE FOOTAGE

  • It might confuse surface recognition
  • It might lead to duplicated points or misaligned surfaces


PLAN YOUR PATH

  • Avoid obstacles and ensure safe recording
  • Ensure you capture all the necessary details


BE AWARE OF REFLECTIVE SURFACES AND SHADOWS

  • Reflective surfaces like windows or water cause distorted results
  • Strong shadows can result in a loss of details and information


AVOID WALL PAINTING MOTION

  • Walk during the recording, don’t stand in one place (no painting motion)
  • Rather step back to capture a wider frame
