Hexagon adds visual positioning technology to its survey-grade GNSS RTK rover

Information from Hexagon

Hexagon’s Leica GS18 I is equipped with all the functionality of the GS18 T (calibration-free, tilt-compensating GNSS solution immune to magnetic disturbances) plus survey-grade visual positioning.

Through sensor fusion of satellite (GNSS), motion (IMU), and image (camera) technology, the GNSS RTK rover enables the measurement of points from images. The ability to capture and measure sites via images goes beyond the advantages of the GS18 T, which introduced the ability to measure points in spaces that cannot be measured with vertical poles, such as building corners, walls, and points underneath obstacles (e.g., cars). With the Leica GS18 I, professionals can now map areas that are difficult to reach physically, such as trenches, high power lines and busy roads, or blocked from GNSS signals, such as areas underneath bridges or canopies – all safely and effortlessly from a distance.

The Leica rover can measure hundreds of points within minutes. Integration with Leica Captivate field software allows onsite point measurements and quality assurance from the field. Further measurement of the captured images is supported by integration with Leica Infinity office software, which also enables the creation of automatically registered and referenced 3D point clouds from the images in standard export formats for use in a variety of point cloud software.
