Combines advanced technology with upgraded high-definition Camera, IMU, and 4G integration, M20 can quickly capture the site in images and measure points either in the field or later in the office, it enables you to measure what you see, such as obstruction points, obstacle points, dangerous points, and map hundreds of points with survey-grade accuracy within minutes and capture the scene quickly and decide what should be measured later–even if the scene subse- quently changes or disappears.

Key Features

VR for Superior Visual Surveying

The M20 achieves real-time& non-contact measurement via camera, enabling precise measurements at points where signals are blocked or where access is difficult or unsafe. Its advanced cameras extract survey-grade 3D coordinates from real-world video, maps hundreds of survey-grade accurate points within minutes, providing higher efficiency and reliability.

3D Modeling

The M20’s video photogrammetry algorithms enable 3D modeling of buildings and facades. It effectively fuses drone and GNSS RTK data to efficiently perform 3D modeling over large areas. Additionally, the M20 is compatible with indus- try-standard 3D modeling software.

AR Stakeout

Visual positioning eases point finding by overlaying design files onto real scenes, enhancing stakeout efficiency. A high-performance HD camera achieves high accuracy with precise signal tracking. The 360-degree AR stakeout seam- lessly switches between the handheld controller and rover, ensuring fast and accurate stakeout experiences.

Calibration-Free Solution

Equipped with 120° calibration-free IMU technology in a compact body, it complements the laser's outstanding performance, extending the M20's application range to locations that traditional RTK systems cannot reach, open- ing up new horizons for product applications, enhancing customer satisfaction and boosting operational efficiency.

Longer Working Distance

Equipping the MeridianLink protocol internal radio offers 15km working range and increases flexibility. By eliminating the need for an external radio, the M20 becomes more lightweight, less complex, and more portable, which can lead to increased efficiency and convenience in the field.
