New model CHC i89/X15 GNSS GPS RTK with video survey and 0-60 degree tilt survey IMU.
X15 RTK is a new product that integrates CHC video photogrammetry technology, supporting video measurement and 3D modeling. It quickly and efficiently obtains high-precision 3D coordinates in batches from live videos, achieving what you see is what you measure, and can be measured while walking. Support AR real scene navigation and immersive real scene 3D lofting, with no getting lost and one shot in place, improving efficiency by 50%. Upgraded the anti daze design of the center pole, combined with following the lofting, the lofting base map rotates with people, and the navigation is viewed from the first perspective, without the need to struggle to identify direction and distance. Upgraded Huace Yizhang Network ™ The same origin 2.0 algorithm as the cloud has improved the fixed rate to 96%. Support non-invasive super inertial navigation, no initialization required, point to point measurement, and reliable accuracy. At the same time, it supports continuous testing without network interruption and can be tested
