Efficient Camera Gnss Vision Survey And Stakeout 3D Modeling Chcnav i93

Short Description:

1. The i93 is an extremely versatile receiver that integrates the latest GNSS, Auto-IMU, RTK, and premium dual-camera technologies.

2. By incorporating CHCNAV’s latest visual navigation and stakeout technology, the 3D visual stakeout feature provides ease of use and comfort.

3. The i93′s video photogrammetry technology enables accurate visual surveys, simplifying point measurements without the need for complex offset methods and making it possible to survey previously hard-to-reach, signal-obstructed, and hazardous locations.

4. The i93 can also be used to complement aerial surveys generated from oblique imagery since its data is compatible with the most popular 3D modeling software.

1408 Channels, Istar And Hybrid Engine

1. The i93 GNSS receiver features 1408 channels that track full constellations and frequencies, it’s powered by an integrated RF-SoC processor and iStar CHCNAV technology.
2. With a 15% gain in survey-grade GNSS RTK performance in challenging environments, the i93 delivers reliable and accurate positioning data.
3. The built-in hybrid engine and proprietary narrowband interference mitigation technique boost GNSS data quality and signal tracking capabilities by more than 20%, ensuring the best possible GNSS RTK performance for any application.

Visual Navigation And Stakeout

1. The i93 integrates star-level cameras to provide an immersive 3D visual navigation and stakeout experience.
2. 3D visual capabilities are also available for line stakeout and CAD-based map stakeout, making operations similarly effortless, intuitive, and efficient.
3. This simplifies the stakeout process, allowing for quick completion in seconds and increasing efficiency by up to 50% for less experienced field operators.

Visual Survey And 3D Modeling

1.The i93 combines GNSS, IMU, and two premium global shutter cameras with video photogrammetry technology.
2.The i93 delivers survey-grade 3D coordinates from real-world video capture in seconds, making it easy to survey previously hard-to-reach, signal-obstructed, and hazardous points in the field, such as under overpasses, under eaves, and near power poles.
3.With its dynamic panoramic video capture and automatic image matching, the i93 improves productivity by up to 60%.
4.Automatic high-speed continuous shooting and adjacent image generation with up to 85% overlap ensure high processing success.
