    Inertial Labs has added a new scanning and mapping solution to its Resepi line, the Resepi Teledyne Optech CL-360-HD. The device has a powerful four-return laser and increased range of up to 750 m, making it ideal for mobile mapping, forestry and crack detection in critical infrastructure areas such as airport runways.

    Resepi is a sensor-fusion platform designed for accuracy-focused remote sensing applications. Resepi utilizes a high-performance Inertial Labs INS and a high-accuracy dual antenna GNSS receiver, integrated with a Linux-based processing core and data-logging software. The platform also provides a WiFi interface, optional imaging module, and external cellular modem for RTCM corrections. Resepi can be operated by a single hardware button or from a wirelessly connected device via a simple web interface.

    Resepi, equipped with Teledyne‘s CL-360HD lidar, offers various laser scan speeds and frequencies, allowing users to tweak the settings to match their individual needs.

    A new blog offered by Inertial Labs discusses the scope of work to turn lidar point-cloud data collection into actionable deliverables. The blog, “Providing Actionable LiDAR Point Cloud Deliverables and the Inertial Labs RESEPI” by Luke Wilson, is also available as a downloadable PDF.

    The blog introduces lidar and creation of point clouds, then discusses the use of GPS-aided inertial navigation systems (INS). “A lidar point cloud is the product of sensor fusion across a GPS-aided INS and a lidar scanner. Each sensor plays a critical role in how a lidar payload functions and the applicability of its point cloud output,” explains Wilson.

    Wilson describes complications with converting datum reference frames, both traditional and reference ellipsoid such as WGS84. He also discusses projected coordinate systems. He concludes with analysis of the data using point classification — the foundation to create models including digital terrain, surface and elevation models (DTM, DSM and DEM respectively).

    Finally, Wilson explains how Inertial Labs’ RESEPI is a quick and efficient way to generate models of an environment, including in fields such as construction and utility management.

    RESEPI stands for REmote SEnsing Payload Instrument, Inertial Labs’ complete multiplatform, multisensor lidar and RGB payload solution for such remote sensing applications.
