2G Robotics’ ULS-500 Interfaced with QINSy

2G Robotics announces that the ULS-500 underwater laser scanner is now compatible with the QPS hydrographic data acquisition, navigation, and processing software, QINSy.

The QINSy suite can be used for various types of surveys, ranging from simple single beam surveys up to complex offshore construction works, the company said.

Recently, 2G Robotics performed a structure inspection demonstration with a customer using ULS-500 system. The ROV cage was scanned to simulate structure inspection and two flanges were attached to the cage as a mock-up to simulate spool metrology.

To collect the data in profile mode, the ULS-500 published data in LAS format into QINSy. QINSy was interfaced directly to the ROV sensors and the ULS-500 to correct for ROV altitude in real-time and geo-reference using INS position updates aided by Doppler in order to position the ULS-500 data and build a complete 3D model.

Richard Hill, Sales and Marketing Director at QPS, explains that QINSy enables you to “simultaneously survey with MBES, camera, and laser scanner. A key objective for QINSy is to save time in processing. By providing tools for real-time QA/QC and on-the-fly correction for sensor offsets, altitude, sound velocity refraction, data flagging and tide/height, DTM points are derived as the survey proceeds. The multi-layered sounding grid data shown in the Navigation display is populated with corrected DTM points on-the-fly, giving the operator a complete view of what has been surveyed.”
