Homegrown photogrammetry solution for a global industry

By on 19 May, 2016


Pioneering Perth drone manufacturer ScientificAerospace together with mapping experts DroneMetrex in Adelaide have developed a unique photogrammetric mapping solution that will revolutionise the geospatial industry.

Building on the advantages of ScientificAerospace’s industry-proven experience over eight years in six continents, their uniquely designed and technically advanced multi-rotor drone is a perfect synergy with DroneMetrex’s world-leading mapping accuracy technology to produce the world’s most accurate, safest and easiest complete photogrammetric mapping system – the TopoDrone-4Scight (TD-4Scight).

The TD-4Scight easily collects photogrammetric mapping data at an accuracy of 20mm horizontal and better than 25mm vertical. It is aimed for use in a wide range of industries including surveying, urban mapping, civil engineering, mining, agriculture, bridge and dam wall mapping, post disaster mapping, waste management, recycling and other industries.

The world’s most accurate, safest and easiest complete photogrammetric mapping system

ScientificAerospace Managing Director Richard Pace said the TD-4Scight will be invaluable for many of his customers.

“The new mapping system is very affordable and it is easy to use without complicated setup. It requires minimal training and it is easy to transport,” he said.

The TD-4Scight is capable of mapping without ground control points. The TopoDrone-4Scight goes with PPK Direct Georeferencing Solution which uses positioning with multi-GNSS, synchronised to the nano-second with the camera shutter.

The accurate synchronisation is very important to achieve high mapping accuracies. Differential GNSS post-processing is used to obtain the accurate camera positions that are required for the photogrammetric aerial triangulation. It significantly improves mapping accuracy for larger projects as well as quality of the photogrammetric mapping.

At the same time PPK Direct Georeferencing Solution significantly reduces time for the final photogrammetric aerial triangulation and data processing time.

The TD-4Scight uses modern compact digital camera technology, with a calibrated Hasselblad glass lens housed in a revolutionary Dynamic-stabilised Active Mount (DSAM), allowing for mapping in either nadir mode, landscape mode or zenith mode (“pointing-up”).

The TD-4Scight mapping drone is being developed to be used with interchangeable sensors including thermal and HD video.

The TD-4Scight system is completed with the inclusion of the “4Survey” flight planning and autonomous flight control software, along with “4Survey-Precision”: the GPS post-processing software enabling mapping with minimal survey ground control requirements.

Both 4Survey and 4Survey-Precision were specifically developed for the TD-4Scight.

Mr Pace said he was excited to be working with C. R. Kennedy Survey as the exclusive reseller of the TD-4Scight in Australia.

ScientificAerospace and DroneMetrex also have formalised sales distribution agreements with distributors in New Zealand, South Korea, the UAE and Germany.

Mr Pace said agreements would be in place with exclusive distributors in the United States and Great Britain in coming months.
