  • Unique feature: Dynamic Stabilised Active Mount (DSAM)

    Crab_Angle_1

    The TopoDrone-4Scight features revolutionary Dynamic Stabilised Active Mount (DSAM) which compensates for “aggressive” flight movements, eliminating camera geometry errors during flight and thus removing the need to correct these in post processing data.

    No_Crab

    The Dynamic Stabilised Active Mount (DSAM) is designed with an integrated protective door which is closed during launch and landings, and can be activated at any time of the flight sortie.

  • Unique feature: Direct Georeferencing Solution L1/L2/L5/GLONASS/COMPASS(BeiDou-2)

    Direct-Georeferencing-Solution-JPEG-Q60-480x340-Inverted

    The TopoDrone-4Scight is easily upgradable for Direct Georeferencing L1/L2/L5/GLONASS/COMPASS(BeiDou-2) – mapping with no ground control!

    We have developed our Direct Georeferencing Solution which uses L1/L2/L5/GLONASS/COMPASS(BeiDou-2) on board of our TopoDrones, synchronised to the nano-second of the camera shutter. It ensures accurate positioning of each photograph.

    Differential GPS post-processing is then used to obtain the accurate camera positions which are then used in photogrammetric aerial triangulation.

    Benefits:

    • mapping larger areas (which may require several flight sorties to cover the full area of mapping)
    • reduction/full elimination of ground survey control points: when ground survey control needs to be reduced to only one or two points or when ground survey control points are not used at all
    • mapping “challenging” terrain: when the terrain to be mapped is more “challenging” for the type of coverage and therefore the pixel matching (such as dense forests, coastal mapping, etc.)

    Outcomes:

    • dramatic improvement in mapping accuracy
    • significant reduction of processing time
    • highest quality of overall photogrammetric mapping

  • Unique feature: Stereo mapping and 3D “heads-up” digitising

    Stereo mapping and 3D “heads-up” digitising by DroneMetrex

    Our Drone Mapping System provides a unique opportunity for stereo mapping: from the start the imagery can be viewed and digitised in true 3D “heads-up” mode.

  • Output products

    Output products include: high density point cloud, accurate imagery (digital orthophotos, digital seamless orthophoto mosaic of the whole area), volumes and profiles, Digital Terrain Model (DTM) – Bare Earth, Digital Surface Model (DSM), contours, 3D photogrammetric “heads-up” feature digitising, digitised linework (kerbings, roof tops, GIS assets, etc.), which can be fed into the design and planning process for industrial applications:
