2017年5月27日 · With a GSD of 0.3mm, if you could achieve a shutter speed of 1/1000 (unlikely) then a velocity of even 0.3 metres per second (300mm/sec) would give you motion blur of 1 pixel !! At 20 metres altitude an angle change of 0.9deg/sec would give you motion blur of 1 pixel !! You will need a very, very steady platform.

2024年5月23日 · Users can precisely control parameters like Ground Sampling Distance (GSD) and overlap, ensuring accurate data collection. Additionally, FlytBase's Flinks enable seamless integration of third-party apps and systems, further enhancing the versatility and capabilities of the DJI Dock 2 for various applications beyond mapping and surveying.

2018年3月27日 · If the GSD would be decreased, flight altitude will also be decreased. The true focal length will remain constant; therefore, the drone’s flight speed has to be decreased or the speed of the shutter increased (exposure time decreased). The minimal trigger interval for DJI Phantom 4 is 3sec, therefore the flight speed has to be decreased.

2014年10月21日 · DroneDeploy is launching the first drone software capable of creating orthorectified maps in real-time. Farmers, surveyors and search and rescue teams typically had to wait for 4-6 hours for maps to be created out of drone imagery, but now can start making decisions with data as it’s collected live. Tim VanDermyden, CEO of Stratos Aerial, a Surveying Drone company explains “Typically data ...

2013年2月10日 · Hi, the pixels between images are the same size. ~10 cm GSD. Each orthomosaic (VIS and NIRVIS) scene is the same size and GSD. 10772 x 12442 pixels. The flight was completed with two different cameras and the geo-referenced orthomosaics were generated from the same flight.

2014年12月1日 · I work for a heavy / highway construction company, we are looking into survey drones for topographic surveying, as well as point references and 3d mapping etc. I bought a dji phantom when they first came out, weve been using a dji vision plus for aerial photos of our jobsites. Consider me a newb for the surveying end of this, but correct me if I'm wrong, but for surveying, don't I just need an ...

2016年12月1日 · I've just seen cool tests from Jeff Taylor and his Event 38. They integrated Emlid's Reach in E384/E386 mapping drones and verified processed data accuracy using data from Trimble R6 Model4. With the Emlid Reach RTK GPS Receivers now available, we’ve been conducting tests to determine their accuracy and working on the integration into the E384 and E386. The goal was to determine relative, or ...

2017年3月27日 · This is normally done with a hotshoe adaptor or some interface with the camera. Going to be tough to do without some work using this camera. At the end of the day the camera still is limiting on what GSD and image quality you can achieve so the final product is going to be dictated by that I think.

Hi guys, We would like to share with you very simple find we did during our operations. Making reusable Ground Control Points (GCPs) for aerial photography and photogrammetry. We spend a lot of time testing and tuning our Universal Ground Control Software U[g]CS in a real world scenarios. For aerial photography and photogrammetry you can rely on modern software like Pix4D, Acute 3D and other ...
