UAV Photogrammetry

UAV Photogrammetry : This video shows an application of an Infinite Jib Surveyor Craft. The Surveyor flew over an Open-Pit mine in Quebec to capture the photos used to create the 3D image. Once created the 3D image can be used to do volumetric calculations of the area covered.

Advanced True Orthophoto from Photogrammetry and LiDAR Integration

Advanced True Orthophoto from Photogrammetry and LiDAR Integration

This flythrough over The University of Calgary shows the successfull integration between LiDAR data and high resolution true-orthorectified aerial photographs. This is part of a PhD research that involves integration of LiDAR, Photogrammetry, and GIS for improved realistic 3D visualization. Well there is a number of sw used from point to point. The Building DBM modelling was semi-automated using an extension ...

Is photogrammetry as accurate as lidar?

Is photogrammetry as accurate as lidar?

Elmer Bol, new director of reality capture at Autodesk and founder of Alice Labs, spoke at SPAR Europe in November about the increasingly sophisticated technology that is allowing the accuracy of point clouds created by photogrammetry to approach the accuracy of terrestrial lidar and laser scanning.

Photogrammetry: Which is better, grid flight or ROI?

Photogrammetry: Which is better, grid flight or ROI?

“At our most recent sUAS mission we utilized the Mission Planner ROI (Region of Interest) feature to capture aerial images of the subject. The ROI datum allows the user to create a fixed centroid position to orient the camera and figure an equal distance from a point for the flight path. Our goal was to solve some of the distortion ...

Light Detection and Ranging (LiDAR) Returns

Light Detection and Ranging (LiDAR) Returns

This animation demonstrates how a discrete return LIDAR system records information as light travels through an object, like a tree. The NEON project will collected and offer free discrete return and full waveform LiDAR data for 30 years across it’s field sites. It will also offer derived data products like canopy height models and elevation data.

PHOTOGRAMMETRY: Eyes in the Sky

PHOTOGRAMMETRY: Eyes in the Sky

When Hurricane Irene hit North Carolina, the Photogrammetry Unit of the N.C. Department of Transportation knew it would be called into action. When the storm passed, the Photogrammetry Unit took to the skies from Raleigh-Durham International Airport in a Beechcraft C-90 aircraft mounted with a high-resolution digital camera. The group has flown missions at about 7,500 feet from Ocracoke to ...

Aerial Photogrammetry with Hexakopter

Aerial Photogrammetry with Hexakopter

In short, we placed Ground Control Points (GCPs) around a man-made ponding area at roughly ten meter intervals (40 x 30 m in total area). The GCPs were shot in with a deferentially-corrected GPS (0.1 m horizontal and 0.2m vertical resolution) and with a Total Data Station (0.03m vertical and horizontal resolution). We then flew the Hexakopter at 40m above ...
