In the Remote sensing and forest inventory course we allways has a demo of different sensors and platforms avialble for the students in the Ljungberg laboratory. This year we brought the new handheld laserscanner from GeoSLAM, in addition to the drones (camera and Lidar) and terrestrial laser scanner. The image is a view of the … Continue reading Field visit RS course: Testing the new GeoSLAM hand laser scanner

From the 1st of July there will be new regulations for operating drones in the air space. The regulations will be the same within EU. In order to inform the drone users within the university and to discuss how we should implement the new regulations in the organisation we had a internal seminar, however the … Continue reading SLU internal seminar on new regulations for flying drones

As part of a Design-Build-Test course, five engineering students are building a albedometer sensor system for the new drone in the Lab. The albedometer will consist of two MS-80U pyranometers from EKO instruments and a lidar unit (LIDAR Lite v3) from Garmin. Albedometers are mostly used to measure the reflectance of earths surface, using two pyranometers: one … Continue reading Albedometer drone project ongoing

Victor Kingstad och Mårten Tovedal presented their master thesis projects at the RIU conference in Skinnskatteberg, 13-14 November. The conference is an annual event gathering people from forest planing and forest inventory. Both students are doing drone based forest inventory. Victors topic is forest cleaning need assessment using rapid orthophotos. Mårten is looking at methods … Continue reading Students present Master thesis projects at RIU conference

The lab has developed a software to view and analyze point clouds in Virtual Reality. The application is written in Unity and supports only HTC Vive. We have also released the source code we have written ourself and you can modify and add support for other headsets. The application will right now not be further … Continue reading Point clouds in virtual reality

Placing ground control points (GCP) when performing flights with drones can be a very time consuming task which is why we now have placed permanent GCPs around the property at Innertavle. There is a total of 11 GCPs placed around the boarder of the property. The GCPs helps in the post process by being able … Continue reading Permanent ground control points in Innertavle

The 13th of February we will start with the first workshop for this semester. Previously we called this open-lab, but now we prefer to call it workshops. The idea with the workshops is start at 13:00 with a short introductory presentation of a remote sensing topic, for example use of drones in forestry. The presentation … Continue reading Workshops on Wednesdays

Today we release the first beta version of our application to view and analyze point clouds in Virtual Reality. We have named the application PointCloud XR and you can read more about the development and download PointCloud XR. Please add a comment on our Facebook page about your thoughts after you have tried it! In … Continue reading Beta release of PointCloud XR – A free viewer for point clouds in Virtual Reality

Now we continue with the second half of the course. The first part gave an overview of drone systems and regulations as well as drone flying and flight planning. Now we continue with processing collected images to geographic data, e.i. ortho images and 3D point clouds and then how those products can be transformed into … Continue reading Course in Drone based Inventory, part 2.

The course aim is to provide students with knowledge how to conduct drone based image acquisition and forest inventory. An introduction will be given on drone systems and regulations as well as practical knowledge on how to operate drones to acquire images for mapping.  The first part will focus on getting the images. The second … Continue reading Course in Drone based Inventory, part 1.
