Photogrammetry out of the Dark Room

GIM Interviews Remi Jean, President DVP-GS and Vice-president and Partner Groupe ALTA
DVP-GS is a small Canada-based business founded in 1988 to market software products resulting from research into digital photogrammetry at Laval University. This month’s interviewee, Remi Jean, president DVP-GS, is very optimistic about the future of photogrammetry: "It is only a question of time before we see a significant increase in the demand for quality data. Photogrammetry has definitely come out of the shadows - or the dark room!" What are your main types of products and how much does each contribute to your turnover? We hold the specialised niche of vectorial-data extraction from aerial, satellite and non-conventional geospatial imagery.... (read more)

Photogrammetry and Laser Scanning on Single Aircraft

Diamond Aircraft, Austria, has introduced the new DA42 GEOSTAR that enables the collection of laser scanning and photo-grammetry data during one single flight. The team of Diamond Airborne Sensing (subsidiary of Diamond Aircraft) announced it has succeeded in perfect sensor integration on the DA42 MPP, the most economic remote sensing platform worldwide. Both systems are integrated with sufficient resources for fuel and flight crew. Hence the GEOSTAR is able to complete incredible 10-hour survey flights with a range of up to 1,042 NM, equivalent to the flight route Copenhagen - Barcelona. At an altitude of 10,000 feet it can even... (read more)

Photogrammetry – Recent Developments and the Way Forward

Over the past few years, photogrammetry, remote sensing and spatial information science have witnessed great achievements, mainly due to societal, political, environmental and technological changes worldwide. Human mobility has significantly increased due to population growth, climate change and globalization. Photogrammetric innovations have also been strongly influenced by the developments in information and communication technology (ICT), computer vision and robotics. Moreover, with the usage of active remote sensing techniques such as Lidar and radar for obtaining point cloud data – even from reflective surfaces such as metal or glass and uniform textures like snow, white surfaces or ice – the opportunities...

Which Photogrammetry Solutions Are Surveyors Waiting For?

Exploring the Demands of Geoprofessionals
Photogrammetry is a well-established technique for acquiring dense 3D geospatial information. In fact, the method is as old as modern photography, dating back to the mid-19th century. The science has continued to evolve over time, of course, and – especially in view of the recent advancements in computer vision and machine learning – the technology is no longer as simple as it may seem. Developers of photogrammetric equipment and software face the challenge of providing the mapping and surveying community with solutions that are sophisticated, yet also meet high customer expectations in terms of user-friendliness. At 'GIM International', we conducted... (read more)

Recent Developments in Close-range Photogrammetry

A Measurement Technology in Transition
Dramatic advances in automatic digital image analysis have opened up new applications and made photogrammetry applicable for a broader field of users that lack specific knowledge of photogrammetry. Megatrends such as Industry 4.0, building information modelling (BIM) and the digital transformation are driving the advancement of 3D measurement technologies, both in terms of high-end systems and low-cost sensors. New technical challenges such as autonomous driving or unmanned aerial vehicles are demanding innovative sensor systems, but also extended maps and models of the environment. Modern approaches such as structure from motion (SfM), simultaneous localization and mapping (SLAM) or visual odometry are... (read more)

Catching up on Photogrammetry and Laser Scanning

An Impression of the Oldenburger 3D-Tage Event
In the German geospatial industry, there is a longstanding platform for open and constructive dialogue with researchers but also informal talks and discussion in between. It is called the Oldenburger 3D-Tage and is held annually at the Jade University of Applied Sciences in the northern German city of Oldenburg. This article provides a round-up of the 18th edition of the event which took place in February this year and offered delegates an inspiring update on the latest developments in all aspects of 3D mapping, both photogrammetry and laser scanning. The 3D-Tage programme is pretty straightforward: two full days of sessions... (read more)

Aerial Triangulation Module for Photogrammetry Suite

SimActive, the Canadian developer of photogrammetry software, has announced the introduction of aerial triangulation (AT) as part of its Correlator3D photogrammetry suite. SimActive’s AT is an automated process based on unique algorithms for tie point extraction and advanced minimisation techniques for bundle adjustment. Leveraging the GPU and multi-core CPUs, rapid AT is possible allowing entire projects to be processed within minutes. SimActive designed the module to achieve the highest productivity with the capability of processing even the most demanding of projects, such as those from UAV platforms using consumer grade cameras with only GPS information. Through intense research and development,... (read more)

Photogrammetry Tool for UAV Land Surveying Missions

Before the introduction of small unmanned aerial vehicles (UAVs) for aerial photogrammetry, planes, helicopters and metric cameras were used. Aerial mapping projects were often not only costly, but also complex due to the images being taken from high altitudes. UAVs have provided more affordable and faster aerial mapping solutions. When it comes to planning survey missions for small UAVs, UgCS is suitable software for the job. It supports most UAV platforms and provides useful tools such as a photogrammetry tool and an image geotagging tool. The photogrammetry tool in UgCS (designed by SPH Engineering) allows creating and flying photogrammetry missions... (read more)
