The process of monitoring the health of bridges demands reliable measurement techniques. Traditional methods of monitoring the conditions of bridges are disruptive and may cause inconvenience to users. In addition, the approaches are labor-intensive, and the results are usually less accurate. Considering that there are many transportation structures that require routine monitoring, it is a […]
Mining companies are often required to restore mine sites to economically usable conditions after extracting minerals. This process, usually referred to as mine reclamation, involves rehabilitation and other processes that minimize the environmental impact of mining. The reclaimed land can be used for agricultural, recreational, commercial, and residential uses. An audit of the reclaimed site […]
Today’s industries demand accurate and reliable measurements. Sometimes it can be expensive, time consuming or difficult to achieve the required precision using traditional measurement methods. For most design and fabrication processes, the margin of error is small, and inaccurate measurements can result in losses. Photogrammetry enables industries to obtain accurate and reliable measurements from images […]
Unfortunately, this is an all too common story: The convenience store clerk was alone when a man entered the store. He demanded money and cigarettes. When the clerk refused, the clerk was beaten and then shot, leaving no eyewitnesses to this horrific crime. But there was a ‘witness’ – the store had a single security […]
Surveying is an essential process in mapping, mining, construction, and architecture. This time and labor intensive process involves using a wide range of traditional and modern equipment to obtain measurements. Depending on the nature of the task, the required accuracy, and the challenges involved, a surveyor can use a tape measure/roller, a total station, a […]
With A Camera Blog Series In our second of the series we describe a unique and interesting application of measuring fabrics, sails, and flexible structures – something that is very hard to do with other methods. Introduction Flexible structures, such as sails, fabrics, flexible wings, and solar sails are very hard to measure […]
A New Blog Series We introduce a new blog series called “With A Camera“. With each blog post in this new series we describe an application of close range photogrammetry – that is, 3D measurement and modeling with a camera. The articles will describe significant real-world problems and how photogrammetry was able to uniquely solve […]
To get high accuracy with a drone photo-based survey, one usually needs to place and survey ground control points. Ground control points are either man-made targets (e.g. large cross) that you place on the ground before the flight, or visible natural features, surveyed with a high accuracy instrument (total station or RTK GPS). To achieve […]
When two or more cameras, affixed in un-moving positions, are used in a project, the images taken by these cameras can be replaced in the project without having to re-orient them. Doing this can save time and effort for project setups or camera rigs that are reused repeatedly. This procedure of swapping images on fixed […]
Eos Systems is introducing two new community programs: PhotoModeler Ambassadors and PhotoModeler Grants. PhotoModeler Ambassadors A PhotoModeler Ambassador is a keen member of the PhotoModeler community that regularly uses PhotoModeler and photogrammetric processes in their work, and regularly shares information, using various media, about their experiences with colleagues and the community. Ambassadors receive recognition in […]
