Capturing BIM Data: An Affordable Alternative to Laser Scanning

Posted on Tuesday, November 7th, 2017

BIM and the Importance of Image Processing BIM is the process of designing a building collaboratively with just one coherent system of 3D computer models, rather than multiple sets of separate diagrams. This leads to huge savings in time and resources, more accurate estimation, and fewer mistakes and alterations due to loss of data. BIM data can then be used for on-going management and maintenance of the building. The field of construction design has been transformed by the rise of digital technology. First, hand-drawn blueprints were replaced by 2D CAD systems. Then, as computing power grew, this evolved into 3D CAD. BIM is the next stage in the computerization of construction design, allowing more complex projects to be undertaken than…Read More

Posted on Monday, October 30th, 2017

Instructional tutorial videos are a great way to learn PhotoModeler.  We’ve recently done a few updates to the PhotoModeler tutorials: A new forensics single camera tutorial Some new voice overs Key videos on YouTube Newest Tutorial Video for Forensics We recently published a new tutorial that will be of interest to those doing forensic measurement from single images (esp. those taken by security cameras and dash-cams). A recent release of PhotoModeler added an improved way to compensate for lens distortion for the highest accuracy results – this video describes this process. This tutorial describes how to extract important measurements like heights and positions in a crime scene from a security or surveillance camera image.

Forensic Photogrammetry: A Case Study

Posted on Monday, October 16th, 2017

Forensic Playground photo repaired

This is a guest article by forensic imaging consultant Michael Mayda. Michael is an expert witness specializing in photogrammetry and visibility analysis. He has been in business since 1977, and currently lives in Sacramento, California.   Why Use Photogrammetry in Forensics? Photogrammetry can be a very powerful tool in forensic analysis. It is often useful to have an accurate 3D reconstruction of an accident or crime scene, especially in cases where position, distance and perspective are important. Given the large number of photos taken at these scenes, photogrammetry can be a practical way for investigators, lawyers, and insurance adjusters to obtain better information. In addition, photogrammetry can be used to preserve or recover measurement data long after the on-scene investigation…Read More

How to Digitize Templates and Patterns With a Camera

Posted on Thursday, August 3rd, 2017

In a number of industries measurements are made of objects and equipment in the field, and then materials are manufactured to fit those existing objects. Some common industries like this are kitchen counter tops, boat covers, enclosures, or flooring, wall cladding, and stairway coverings or lifts. A common approach within these industries is to create a template on-site from paper, cardboard, or plastic to form the fit of the final materials. The templates are returned to the manufacturer, and are used to form or cut the material (such as a kitchen marble counter top, or a boat cover), and the finish product returned to the customer or site for installation.  Accuracy of the cut and formed materials is key to…Read More


With a Camera Measure, Monitor, and Document Bridges

Posted on Monday, July 31st, 2017

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 costly endeavor to measure them all. Photogrammetry allows professionals to obtain accurate three-dimensional descriptions of structures from photographs. As compared to traditional measurement methods, this technique produces more accurate results, and it is suitable for various civil engineering projects. Furthermore, the method is less expensive than most traditional techniques. It is a standard practice for professionals to conduct feasibility studies before restoring a transportation structure.…Read More

With a Camera and a Drone Audit a Mine Reclamation

Posted on Monday, July 10th, 2017

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 by the company or by an agency, may be aided with aerial photography and 3D surface modeling. The topography of most mining sites makes it difficult for field experts to collect data needed for site mapping. Climbing one quarry face after another to take measurements using GPS systems or other survey tools is a labor-intensive, time-consuming, and dangerous activity. Use of unmanned aircraft systems (UAS)…Read More


With a Camera Perform Non-Contact Industrial Measurement

Posted on Tuesday, June 27th, 2017

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 in good time and at reasonable cost. Traditionally we have thought about photogrammetry as being from the air – how most of our maps are created. Aerial photogrammetry entails using photographic images captured from airborne platforms while terrestrial photogrammetry utilizes photographs captured from the ground. In addition, close-range photogrammetry refers to a process where the camera is ‘close’ to the object being measured. Industrial uses…Read More
