The next development in 3D Inspection

The Technology

We are XTURA, leaders in industrial photogrammetry. Our groundbreaking technology captures and calculates the precise surface geometry of an object from a set of ordered or unordered images. 

The principles of photogrammetry have been known for many years however, XTURA are the first to have optimised this technique for ultra-high precision 3D capture. This means we generate high density point-clouds for 3D Inspection, but with the accuracy of target based photogrammetry.

Our technology is highly scalable, we have scanned mountains, to vehicles, to fine tooth saw blades and many things in between. We can create bespoke installations entirely tailored to your application and have standard configurations for specific needs.


Central to the principles of photogrammetry is a requirement to match corresponding features in multiple images of a subject, from different viewpoints. Multiple images of the subject must therefore be captured with sufficient overlap to view those corresponding features multiple times. If common feature points are not found or are incorrectly matched, inaccuracy will result. 

Some industrial photogrammetric solutions use targets placed on the subject surface which overcomes this challenge. This approach provides high measurement accuracy, but only captures the ‘targets’, it does not capture any information from the actual subject surface. An additional surface capture technique is required, such as projected light scanning, and these target-based photogrammetry points are used as a high accuracy ‘framework’ onto which surface scan ‘patches’ from the other method can be registered. 

With recent developments in imaging technology (from imaging cameras through to computer vision software) and readily available computational power, more advanced photogrammetry technologies have become available. These can capture and reconstruct full surfaces of objects for 3D inspecton, leveraging the inherent ‘texture’ within the surface of the object as the common features that are viewed. Many more common points are found from highly textured surfaces and are again required to be matched in multiple images to adequately enable 3D reconstruction of the subject’s actual surface and generate a high resolution point cloud. It is not unusual that hundreds or even thousands of images are required for full 3D photogrammetry reconstruction. Clearly the computational resources for 3D reconstruction processing increases (exponentially) with the number of images in the system.

For several years now target-less photogrammetry has been used for capturing highly textured subjects such as rock, soil, corroded metal, wood grain and organic materials as these present the natural random features required to for the computer algorithms to identify unique feature points from which to calculate surface geometry. For this reason, it is a technique used extensively for such applications where visual quality outweighs dimensional accuracy, such as creating 3D assets for computer games and virtual reality applications. This method is also used in applications such as aerial survey, mining and and stockpile measurements, where subject matter displays the high texture needed. The majority, perhaps all, other targetless photogrammetry solutions on the market today are optimised for these applications. 

As might be expected, subjects with low inherent levels of texture, such as painted, coated, machined or molded surfaces present a much greater challenge for existing photogrammetric solutions. For this reason targetless photogrammetry has not broadly been adopted for use within industrial, engineering or production environments... until now!

Through its extensive research into the area, XTURA has now developed a next-generation level capability to fully capture and reconstruct the 3D surfaces of engineered materials with the same high precision previously only found in target-based photogrammetry or more traditional projected light scanning.

The XTURA team will take you through a process to first understand your application needs and then design the GigaScan™ powered solution to meet the requirements. We blend the GigaScan™ technology with any further required physical infrastructure (frameworks, fixtures, rigs, robotics etc), plus any further analysis software, to become the end-to-end solution.
