3D Photogrammetry & Modeling

3D Photogrammetry & Modeling takes a series of photos of the object under investigation and builds an accurate 3D model which can be measured and further analyzed.

Photogrammetry is the technique of taking multiple overlapping photographs and deriving measurements from them to create 3D models of objects or scenes. The basic principle is quite similar to the way many cameras these days allow you to create a panorama by stitching together overlapping photographs into a 2D mosaic.

Photogrammetry is a type of photography that is used to create 3D objects or environments from photographs. In this process, a light source is usually used to project an image on a surface in order to create an accurate representation of the object.

Photogrammetry has existed for quite some time, but the technology has been adopted in the last decade due to recent advancements in digital cameras and software.In photogrammetry, one typically uses multiple photos taken from different angles in order to generate a detailed 3D model of an object or environment. As these photos are traced by grid coordinates on the model, they allow for more accuracy and detail than traditional methods such as using cameras or laser scanners to map out an object’s shape.

Photogrammetry is used for creating 3D models by taking photographs and then processing them into 3D models using computer software. The process involves measuring one or more points on an object by using photographs taken from different angles to create a 3D model with as much detail as possible.

Advantages of Photogrammetry

Accurate records – Photogrammetry can produce an actual, permanent photographic record of a particular location or object when capturing an image. As the image has metric properties, it is also a highly accurate, measured record that can be relied on for a variety of projects.

Ease, speed and affordability – it is a much easier, faster, and cheaper way of obtaining measurements and other information than traditional methods. It requires minimal fieldwork, and photogrammetry images can also be used repeatedly for multiple analyses.

3D scanning – Photogrammetry is a useful 3D scanning technique for both small and large objects. It can be used to capture buildings and landscapes which would be impossible to scan otherwise. As photogrammetry software can automatically create 3D models from images, it also provides an easier, cheaper way of scanning than other methods.

Access difficult locations – Aerial photogrammetry can be used to survey locations that are difficult or dangerous to access, limiting the risk to crews while maintaining high levels of accuracy.

Less disruption – it can be used to survey areas, such as roads and cities, with minimal disruption, allowing analysis to be done from the office rather than on the ground.

Simple analysis – the coordinates of each point in the mapping field can be evaluated with minimal effort and cost. Full color models and point clouds are easy to visualize and analyze, which is ideal for presenting information to the public, state, or organizations.

Disadvantages of Photogrammetry

While there are plenty of benefits to using photogrammetry, it isn’t a flawless technique. Here are the limitations of photogrammetry.

Affected by weather – One of the main disadvantages of photogrammetry is that it’s susceptible to poor weather conditions. Rain, fog and wind can affect image quality, while dense vegetation can also obscure the camera’s line of sight.

Environmental restrictions – Terrain and the nature of built environments can restrict the altitude of flight needed to achieve high accuracy and image resolution.

Difficulty of matching points – With low contrast or uniformly textured surfaces, such as sand, water bodies and short grass, it can be difficult to march points between images.

How much does 3D scanning cost?

The basic pricing for medium objects like this with minimal processing starts from $800 and can go up to $1200.
