Structured Light Scanning for Capturing 3D Models from Photographs
Structured light scanning has emerged as a cutting-edge technique in the realm of 3D modeling, allowing for the rapid and accurate capture of 3D models from photographs. By leveraging the principles of photogrammetry and structured light projection, this technology enables the creation of highly detailed and precise 3D models from a series of 2D images.
The Working Principle of Structured Light Scanning
Structured light scanning involves the projection of a pattern of light onto the scene being captured, which is then recorded by a camera from multiple angles. The pattern of light is disrupted by the surface texture of the scene, creating a unique set of distortions that can be measured and used to calculate the 3D shape of the scene. This technique is often used in conjunction with photogrammetry, where multiple 2D images are used to create a 3D model.
The structured light pattern helps to improve the accuracy and precision of the photogrammetric calculations, allowing for the creation of highly detailed 3D models.
Advantages and Disadvantages of Structured Light Scanning
Structured light scanning offers several advantages over traditional photogrammetry, including increased accuracy and precision, faster scanning speeds, and the ability to capture complex shapes and textures. However, this technology also has some drawbacks, including the requirement for specialized equipment and expertise, as well as the potential for artifacts and errors in the scanning process.
Examples of Structured Light Scanning Systems
Several structured light scanning systems are available on the market, including the Viper 3S from Steinbichler, the Optotrak Certus from NDI, and the MD7 from MD3. These systems use a range of technologies, including laser projection and high-speed cameras, to capture and process the structured light patterns. They are used in a variety of applications, including architectural modeling, product design, and heritage conservation.

Camera Calibration: Correcting Lens Distortions and Errors
Camera calibration is a process that corrects lens distortions and other errors in photogrammetry. This process involves determining the intrinsic and extrinsic parameters of a camera, which are the parameters that relate the camera’s image points to the actual 3D world points. Camera calibration is typically done using a set of known points, such as corners of a cube or a checkerboard, and the camera’s image points that correspond to these points.
This process helps to correct lens distortions, such as barrel and pincushion distortions, and other errors that can affect the accuracy of photogrammetry.

Accuracy and quality assessment are critical components of 3D modeling from photogrammetry, ensuring that the final product is reliable and meets the intended requirements. By evaluating the accuracy and quality of 3D models created from photographs, users can gauge the effectiveness of the photogrammetry process and make necessary adjustments to improve the outcome.In the realm of photogrammetry, accuracy and quality are measured by various metrics, such as resolution, pixel density, and the consistency of geometric information.
The choice of evaluation method depends on the application and the intended use case for the 3D model. For instance, high-precision applications like engineering and architecture require more stringent accuracy standards than lower-stakes applications like entertainment and art.
Metrics for Assessing 3D Model Accuracy
Accuracy assessment involves evaluating the 3D model against known reference data or measured points to determine the level of precision achieved. Key metrics used for this purpose include:
- Mean Absolute Error (MAE): This measures the average difference between the 3D model’s predicted and actual values, providing insight into the model’s accuracy and precision.
- Root Mean Square Error (RMSE): Similar to MAE, RMSE measures the average difference between predicted and actual values but uses the square root of the averages to account for outliers and extreme values.
