How do 3D Scanners Work?
If we look at most applications of the technology, 3D Scanners can be broadly classified into two main types :
- Optical 3D Scanner
- Laser 3D Scanner
Optical 3D Scanner
Optical scanners can capture 3D data by analyzing the interaction of light with an object. They work through various methods, including projecting patterns, capturing stereo images, and using structured light, each offering unique advantages and disadvantages.Optical 3D Scanners use the following methods to capture the data they are studying :
- Pattern Light Projection Method
- Stereo Camera Method
- Structured Light Method
These methods of scanning have their own advantages and disadvantages and you may want to consider the factors that apply to your circumstances before investing in a 3D Scanner of your own! Let us take a look at the workings of some of these optical 3D scanners.
Pattern Light Projection Method
Works by projecting patterns of light onto the object and analyzing the deformation.Advantages: Fast, accurate, good for large areas.
Disadvantages: Sensitive to ambient light, may not work well on reflective surfaces.
Applications: Reverse engineering, inspection, quality control, 3D printing, cultural heritage preservation.
Stereo Camera Method:
Using two cameras to capture images from different angles and triangulating the object’s surface.Advantages: Affordable, simple to use.
Disadvantages: Less accurate than other methods, limited range.
Applications: 3D modeling, photogrammetry, robotics, augmented reality.
Structured Light Method
This method is similar to pattern light projection, but also uses a structured pattern (e.g., stripes) for more accurate analysis.Advantages: High accuracy, good for textured surfaces.
Disadvantages: Can be computationally expensive, slower than other methods.
Applications: Medical imaging, dentistry, facial scanning, 3D printing, product design.
These are the main methods of operation for optical 3D scanners. Optical 3D scanners offer a plethora of advantages when it comes to quickly analyzing various objects shapes and even pattern recognition when being combined with AI.
Laser 3D Scanner
Now, let us take a look at some of the methods of operation for laser scanners. Unlike Optical scanners, laser scanners are mainly used to measure the distance to various objects. They operate using various triangulation methods each offering distinct and unique data to provide insights and understanding. These laser scanners are known for their high accuracy and long range, making them ideal for large-scale projects like surveying, construction, archeology and even astronomy. Let us take a deeper look at some of these methods of operation and try to understand them better.Laser 3D Scanners use the following methods to capture the data they are studying :
- Time of Flight (ToF) Method
- Triangulation Method
Both of these methods have their own strengths and weaknesses. depending on the nature of your operation, you may want to consider the pros and cons of each method and decide for yourself which type of Laser 3D Scanner would be best for you. Now, let us take a look at some of the applications and benefits of these methods.
Time of Flight (ToF) Method:
It works by measuring the time it takes for a laser pulse to travel to the object and back.Advantages: Very fast, long range.
Disadvantages: Can be expensive, less accurate than other methods.
Applications: Surveying, construction, archaeology, architecture, forestry,astronomy, etc
Triangulation Method:
This method works by measuring the angle between a laser source, the object, and a camera to determine the object’s surface.Advantages: High accuracy, good for small objects.
Disadvantages: Slower than ToF method, limited range.
Applications: Reverse engineering, product design, quality control, 3D printing, medical imaging.
Since laser scanners are more expensive and a little slower than some Optical scanners, they do not see widespread use out of certain specific niche situations. However, that being said these scanners can be quite versatile and often the data collected to the use of these scanners have led to some of the biggest discoveries of mankind.
