Structured Light Scanner Vs Photogrammetry

3d scanning using structured light has many advantages over photogrammetry which we discussed in this article one of the disadvantages of the structured light is that scanners that use this technology are usually expensive equipment that can cost thousands of euros.

Structured light scanner vs photogrammetry.

Both 3d scanning hardware and photogrammetry based software solutions rely on computer vision of some kind. The target scanning area will be 7 ft by 4ft. Some of the more unusual forms of 3d scanning include computed tomography scans and ground penetrating radar which have fascinating uses in fields like archeology and medicine but this post will cover three specific ones. Like working with a blindfold another great advantage of using a 3d scanner is to see what you are doing in real time.

I would like to possibly combine structured light scanning with photogrammetry in order to improve mesh output in terms of surface detail coverage and texture quality. It seems to me that the options are spend less money but much more time with photogrammetry or sink some cash into a structured light scanner that will do it quicker. Applications for structured light 3d scanning. Texture might disturb detection of the light pattern making it more difficult for the scanner to work.

Some 3d scanners can also collect the texture color of the objects in addition to the shape. Currently looking at the david sls 3 scanner. Among the advantages we find that they are designed to require little or no. In all cases the computer tries to understand what it s seeing.

Like cmms structured light scanners comes in various sizes and can be used on everything from the micro scale such as orthodontics all the way to large volume objects such as airplanes when used in conjunction with retro reflective targets and photogrammetry. Many different 3d scanning technologies exist structured light infrared structured light laser etc and each of them have its own limitations advantages and costs more detail in a next post. A 3d scanner works better with objects with little texture as it relies on recognizing its projected pattern.
