Structured Light Scanner Vs Photogrammetry

Texture might disturb detection of the light pattern making it more difficult for the scanner to work.

Structured light scanner vs photogrammetry.

Hi all i m interested in 3d scanning for digital media production and am curious what you all think the best approach is in terms of hardware. Some 3d scanners can also collect the texture color of the objects in addition to the shape. Digital photogrammetry white light structured scanning and lidar a term which depending on who you ask is either a. 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.

In all cases the computer tries to understand what it s seeing. 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. 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. A 3d scanner works better with objects with little texture as it relies on recognizing its projected pattern.

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. 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. 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. Like working with a blindfold another great advantage of using a 3d scanner is to see what you are doing in real time.

Applications for structured light 3d scanning. The target scanning area will be 7 ft by 4ft. Currently looking at the david sls 3 scanner.
