Structured Light Scanner Vs Photogrammetry

Some 3d scanners can also collect the texture color of the objects in addition to the shape.

Structured light scanner vs photogrammetry.

They either project visible or invisible light onto an object and capture the result with a camera or they use software algorithms to estimate depth from images. The target scanning area will be 7 ft by 4ft. Like working with a blindfold another great advantage of using a 3d scanner is to see what you are doing in real time. Texture might disturb detection of the light pattern making it more difficult for the scanner to work.

Currently looking at the david sls 3 scanner. 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. A 3d scanner works better with objects with little texture as it relies on recognizing its projected pattern. 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.

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. Among the advantages we find that they are designed to require little or no. Digital photogrammetry white light structured scanning and lidar a term which depending on who you ask is either a. In all cases the computer tries to understand what it s seeing.

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. 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. Applications for structured light 3d scanning.
