Structured Light Scanner Vs Photogrammetry

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.

Structured light scanner vs photogrammetry.

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. In all cases the computer tries to understand what it s seeing. 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.

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. 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. Both 3d scanning hardware and photogrammetry based software solutions rely on computer vision of some kind. Like working with a blindfold another great advantage of using a 3d scanner is to see what you are doing in real time.

Among the advantages we find that they are designed to require little or no. A 3d scanner works better with objects with little texture as it relies on recognizing its projected pattern. Texture might disturb detection of the light pattern making it more difficult for the scanner to work. Digital photogrammetry white light structured scanning and lidar a term which depending on who you ask is either a.

The target scanning area will be 7 ft by 4ft. 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. Applications for structured light 3d scanning.
