As I've been doing some research into 3D reconstruction (modeling of physical 3D objects), I've encountered many solutions. I'm curious what are some effective ways for reconstructing 3D objects. For example:
It depends on the accuracy you want to achieve and the information you need. If you're okay with few cm accuracy and no real rgb data go for the lidar.
Photogrammetry from a collection of images is usually on the scale of ppm when it comes to accuracy. But to achieve this accuracy you'll have to go through post processing and use special cameras.
OpenCV is the low cost version of photogrammetry. You have fast but not very accurate algorithmy for every-day cameras.
So it's all about money/time you have and the geometric/radiometric accuracy you want to achieve.
