How Easy SLAM is different from Instant Tracking?

Question

Hi ,

I have tried out Easy SLAM example (Unity+Android) from Pro feature. And my observation is as follow:

• It works very well and 3D object is also stable when I point out camera towards surface having rich texture (features)
• It Stuck and perform poorly when the surface is plain white or any other color and 3D object also shaky (Unstable)

My question is, Is Easy SLAM more close to SLAM mapping or Instant Tracking?

Answer 1

Hello,

of course it needs feature points. Plain white/black doesnt have them. Imagine you stay in a perfectly black/dark room. Your eyes will  see nothing except black. Then your brain cannot reconstruct any surface or object. Its the same with slam. If slam sees nothing it cannot reconstruct something. Plain surfaces dont work with camera images. No matter if its easy slam or slam.
