enjoylife / simple_triangulation.cc

Created June 9, 2020 04:59 — forked from cashiwamochi/simple_triangulation.cc

This code is used for simple triangulation. It uses findEssentialMat, recoverPose, triangulatePoints in OpenCV. For viewer, PCL is used. You can watch 3D points and 2 camera poses. I checked alcatraz2.jpg and alcatraz1.jpg in pcv_data.zip (https://www.oreilly.co.jp/pub/9784873116075/). Perhaps there is something wrong ( actually it looks working…
