Identify points in the images that can possibly be detected in other images, eg: [[Harris Corner Detection]], [[Edge Detection#Canny Edge Detector]] 3. Search for corresponding points between images, using [[RANSAC]]. Improve using [[Multi-view Stereo#Epipolar Geometry]]. 4. Compute camera positions and 3D point positions such that corresponding viewing rays intersect. 5. Done, 3D object is ready! Can also do surface reconstruction.
