stack, P3 into the stack, so far until the end. This is the Graham scanning method, because we initially selected is from the counter-clockwise direction, so the judgment time correlation, of course we can also choose the clockwise direction, then we are from P12 p11 over there, then we have to determine whether the point in the current stack of two points on the side of the clockwise direction.(4) Then we got the convex hull of these points, and now we are going to do the Delaunay triangle con

models. For the simplest structure of a linear framework, we can use the Viterbi algorithm. If the graph results are tree-shaped, you can use the belief propagation (belief propogation), use the sum-product to get the probability, using max-product to get the optimal configuration. However, these methods are not valid for any purpose. An approximate algorithm, called Loopy-belief propogation, is to infer by faith propagation in non-tree structure, and to get approximate solution by cyclic propa

Orb-slam as Monocular slam, the precision of the frame is determined by the accuracy of the position and posture optimization between frames. So Optimization (optimization) plays a very important role in Orb-slam. This section explores the optimizations used in Orb-slam.Orb-slam chooses G2o as the method of graph optimization, about G2O can refer to http://www.cnblogs.com/gaoxiang12/p/5304272.html.First, why to optimizeBecause the accuracy of camera calibration (cameras calibration) and tracking

Up to now, the most accurate and feasible optical ranging method may be the TOF (time of flight), such as LDM laser ranging, idm infrared ranging and other specific technologies have been achieved in the product, on the other hand, many three-dimensional scanners are now using triangulation method, especially for handheld scanning equipment. However, none of these techniques are suitable for Kinect's household devices: first, the limits of the measure

This topic is the classic convex hull of the optimal triangulation, but this topic may not be convex bag, so to determine in advance whether it is convex, if it is convex bag to continue to split, Dp[i][j] is already in the order of the convex hull on the point i->j is divided into small triangles of the minimum cost, Then dp[i][j] = min (Dp[i][k]+dp[k][j]+cost[i][k]+cost[k][j]), wherein, (J >= i+ 3,i+1Previous diagram from the blog http://blog.csdn.n
