Param: ORB/WTA_K = "2" [The number of points that produce each element of the oriented BRIEF descriptor. The default value 2 means the BRIEF where we take a random point pair and compare their brightnesses, so we get 0/1 response. Other possible values are 3 and 4. For example, 3 means that we take 3 random points (of course, those point coordinates are random, but they are generated from the pre-defined seed, so each element of BRIEF descriptor is computed deterministically from the pixel rectangle), find point of maximum brightness and output index of the winner (0, 1 or 2). Such output will occupy 2 bits, and therefore it will need a special variant of Hamming distance, denoted as NORM_HAMMING2 (2 bits per bin).

In localization mode, this threshold is used when there are no loop closure constraints with any map in the cache (RGBD/MaxOdomCacheSize). In all cases, the goal is to aggressively loop on a previous map in the database. Only used when RGBD/Enabled is enabled. Set 1 to disable.]

If it succeeds, the proximity links are removed. This assumes that global loop closure and landmark links are more accurate than proximity links.]

If false, the graph is optimized from the oldest node of the current graph (this adds an overhead computation to detect to oldest node of the current graph, but it can be useful to preserve the map referential from the oldest node).

Param: RGBD/OptimizeMaxError = "3.0" [Reject loop closures if optimization error ratio is greater than this value (0=disabled).
