Hi Rango986, weight defines the influence of a point in calculations. RealityCapture uses natural features and control points together. In general, there are much more natural features than user-defined control points. If some of these points are matched incorrectly, then it is difficult to align images correctly. The weight is one way of saying “use this point and drop all natural points which do not agree”. On the other hand, increasing the point weight will make the alignment sensitive to errors in positioning of the point in the image. Even with the best efforts, it is difficult for a human to place a point with a precision of under 3-4 pixels, while natural points are placed with sub-pixel accuracy. However, it is recommended to leave the default weight value.
By changing this value you are setting the higher priority to that point. If the value is higher, the position is taken as more serious for the application. The changing of weight is recommended, where you are sure that the point is on that place and you want to use it in the alignment. If CP is floating around the structure, it is not good and it should be placed more preciously or not used at all.
