![]() You can get real distances directly on the picture. Once you have made the rectification, Plumb-Bob knows the parameters needed to know to convert every point on the image in real world coordinates. ![]() The algorithm can use correction parameters, for a large number of lenses, from the Lensfun database (), which is included in the software.Īs result you get a rectified image you can use as template in your CAD application, in order to retrace the drawing. A Complete History of the Plumb Bob and How to Use It 1. How To Use A Plumb Bob Around The Home 63.2K subscribers Subscribe 1K 114K views 4 years ago A simple video on how to use a plumb bob Amazon Link: Shop. Plumb-Bob provides also a tool for correcting lens distortion (an aberration that causes straight lines to curve). Specifically designed for unique applications like elevator shafts. The more distant the points are and the less will be the margin of error. Our precision machined brass plumb bobs are made in the USA to our specifications. These points have to lay on the same plan we want to survey and they have not to be on the same line (not collinear). The real coordinates of the 4 key points. Plumb-Bob is a perspective rectifier useful in many fields: architectural survey, building renovation, furnishing design, estate agents, and it represents a real completion for the metric / photographic survey.Ī picture not too big (2 MegaPixels are enough), where 4 known key points are clearly visible. It is sufficent to know 4 key points of the plan to rectify. A plumb bob is simply a weighted material with a central point that is suspended and gives a precise vertical location. ![]() With Plumb-Bob you are able to transform an usual picture in a plan view. ![]()
