Obtaining Three Dimensional Point Clouds from the Digital Images of Rectangular Prism Shaped Objects

Öz

The processes applied on the pixels by the image processing methods provide us information about images. Image processing is a computer programming area which can be used in computer integrated industrial applications and it is one of the research areas of reverse engineering. In this study, a new system in which color digital images are interpreted by using image processing method was developed. The purpose of this study is to improve a system to interpret the images, which are taken with a hand camcorder or digital camera, and to obtain point clouds by evaluating with image processing and to convert these point clouds surface or solid model in a computer aided design program. In accordance with these purposes, the three dimensional point clouds are obtained from a rectangular prism shaped object in the specified area. These point clouds can easily be converted into three dimensional solid or surface models in a Computer Aided Design (CAD) program. In this reverse engineering study, the developed system is explained and sample parts are given

• 
• As the number of points in point clouds which are obtained for the object is too much,
• approximately 1-4 million, in the marked image to obtain its solid model needs some time,
• In image processing which is done pixel to pixel according to the color analysis, color loss in the
• image cause regional point loss, which causes some problems to model the part,
• If the size of the object in the image and processed image is big, the size of the obtained point
• cloud file becomes big.
• It is aimed to obtain three dimensional point clouds for circular, curved and complex forms of objects in further studies.
