A weighted motion detection registration method is used to calculate the difference between the current image frame and the previous image frame. The primary steps involved are Motion, Edge detection and image segmentation, Depth estimation and Shift algorithm. This research study focuses on particular conversion method recommended that facilitates various image processing algorithms to improve the conversion of 2D images to 3D images. Image-based 3D-modeling techniques for creating a 3D representation of a scene from one or more 2D images have received great attention and methods to improve the conversion process have been probed by both academicians and researchers. And if you get stuck, you can always check out our numerous CAD tutorials or ask questions in the Onshape Forums.Abstract-The advent of modern 3D technological devices and the desire to create 3D images from the numerous 2D images have increased tremendously. Alternatively, there are many bureaus that offer 2D-to-3D model conversion, but it can be costly – and again, you may pay to have some models created that you may never use.Īnother advantage of converting old 2D drawings, especially those that you are very familiar with, is that it’s a great way to learn 3D modeling. Otherwise, you should wait until you need them so that you don’t waste time remodeling parts that you may never use again. If you have a common set of 2D parts that you use regularly, then you should convert them now.
For more complex parts, you could use this technique to get you started or get you 20-to-80% there, before having to make a few final additions to complete your design. If you have a lot of prismatic parts to convert, you can apply this technique yourself.
In the video above, I have taken a basic 2D drawing and converted it to 3D in a few simple steps in Onshape. It’s definitely a worthwhile exercise to recreate your most frequently used 2D drawings in 3D, so you can reuse them, check that they fit correctly, make modifications quickly and calculate accurate assembly mass properties – not to mention many other beneficial uses. Most of these may be obsolete, from products you stopped making years ago, but some may still be relevant today and you may want to reuse them in your 3D designs. If you started your design career on a 2D CAD platform, then chances are you have hundreds (if not thousands) of DWG files.
