Detecting and recognizing objects from 3D meshes


After installing these packages, let's start the detection. What are the procedures involved? Here are the main steps:

  1. Building a CAD model of the object or capturing its 3D model

  2. Training the model

  3. Detecting the object using the trained model

The first step in the recognition process is building the 3D model of the desired object. We can do it using a CAD tool, or we can capture the real object using depth-sensing cameras. If the object is rigid, then the best procedure is CAD modelling, because it will have all the 3D information regarding the object. When we try to capture and build a 3D model, it may have errors and the mesh may not be look like the actual object because of the accumulation of errors in each stage. After building the object model, it will be uploaded to the object database. The next phase is the training of the uploaded object on the database. After training, we can start the detection process. The detection process will start...
