1.3.3 3D Recognition Camera Placement

3D recognition system is one of the famous applications that being develops that able to reconstruct the object structure architecturally through the images from several cameras with different orientation and position. According to Takahashi et al., 2006, the two main point should be considered as important that may cause performance degradation in determining the 3D recognition of object; 1 quality degradation of input images depending on capturing device and conditions; 2 capturing viewpoint not suitable for distinguishing the object. By using two cameras that placed according to the suitable orientation and position calculate using the evaluation function based on universal eigenspace that captured main architecturally of the object. The effectiveness of this method shows a great increment in recognition rate almost 50 from the previous method in low resolution of image tested in the research. Not only that, in industrial application, there is a lot of machine vision used in industrial application in providing a better supervision features that helps in monitoring process in a system. The introduction of machine vision helps a lot in finding the replacement of human vision in industry. Karabegovic et al., 2006 proposed a various type of machine vision with single and multiple cameras according to the needs of the process requirements. This research mostly on application of 3D vision in industrial robot working process that describes the position and orientation of the camera used in industrial such as depalletizing crankshafts that using 2D robot vision, depalletizing motor blocks using 2 1 2 D robot vision and 3D stereo vision using one, two and eight cameras. The implementation of this robot vision system used in various applications present the better solution in replacing human vision. 16 3D recognition system acts as the backbone of the inspection system where it provides various data in x, y and z coordinates. The position and rotation depends to the requirement of the system that fits to their task but the mathematical approach need to be specified equally to the camera placement. This will help to generate new equation in findings x, y and z coordinates. Several of 3D inspection system applied in industry as described by using multiple cameras with different position and angle according to the task requirement. It seems as a great vision sensor where the entire object can be analyzed throughout the system.
