What is Industrial Image Processing?
Industrial Image Processing is the processing and interpretation of images obtained from cameras with computer programs.
The simplest industrial image processing system consists of a camera that provides an image, light systems specially designed for the application, and a computer running the program that automatically processes the digital image and makes the necessary decisions.
The system can perform visual quality control or surveillance operations performed by humans faster and more economically with fewer errors.
Image processing applications can be classified as 2D and 3D.
What is 2D Image Processing?
2D image processing is to analyze an image that is specific with pixel analysis through a filter or a broader color-light analysis. Whenever a change or analysis is made, the image processor has to print those changes so they can appear on the computer screen or make a report on the image itself. If someone takes a picture of a real-life area, then that area will be 3D, but the image will only be 2D. This is because the image has only X and Y axis.
What is 3D Image Processing?
Standard cameras provide images in the X-Y plane. Such systems are called 2D image processing. Technologies that can provide X-Y-Z information, including depth (Z) information to the image, are called 3D image processing technologies. The most widely used 3D technology is the STEROVISION system. This system is a method used to increase the sense of depth and realism by creating two separate images from 2 cameras, just like the human eye. Since the distance and center direction angles are known clearly, the projection of each point on both cameras can be found with simple geometric calculations.
Robotic Machine Feeding Applications with Camera
Such systems are a known flexible solution that can be adapted to all CNC machines. The system consists of two conveyors, 2 or 3D cameras, lighting equipment and an industrial PC with camera software. The shape of the piece is not very important. It is sufficient for the part to be fixed on the conveyor. In 2D solutions, the part must be flat in front of the camera, in 3D systems it is not important as the camera will also control the height.
