Le tecniche di acquisizione delle immagini 2D/3D. 2D/3D acquisition techniques provide information on the position and size of objects. In fact, the images acquired by the sensors in the visible field provide information on the aspect but are "flat", ie they do not provide information on the distance at which the objects are. In human vision this problem is solved with the interaction between the two eyes through the technique of stereoscopy. This principle is the basis of one of the 3d techniques of computer vision. There are other techniques such as laser ranging, grid-based, time-of-flight, and photogrammetry. Le tecniche di acquisizione 2D/3D forniscono informazioni sulla posizione e sulle dimensioni degli oggetti. Infatti le immagini acquisite dai sensori nel campo del visibile forniscono informazioni sull'aspetto ma sono “piatte”, ossia non forniscono informazioni sulla distanza a cui gli oggetti sono. Nella visione umana questo problema è risolto con l'interazi...

{Lo stadio di acquisizione delle immagini di un sistema di visione artificiale}   #ArtificialVision, #ComputerVision, #FrameGrabber, #ImageAcquisition, #ImageProcessing, #ImageSensor, #Imaging, #Lighting, #MachineVision, #Optics Generally the acquisition unit of an artificial vision system, commonly synthetically identified also with the term of "imaging unit", is basically composed of an illumination device, an optical assembly, a camera and an electronic acquisition board, commonly called "frame grabber” and mounted within an electronic computer. The illumination device task is to lighting the object of interest with a specific and controlled light radiation. The optical assembly provides the adequate visual coupling between the camera and the object of interest, so that the object is completely framed (field of view) and has the correct contrast and optical focusing conditions. The camera contains the electronic sensor able to capture the light radiations tha...

{La Visione Artificial} #ArtificialVision, #ComputerVision, #FrameGrabber, #ImageAcquisition, #ImageProcessing, #ImageSensor, #Imaging, #Lighting, #MachineVision, #Optics Artificial vision consists of a series of processes that aims to generate an approximate model of the three-dimensional (3D ) real world starting from single or multiple bi-dimensional (2D) images. The principal aim of the artificial vision is that to reproduce the human vision. By vision we mean not only the acquisition of a two-dimensional photograph of an area of interest, but above all the interpretation of what is contained in that area. An artificial vision system is an equipment able to acquire images from real world and to elaborate them in order to obtain useful information for our purposes. It generally is composed by: an acquisition unit, a storage unit, a processing unit and a visualizzazione unit. {La Visione Artificiale consiste in una serie dei processi che mirano a creare ...

#ArtificialVision, #ComputerVision, #FrameGrabber, #ImageAcquisition, #ImageProcessing, #ImageSensor, #Imaging, #Lighting, #MachineVision, #Optics 17/11/2019.  Science has always tried to artificially reproduce the five human senses, and in particular that between them that produces the greatest amount of information, namely the vision. Typically an artificial vision system is mainly composed of a sensory part which is made up of an image acquisition unit. Generally, downstream of the acquisition unit there is a data storage unit and a unit for processing them. The processing unit elaborates images in order to make sense to them and to extract from them information that are useful for the purpose for which was decided to undertake the artificial vision study. The last stage of an artificial vision system is composed generally from a user interface that has the task of communicating the results of the entire process outside the system. Partic...
