Description

Prefab module smart camera}

The present invention relates to a prefabricated module smart camera, which is a machine vision camera based on deep learning and which can produce an optimal smart camera by combining each module according to the use environment in each module method. will be.

In general, with the development of computer technology, the use of deep learning technology and machine vision functions based thereon is increasing in various fields.

In the field of cameras among various fields, digital cameras are widely used instead of conventional film cameras according to the development of digital technology.

In particular, SLR (Single-lens Reflex) cameras, which were sold at high prices in the past and were known to be used only by professionals, are being sold relatively cheaply and are being supplied digitally.

A DSLR camera, also called an interchangeable lens camera, is an abbreviation for a digital single-lens reflex camera. A single-lens reflex camera.

The DSLR has a mirror that is rotatably formed within a predetermined angle on the optical axis of the lens, so that the light passing through the lens is reflected by the mirror, and the photographer can see through the pentaprism and the view-finder. You can check.

At this time, when a shutter-release signal is input, the mirror is rotated about its axis and raised to depart from the optical axis of the lens, and when the shutter is opened, an image of the subject is formed on the imaging device.

DSLRs are gaining much popularity from users who want to obtain sharper images because they have much better image quality and color compared to general digital cameras.

In general, in the case of a DSLR, it is composed of an interchangeable lens that can be attached to and detached from the camera body (body).

When the interchangeable lens is coupled to the body, power is supplied from the body to the lens, and electrical signals are transmitted and received between the lens and the body.

Like a typical digital camera, the body of a DSLR camera has a shutter-release button, a mode dial for setting the shooting mode, a wide-angle-zoom button or a telephoto-zoom button, and display parts such as function buttons and an LCD window. It has a viewfinder, which is a small window for setting.

However, in the case of a DSLR camera, various interchangeable lenses are attached to the body as needed to capture images. The body of a DSLR camera is not only much heavier than that of a general digital camera, but is also sold at a relatively high price.

Therefore, in order to realize a good image of the DSLR level, there was a problem in that a body as well as an interchangeable lens had to be purchased.

In other words, the use environment of actual manufacturers that require smart cameras is so diverse, and selection of sensors with resolution suitable for each situation, selection of embedded according to difficulty in image processing, etc., determination of interface to transmit output values to the outside, There are many things to consider, such as the selection of wavelength or brightness, selection of magnification and depth of field of the lens.

In addition, the types of smart cameras on the market are extremely limited, and all hardware components constituting smart cameras, including sensors and lights, are fixed.

Therefore, it is not only difficult to select a smart camera suitable for the actual manufacturing environment, but also difficult to change some of the configuration of the smart camera.

In many cases, new development is required as a new model due to these problems, but in reality, it is difficult for the manufacturer to respond to all of them in this case.

Therefore, there is a problem in that small and medium-sized manufacturers can be extremely limited in constructing a smart factory by applying machine vision for production or quality inspection.
