  Industrial cameras are the most important component in machine vision. It is widely used in many fields. For example, industrial fields, sports projects, packaging and labeling fields, scientific research, military science, aerospace, intelligent transportation, hospital schools, factories and mines, cultural relics appraisal units, criminal investigation and justice, etc. In addition, industrial cameras also have a lot of technical terms. Let's take a look at the industry camera manufacturer in Shenzhen, TEO.

  What are the technical terms for industrial cameras?

工业相机

  Imaging plane (focal plane): generally refers to the plane in which the imaging material is located. Light is concentrated on the imaging plane through the lens to form a clear picture.

  Focal length: refers to the distance of the lens from the film. If the focal length is appropriate, the light reflected by the scene can be concentrated on the imaging plane through the lens, becoming a point, and if the focal length is not suitable, it becomes a circle, which causes the photo to become imaginary.

  Exposure: When the shutter is open, light passes through the lens, passes through the aperture, enters the darkroom, and finally shines on the imaging material. This process is called exposure.

  Exposure: The amount of exposure is the amount of light in an exposure. If the exposure is too low, the color of the photo will be dark. If the exposure is too high, the color of the photo will be white. If it is too low or too high, the details in the photo will be lost. The amount of exposure is usually determined by the combination of the aperture value and the shutter speed.

  Aperture value: refers to the size of the darkroom window. The lower the aperture value, the larger the window, the more light is transmitted, which increases the exposure, and vice versa.

  Shutter speed: refers to the time when the shutter is open. If the shutter speed is slower, the longer the opening time, the more light penetrates, causing the exposure to increase, and vice versa. If the subject is a moving object, a faster shutter speed is required.

  Depth of field: refers to the front and back distances that can be clearly displayed in the photo. In the landscape photo, the depth of field is required, and the smaller focal length can obtain a larger depth of field.

  Zoom: The zoom of a digital camera is divided into optical and digital. Optical zoom is a zoom in and out of the subject that needs to be captured by lens movement; digital zoom simply crops the image captured by the CCD.

  Aperture priority: refers to the photographer manually specifying an aperture value, the camera automatically calculates the exposure mode corresponding to the shutter speed according to the metering result, suitable for scenes that need to control the depth of field

  Shutter priority: refers to the photographer manually specifying a shutter speed, the camera automatically calculates the exposure mode corresponding to the aperture value according to the metering result, suitable for shooting scenes of fast moving objects.

  The above is the terminology of industrial cameras introduced by TEO. In fact, in addition to the above terms, industrial cameras can be divided into many types according to the type. For example, according to the chip can be divided into ccd industrial camera, cmos industrial camera. According to the structural characteristics of the sensor, it can be divided into a line camera, an area array camera and the like. And the demand for industrial cameras varies from company to industry. Therefore, before purchasing an industrial camera, you must find a professional manufacturer to understand and then make a decision
