Components of the visual system of the fully automatic visual selection machine (1)

   The visual system of the fully automatic visual selection machine is its core component, responsible for capturing, processing, and analyzing the image information of the target object, thereby achieving automated selection and classification. The visual system typically consists of the following key components:

1. Industrial Camera (Camera)

   Function: Used to capture images of objects to be selected.

   Type: Area Camera: Suitable for static or low-speed moving objects.

   Linear array camera: suitable for high-speed moving objects (such as products on conveyor belts).

   Resolution: High resolution cameras can capture clearer images and are suitable for detecting small defects or details.

   Frame rate: High frame rate cameras are suitable for high-speed production lines to ensure that images are not blurry.

2. Light source

   Function: Provide stable lighting, ensure clear and high contrast images, and facilitate subsequent image processing.

   Type: LED light source: commonly used type, with long lifespan and stable brightness.

   Circular light source: used for uniform illumination.

   Backlight source: used to detect the contour or edge of objects.

   Coaxial light source: used for detecting highly reflective surfaces.

   Lighting methods: forward lighting, backward lighting, lateral lighting, etc., selected according to the characteristics of the object.

3. Lens

   Function: Image the object onto the camera sensor.

   Parameter: Focal length: determines the field of view and working distance.

   Aperture: controls the amount of light entering, affecting image brightness and depth of field.

   Magnification: Used for detecting small objects.

   Types: Fixed focus lens, zoom lens, telephoto lens (used to reduce perspective errors).
