23D vision sensors for object recognition and inspection are advanced industrial tools designed for precision tasks in automation and quality control. These sensors are typically developed by leading technology companies, such as Keyence (Japan), Cognex (USA), or Sick AG (Germany), specializing in machine vision and industrial automation. They serve industries like manufacturing, logistics, and robotics, enabling high-speed 3D imaging, defect detection, and dimensional analysis. Key products include laser-based scanners, stereo vision cameras, and structured light systems, which enhance efficiency in assembly lines, packaging, and inspection processes. These sensors are integral to smart factories and Industry 4.0 applications.
