4D vision sensors for object recognition and inspection are advanced industrial devices used in automation and quality control. These sensors are typically developed by companies specializing in industrial automation, such as Keyence (Japan), Cognex (USA), or Sick AG (Germany). They serve industries like manufacturing, logistics, and automotive by providing high-precision 3D imaging and time-based (4D) analysis for detecting object dimensions, defects, or positioning. Products include smart cameras, laser scanners, and depth-sensing systems, enabling real-time inspection and robotic guidance. These solutions enhance efficiency and accuracy in production lines.
