These sensors use images captured by a camera to determine the presence, orientation, and accuracy of parts. These sensors differ from image inspection systems in that the camera, light, and controller are contained in a single unit. Which makes the unit’s constructions and operation simple. The differences between these sensors and other general-purpose sensors. Examples of multi point inspections can be done with a single sensor. In addition to the wide field of view, detection is possible even when the target position is not consistent.
The vision sensors which are viewable objects operate in a very similar way as camera objects will render the objects that are in their field of view and trigger detection. If the specified thresholds are over and undershot. Which can detect renderable entities should be used over proximity sensors mainly when color, light, and structure play a role in the detection process. Examples are infrared sensors, light, cameras, etc. Depending on the graphic card the application is running on and the complexity of the scene objects, vision sensors might be a little bit slower than proximity sensors.
- A vision sensor has a fixed resolution. A camera has no specific resolution. It adjusts automatically to the view size.
- A vision sensor image content can be accessed via the application and image processing handles via vision call-back functions.
- These sensors generally require more CPU time and operate slower than cameras.
A camera can display all object types.
