Optoelectronic multiple plane sensor and method for detecting objects

摘要

The sensor (10) has image sensors (16) for receiving a pixel image of a monitoring area using a set of light receiving units, and a controller for detecting an object from the image data of the pixel image. Each of the image sensors has a pixel row with the receiving units, where the image sensors are arranged at a distance from each other, such that each image sensor covers a plane (20) of the monitoring area. The controller outputs a warning signal or a switching signal to a machine in the monitoring area, when a protected zone is hurt or a hazard is detected. An independent claim is also included for a method for detecting an object in a three dimensional monitoring area.
