Abstract
In order to detect flying objects, a camera configuration is used for video monitoring of a monitoring space, and a control unit is used for controlling the camera configuration and evaluating the video frames recorded by the camera configuration. The camera configuration has an infrared illuminator for the monitoring space and at least one camera with an infrared image sensor. The infrared illuminator is preferably operated in a pulsed fashion synchronously with a measurement cycle of the camera.
Claims17
A device for detecting objects, the device comprising:
- a camera configuration for video monitoring a monitoring space, said camera configuration having an infrared illuminator emitting infrared radiation into the monitoring space and at least one camera with an infrared image sensor;
- and
- a controller for controlling said camera configuration and evaluating video frames recorded by said camera configuration, said controller configured to operate said infrared illuminator in a pulsed fashion, and a timing of said infrared illuminator being synchronous with a measurement cycle of said at least one camera, wherein said controller is configured to operate said infrared illuminator with infrared pulses of different radiation power, and to determine a distance of an object from said camera configuration and/or a movement of the object from an intensity difference of measurement signals recorded by said at least one camera as a result of the infrared pulses of different radiation powers.
A method for detecting objects, which comprises the steps of:
- recording video frames of a monitoring space by a camera configuration and evaluated by a controller;
- irradiating the monitoring space by means of an infrared illuminator and the video frames of the monitoring space are acquired by means of at least one camera with an infrared image sensor;
- operating the infrared illuminator in a pulsed fashion synchronously with a measurement cycle of the at least one camera;
- operating the infrared illuminator with infrared pulses of different radiation power;
- and
- determining a distance of an object from the camera configuration and/or a movement of the object from an intensity difference of measurement signals recorded by the at least one camera as a result of the infrared pulses of different radiation powers.
