Abstract
In a method for recognition of the position of a load on a lifting gear, an active light source and a camera are mounted to a trolley of the lifting gear. Both, the light source and the camera are directed towards the load. The load has attached thereto at least one marker used for the recognition of the load position and including an active light source. In response to incoming light from the light source on the trolley, the light source of the marker transmits a light signal to the camera.
Claims14
A method for recognizing a position of a load on a lifting gear having a trolley for moving the load, comprising the steps of:
- applying to a load at least one marker having a first active light source;
- orienting a camera on the trolley in a direction toward the load;
- sending a first light signal from a second active light source on the trolley in a direction of the marker;
- and
- sending from the first active light source on the marker a second light signal to the camera in response to a recognition of the first light signal.
A device for recognition of a position of a load on a lifting gear having a trolley for moving the load, comprising:
- a first active light source attached to the trolley;
- a camera attached to the trolley, wherein the first active light source and the camera are oriented in a direction of the load;
- a light-sensitive sensor for recognizing a light signal emitted from the first active light source;
- and
- a marker applied on the load and operatively connected to the sensor, said marker including a second active light source for sending a light signal to the camera, when the sensor detects the light signal from the first active light source.
