Abstract
A device, method and software program for sensor self-calibrating are disclosed, including sensing, by sensors, objects in at least one field of view and generating sense data from the sensing; detecting, from the sense data, at least one marker disposed in a fixed position within the at least one field of view; for each marker detected, extracting position information of the marker and associating the marker with the extracted position information therefor; and calibrating the sensors based upon the extracted position information for each marker detected.
Claims22
A monitor device, comprising:
- a processing unit;
- memory coupled to the processing unit;
- a sensor arrangement coupled to the processing unit, the sensor arrangement comprising a plurality of sensors configured to sense objects in at least one field of view of the sensors;
- and
- program code stored in the memory and having instructions which, when executed by the processing unit cause the processing unit to
- receive, from the sensors, sense data of objects in the at least one field of view of the sensors;
- detect, in the sense data, at least one marker disposed in a fixed position within the at least one field of view;
- for each marker detected, extract position information between the marker and the monitor device, and associate the marker with the extracted position information;
- and
- calibrate the sensors in the sensor arrangement based upon the extracted position information.
A method, comprising:
- sensing, using sensors, one or more first objects in at least one field of view and generating sense data from the sensing;
- detecting, from the sense data, at least one marker disposed in a fixed position within the at least one field of view;
- for each marker detected, extracting position information corresponding to the marker relative to the sensors, and associating the marker with the extracted position information therefor;
- and
- calibrating the sensors based upon the extracted position information for each marker detected.
A software program stored in a non-transitory medium and having instructions which, when executed by a processing unit coupled to a sensor arrangement, cause the processing unit to:
- receive, from the sensor arrangement, sense data of objects in the at least one field of view of the sensor arrangement;
- detect, in the sense data, at least one marker disposed in a fixed position within the at least one field of view;
- for each marker detected, extract position information between the marker and the monitor device, and associate the marker with the extracted position information;
- and
- calibrate sensors in the sensor arrangement based upon the extracted position information.
