A system (100) and a method for detecting events in a predetermined space is provided. The system consists of one or more of an imager (101), a range-finder (103) and a sound capturing device (115), as well as a calibration factor and a processer (104). Images (301-304) are taken of a space and corrected based on the appropriate calibration factor that is selected based on the output of the range-finder (115). The images are analyzed and compared to characteristics representative of certain events including falls. If the images match the particular characteristics, the system (100) concludes that an event has occurred and outputs this result. Sounds may be captured (115) and used alone or in connection with an image (301-304) to determine that an event of interest has occurred. An alarm (114) or other output will be generated if the system detects certain predetermined events. |
