Abstract
The present disclosure provides a method including memorizing a sequence of high-resolution images of a scene in a buffer, obtaining radiation emission readings from one or more photo detectors, detecting a suspected flash event based on processing the radiation emission readings from the one or more photo detectors. The method may further include that the detecting occurs at a first instant, retrieving from the buffer high-resolution images of the scene including at least one image that was captured prior to said first instant, and processing the high-resolution images of the scene to determine a geolocation of the suspected flash event.
Claims20
A method comprising:
- obtaining a sequence of high-resolution images of a scene;
- processing the radiation emission readings from one or more photo detectors to detect a suspected flash event;
- and
- processing the high-resolution images to determine whether the suspected flash event is an event of interest or not, wherein the determining of whether the suspected flash event is an event of interest or not comprises applying motion processing to the high-resolution images to identify a moving object in the scene and determining whether the suspected flash event is associated with glint from said moving object.
A method comprising:
- obtaining a sequence of high-resolution images of a scene;
- processing the radiation emission readings from one or more photo detectors to detect a suspected flash event;
- and
- processing the high-resolution images to determine a location of the suspected flash event, wherein the determining of the location of the suspected flash event comprises retrieving, from the sequence of high-resolution images, at least one image without the suspected flash event and at least one image with the suspected flash event, and subtracting the at least one image without the suspected flash event from the at least one image with the suspected flash event by utilizing a block-by-block motion correction to remove background from the image with the suspected flash event and thereby locating the suspected flash event within the image.
A system comprising:
- a frame buffer capable of memorizing a sequence of high-resolution images of a scene;
- one or more photodetectors capable of obtaining radiation emission readings from the scene;
- a controller connectable to the one or more photodetectors, which provide radiation emission readings from the scene, and configured and operable for detecting a suspected flash event based on processing the radiation emission readings from the one or more photo detectors, wherein the controller is configured for determining whether the suspected flash event is an event of interest or not, by applying motion processing to the high-resolution images of the scene to identify a moving object in the scene, and determining whether the suspected flash event is associated with glint from said moving object.
