摘要： Optoelectronic head comprising an optical reception system (lens 1, mirror 2) rotationally driven about a vertical axis (B'B) so as to form on a photosensitive surface (8) a punctual image which scans said surface at X and whose mirror (2) pivots with respect to the horizontal plane so that said image scans the photosensitive surface at Y. A variable opening diaphragm (5) limits the vertical reception angle. An electronic device (14) allows to acquire extreme coordinates of the two scannings for location purposes.

摘要： A sensor for detecting the intensity and the angle of incidence ( alpha ) of solar radiation has a plurality of identically oriented photo-elements (12) arranged in a plane on an exposure surface (13) so as to form a grid. An optical arrangement (11, 15) arranged above the exposure surface (13) directs the solar radiation passing through a measurement opening onto various areas of the exposure surface (13), depending on the angle of indicence ( alpha ). Since all photo-elements are arranged in a plane, a great number of photo-elements may be arranged in a very small space as a CCD image sensor or as optoelectronic multiple chip array. It is also possible to integrate them on a chip with other electronic components and modules for evaluating the received signals. The angle of incidence of the solar radiation and the lighting intensity may be detected with a very high resolution.

摘要： An imaging target tracker and a method for determining thresholds that are used to optimally distinguish a target from background. The present invention is an imaging target tracker that comprises a likelihood-based threshold selection method that uses knowledge of the location of a target to build up temporally-smoothed grey-level distribution or likelihood maps. Inner and outer histograms are formed that comprise inner and outer regions of an image, respectively, using inner, buffer and outer gates that segment the image. The inner and outer histograms are then recursively smoothed. A lookup table of actually observed pixel values is formed. A target likelihood value for actually observed pixel values is then computed. Legal start and end points of histogram segments are identified. Valid histogram segments are identified. The longest histogram segment is identified. Finally, two optimal thresholds are selected (8) and are set at respective ends of histogram segments. The likelihood maps adapt over time to the signature of the target. The grey-level distribution of the target is used to select thresholds that pass a band of grey levels whose likelihood that they belong to the target is high.

摘要： A method and apparatus are disclosed for detecting moving objects silhouetted against background clutter. A correlation subsystem (12) is used to register the background of a current image frame (framestore 1) with an image frame taken two time periods earlier (framestore 3). A first difference image is generated by subtracting the registered images, with the first difference image being filtered by low pass filter (34) and thresholded by a three level segmenter (36). A second difference image is likewise generated between the current image frame and another image frame taken at a different subsequent time period. This second difference image is likewise filtered and thresholded. The two difference images are logically ANDed together by gate (39) whose output is connected to a formatter, sorter and feature extractor (40). Track files are generated in CPU (16) for comparing subsequently extracted image features with previously stored extracted features.

摘要： A software-based resolver-to-digital converter (RDC)(80) for computing an angle of rotation theta of gimbal-mounted instrumentation (16) in a gimbal system. The RDC (80) computes the angle of rotation of the instrumentation using parameter signals received from a resolver (32) in the system. The parameter signals, along with a resolver reference signal are input into a multiplexor (60) and are multiplexed. The signals are then fed to an analog-to-digital converter (38) and converted to digital form. The digital signals are then input into a processor (36) associated with the system. This processor, in addition to performing numerous system computations, is programmed through appropriate software to filter the digital signals received, compute the value for the angle of rotation theta using a Fourier transform and output the computed value to system circuitry (31) for processing to enhance system operation. The present invention eliminates the need for additional resolver-to-digital converter hardware components (40, 42, 44), as the converter (80) is implemented at the existing system processor (36).

摘要： An image recording system consists of two fixed sensors (1a, 1b) which record image data, which are A/D converted and transformed to three-dimensional information. The three-dimensional information is used for controlling a movable camera (2) which is capable of panning, tilting, zooming and focussing. The sensors (1a, 1b) extract image data in the close IR spectrum, the IR light source emitting light to the scene from which image data are to be recorded. Further, a high-pass or band-pass filter is provided in the fixed optoelectronic sensors.

摘要： A performance measure of an ATR (automatic target recognition system) is made from ancillary target data and the ATR output. A parameter of the ATR is varied to determine the change in ATR performance due to the parameter variation. Separate performance in the form of a quadratic equation models provide performance as a function of parameter and metrics. The performance models is partially differentiated with respect to the parameter. The partial differentiation allows solution for the estimated metric.
