Abstract: A device (800) for protecting an aircraft against missiles, includes a Short-Wave InfraRed based (SWIR-based) Missile Tracking Unit (801), having a SWIR-based optical imager (802) that associated with an optical SWIR band filter (803). The device (800) further includes a SWIR signals processor (804); it analyzes the captured SWIR optical signals; and it performs a SWIR-based missile acquisition process, which is also based on raw angular position data of a missile as received from a Missile Approach Warning System (MAWS); and it performs a SWIR-based missile tracking process, which continuously and dynamically determines a precise angular position of the missile based on the captured SWIR optical signals. The device (800) includes a laser-based missile-jamming unit (805), having an internal laser emitter (806); and optionally also being operably associated with an external high-power laser emitter (807); to disrupt the missile, or to disrupt a guiding station of the missile.

Abstract: A system and method for moving target based non-uniformity calibration for optical images. The described approach allows for the use of the same test chamber to perform non-uniformity calibration and moving target tests. The current approach works by scanning a test scene having a target and a background at different intensity levels in an overlapping pattern across the imager FOV and cross-referencing multiple measurements of each pixel of a test scene as viewed by different pixels in the imager; each fully-compensated image pixel sees multiple different scene pixels and each scene pixel is seen by multiple imager pixels. For each fully-compensated imager pixel, an Nth order correlation is performed on the measured and estimate pixel response data to calculate the NUC terms. This approach is based on the simple yet novel premise that every fully-compensated pixel in the array that looks at the same thing should see the same thing.

Abstract: A method and system for determining extrinsic calibration parameters for at least one pair of sensing devices mounted on transportable apparatus obtains (202) image data (110) representing images captured by an image generating sensing device (102) of the pair at a series of poses during motion through an environment (120) by transportable apparatus (100). The method obtains (202) data (112) representing a 3D point cloud based on data produced by a 2D LIDAR sensing device (104) of the pair. The method selects (204) an image captured by the image at a particular pose. The method generates (210) a laser reflectance image based on a portion of the point cloud corresponding to the pose. The method computes (212) a metric measuring alignment between the selected image and the corresponding laser reflectance image and uses (214) the metric to determine extrinsic calibration parameters for at least one of the sensing devices.

Abstract: A light tracking sensor and a sunlight tracking system including the same, the light tracking sensor comprises two or more light tunnel devices. One end of the respective light tunnel devices form a common single-point micro-hole acting as an input port for directional light, the other ends of the light tunnel devices act as output ports for directional light and is provided with light-sensing units respectively. A sunlight tracking system is constituted of said light tracking sensor, a differential processing unit, an A/D converting unit, a microprocessor unit, a driving unit and an executive unit driven by the output end of the driving unit. Since one ends of the light tunnel devices form a common single-point micro-hole and the surface around the micro-hole is a curved surface, the sunlight tracking system, compared with the prior art, has a simpler structure, and a higher integration; Meanwhile, when in combination with certain software, a fast, accurate sunlight racking can be achieved, and its tracking precision is less influenced by the outdoor environment.

Abstract: In a test method in which an image photographed by a camera apparatus 1 attached to a body of a vehicle is displayed on a display device 17 and an examiner examines compliance or non-compliance of the shooting direction of the camera apparatus 1 by comparing the position of a reference pattern and the position of a judgment pattern on the displayed photographed image, the photographed image is obtained at first by photographing with the camera apparatus 1 a test chart which is placed at a predefined position ahead of the vehicle with the reference pattern drawn on the test chart. Next, the judgment pattern is set at a specific position on the photographed image. Then, the photographed image on which the judgment pattern has been set is displayed on the display device 17.
