    • A system and method for producing spectrally segmented images of object fields (16). In one embodiment the system includes an optical system (4) that focuses light received from an object field (16) along a focal plane with a field stop (20) positioned within the optical system (4) that has plural apertures for selectively transmitting the light from the object field (16). A diffractive element (24) is positioned within the optical system (4) to spectrally spread, along the focal plane, the light transmitted through the apertures. The apertures can be parallel slots (60) or geometrically arranges holes (106). The plural apertures are spaced such that the spectrally spread light transmitted through any given aperture and incident upon the focal plane does not overlap on the focal plane with the light transmitted through any other aperture. The diffractive element (24) may spread light across one or more directions. In one embodiment, a processor (8) is coupled to a plurality of pixels in a focal plane array (6). A memory (10) for storing image data organized as a hyper-spectral cube.
    • 一种用于产生对象区域(16)的频谱分割图像的系统和方法。 在一个实施例中,该系统包括一个光学系统(4),该光学系统(4)将焦距从物场(16)接收的光聚焦在位于光学系统(4)内的场挡板(20) 来自物场(16)的光。 衍射元件(24)位于光学系统(4)内,沿着焦平面光谱地扩散透过孔的光。 孔可以是平行狭槽(60)或几何排列孔(106)。 多个孔径被间隔开,使得透射通过任何给定孔径并且入射在焦平面上的光谱扩展的光在焦平面上不重叠,而透过任何其它孔的光。 衍射元件(24)可以在一个或多个方向上传播光。 在一个实施例中,处理器(8)耦合到焦平面阵列(6)中的多个像素。 一种用于存储组织为超光谱立方体的图像数据的存储器(10)。

    • A method for creating an oblique-mosaic image from a plurality of source images is disclosed. Initially, a desired area to be imaged and collected into an oblique-mosaic image is identified (18) and then a mathematical model of a sensor of a virtual camera (20) is created (22), where the virtual camera has an elevation greater than an elevation of the area to be imaged. The mathematical model has an oblique-mosaic pixel map for the sensor of the desired area. A surface location is determined for each pixel included in the oblique mosaic pixel map (24), and at least one source oblique image pixel of the area to be imaged is reprojected for each pixel included in the oblique-mosaic pixel map to thereby create an oblique- mosaic image of the desired geographical area (26). Further, techniques for compensating for building lean in oblique- mosaic images are disclosed (28).
    • 公开了一种用于从多个源图像生成倾斜马赛克图像的方法。 首先,识别要成像并收集到倾斜马赛克图像中的所需区域(18),然后创建虚拟相机(20)的传感器的数学模型(22),其中虚拟相机具有较大的仰角 比要成像的区域的高度。 数学模型具有用于所需区域的传感器的倾斜马赛克像素图。 针对包括在斜马赛克像素图(24)中的每个像素确定表面位置,并且对于包括在斜马赛克像素图中的每个像素重新投影要成像的区域的至少一个源倾斜图像像素,从而创建 所需地理区域的斜马赛克图像(26)。 此外,公开了用于补偿倾斜马赛克图像中的建筑物的技术(28)。
