    • An image capturing apparatus previously captures a calibration image that serves as a reference when a distance to an object is calculated, and calculates, when an image of the object is captured using a monocular camera, the distance from the lens of the camera to the object using the calibration image and the distance from the lens of the camera to the calibration image. In this case, the image capturing apparatus measures the distance from the lens of the camera to one or more arbitrary points on the object, calculates the diffuse reflection coefficient of the object using the measured distance, the luminance on each of one or more arbitrary points, the distance to the calibration image, and the luminance, and calculates the distance to the object from the lens of the camera to the object using the calculated diffuse reflection coefficient.
    • 摄像装置预先拍摄当与物体的距离被计算时用作基准的校准图像,并且当使用单目相机拍摄被摄体的图像时,计算从照相机的镜头到物体的距离 使用校准图像和从相机镜头到校准图像的距离。 在这种情况下,图像拍摄装置测量从相机的镜头到物体上的一个或多个任意点的距离,使用测量的距离来计算被摄体的漫反射系数,一个或多个任意点的亮度 ,到校准图像的距离和亮度,并且使用所计算的漫反射系数来计算从相机的镜头到对象的物体的距离。

    • A night vision image processing unit (night vision apparatus) separates an input field image that a field separating unit has acquired from a near-infrared camera into an odd-numbered field image and an even-numbered field image. A region segmenting unit segments an image into a plurality of regions (a luminous region, a high-reflection region, a low-luminance region) based on luminance value of each pixel included in the odd-numbered field image and the even-numbered field image. A luminous region processing unit, a high-reflection region processing unit, and a low-luminance region processing unit correct the luminance value according to characteristics of the regions.
    • 夜视图像处理单元(夜视设备)将场分离单元已经获取的输入场图像与近红外摄像机分离成奇数场图像和偶数场图像。 区域分割单元基于奇数场图像和偶数场中包括的每个像素的亮度值将图像分割成多个区域(发光区域,高反射区域,低亮度区域) 图片。 发光区域处理单元,高反射区域处理单元和低亮度区域处理单元根据区域的特性校正亮度值。
