    摘要： An image processing method according to an embodiment of the present invention has the following steps: the multi-viewpoint image input step for inputting images obtained from a plurality of viewpoint positions arranged on different straight lines, the detection step (2, 7, 17, 8) for detecting a viewpoint position and its view direction in which a user is seeing at the viewpoint position, and the image generation step (11, 12, 13, 8) for generating a virtual image viewed from the predetermined viewpoint by using the images input in the multi-viewpoint image input step on the basis of the detected predetermined viewpoint position and the view direction. In the image generation step, optimal corresponding points are obtained by detecting a straight line having a width on an epipolar plane image corresponding to the input images, thereby generating an image.

    摘要： Upon observation of multi-viewpoint images, even when the viewpoint moves continuously, the image cannot normally be displayed in correspondence with the continuous movement of the viewpoint, and an image from a viewpoint closest to the current viewpoint is displayed. To prevent this, each two adjacent images of the multi-viewpoint images are interpolated by detecting corresponding pixels and generating an interpolated image in accordance with the correspondences among pixels. The interpolated image is generated in such a manner that an epipolar plane image is generated by juxtaposing corresponding lines of the multi-viewpoint image, straight lines are detected from the epipolar plane image, and the intersecting points between interpolated lines and the detected straight lines are detected as interpolated pixels. In this case, as for a point for which a straight line cannot be detected, a straight line passing the point is estimated, thereby generating an interpolated pixel. When a plurality of straight lines are detected for a pixel of interest, the priority level is assigned to the pixel of interest in correspondence with the number of detected straight lines. When the priority level is smaller than that of another pixel through which the detected straight line passes, the straight line is ignored, and an interpolated pixel is not generated.

    摘要翻译： 在观察多视点图像时，即使视点连续移动，与视点的连续移动对应地不能正常地显示图像，并且显示来自最接近当前视点的视点的图像。 为了防止这种情况，通过检测相应的像素并根据像素之间的对应关系产生内插图像来内插多视点图像的每两个相邻图像。 以这样的方式生成内插图像，即通过并列多视点图像的相应行来生成对极平面图像，从极坐标图像检测直线，并且插入线与检测到的直线之间的交点是 检测为内插像素。 在这种情况下，对于不能检测到直线的点，估计通过该点的直线，从而生成内插像素。 当针对感兴趣的像素检测到多条直线时，根据检测到的直线的数量将优先级分配给感兴趣的像素。 当优先级小于检测到的直线通过的另一像素的优先级时，忽略直线，并且不产生内插像素。
