Abstract (en)
[origin: WO2016075138A1] The invention relates to a rail vehicle (1) comprising an image generation system for detecting an area outside the rail vehicle (1). The image generation system has four image generation devices (2, 3, 4, 5), which generate two-dimensional images of the area. A first (2) and a second (3) of the four image generation devices (2, 3, 4, 5) are arranged at a first distance from one another and form a first stereo pair (2, 3). The third (4) and the fourth (5) of the four image generation devices (2, 3, 4, 5) are arranged at a second distance from one another and form a second stereo pair (4, 5), wherein the first distance is greater than the second distance. To increase the reliability of the vehicle, particularly during driverless operation, the image generation system has an evaluation device which receives image data from the four image generation devices (2, 3, 4, 5). If evaluation of image data from a failed and/or faulty image generation device (2; 5) is not possible or erroneous, the evaluation device is designed to use the image data from three other (3, 4, 5; 2, 3, 4) of the four image generation devices (2, 3, 4, 5), which three contain a first stereo image pair and a second stereo image pair, wherein the first stereo image pair corresponds to the image data from two of the three other image generation devices (3, 4, 5; 2, 3, 4), which two are arranged at a third distance from one another, and the second stereo image pair corresponds to the image data from two of the three other image generation devices (2, 3, 4, 5), which two are arranged at a fourth distance from one another, and wherein the third distance and the fourth distance are different sizes.
