3D - a camera according to the stereo copy principle and method for detecting of deep cards

摘要

It is a 3d - camera (10) according to the stereo copy principle for the detection of low cards (52) of a monitored zone (12) is specified, the at least two camera modules (14a, b), each with an image sensor (16a, b) in perspective, which are offset relative to each other for receiving of two-dimensional in (42) as well as a stereo copy unit (28) which, for the use of a stereo copy algorithm for generating a depth card (46, 50) is formed by corresponding portions each other in two offset perspective recorded two-dimensional images are recognized within a disparity area and whose distance is calculated on the basis of the disparity. In this case, a pixel together mount, a unit (30), in order, by combining, in each case, a plurality of pixels from a two-dimensional image (42) a two-dimensional intermediate image (48) to generate a lower resolution, as well as a fusion a unit (32) is provided, which at least two low cards (46, 50) to a common depth card (52) is fused, wherein at least one of the low cards (50) of intermediate images (48) is generated.
