  • Publication number: 20210019877
    Abstract: Provided is an in-vehicle stereo camera which enables the continuation of automated driving if failures occur during imaging. A pair of captured images 301, 302, which is captured by a pair of imaging units so that both contain an overlapping region, are acquired (S201), it is determined whether an abnormal region is present in at least one of the pair of captured images, and if an abnormal region is present, the degree of impact from the abnormal region on an object recognition process of an object recognition unit is diagnosed (S202), and the processing content of the object recognition process is updated according to the degree of impact (S203).

  • Publication number: 20200349366
    Abstract: The purpose of the present invention is to provide an onboard environment recognition device exhibiting high accuracy of measurement in a wider range of view fields. The present invention pertains to an onboard environment recognition device (1) that utilizes two cameras (100, 110) for sensing, wherein the onboard environment recognition device (1) is characterized in that: two camera view fields include a stereo-vision area and a monocular-vision area; and the device laterally searches for parallax images that are output results of the stereo-vision area, estimates a road surface distance in the stereo-vision area, and measures the distance of the monocular-vision area by using the estimated road surface distance after extending the same to the monocular-vision area in the lateral direction.

  • Patent number: 10796167
    Abstract: Provided is a periphery recognition device that makes it possible to: minimize the load from object recognition processing for recognizing an object moving between one region covered by a long-distance sensor and/or a wide-angle short-distance sensor to another such region; the periphery recognition device being able to reduce the proportion of non-recognition or erroneous recognition of objects moving from a region covered by the long-distance sensor or the wide-angle short-distance sensor to a boundary region.
