摘要： Provided is an object detection device capable of reliably recognizing a vehicle. This object detection device detects multiple three-dimensional objects from a left image and a right image captured with a left imaging unit and a right imaging unit (S103), extracts, as combination candidates from among the multiple three-dimensional objects, two three-dimensional objects which exist with an interval to the left/right, and determines whether a sparse parallax region, which is a region having a smaller parallax density than left/right regions, exists in an intermediate region between the two three-dimensional objects extracted as combination candidates. Then, the regions of two three-dimensional objects (for which it has been determined that a sparse parallax region exists in the intermediate region, and which have tentatively been identified as a single three-dimensional object) are extracted respectively from the left and right images and compared to each other, a determination is made regarding whether the perspective is the same, and when it is determined that the perspective is the same, the two three-dimensional objects are determined to be a single three-dimensional object.

摘要： An onboard environment recognition device is obtained with which it is possible to improve recognition performance within the headlight illumination range and outside the headlight illumination range of a vehicle with an onboard camera. This onboard environment recognition device has: an imaging unit 100 for imaging, using a camera installed in the vehicle, at a wider-angle range than the headlight illumination range; an in-illumination/out-of-illumination exposure adjustment unit for setting appropriate exposure conditions separately within the headlight illumination range and outside the headlight illumination range; and a recognition unit 500 for recognizing images on the basis of the acquired images. Therefore, it is possible to maintain high recognition performance in the boundary regions of the headlight illumination range, and outside the range, and the present invention can also be used for wide-angle sensing at night.

摘要： Provided are a travel route recognition device and a travel assistance system using the same, which are capable of precisely recognizing the positions of white lines and road boundaries even if, for example, there is a decrease in the accuracy of the detection of both white lines and road boundaries on the travel route. The direction of the travel route is estimated on the basis of the direction of a linear site included in an image obtained by imaging units, and the direction of the boundaries of a surface region included in a distance image comprising three-dimensional distance information generated on the basis of the images obtained by the imaging units or on the basis of distance information detected by the distance detection unit.
