Abstract: In an apparatus for monitoring surroundings of a vehicle, a road surface recognizer recognizes from an image of surroundings of the vehicle captured by a camera, a road surface on which the vehicle can travel. A travel trajectory estimator estimates a travel trajectory from a current location of the vehicle based on a steering state of the vehicle. A travelable degree calculator calculates, based on the travel trajectory estimated by the travel trajectory estimator and a result of recognition of the road surface by the road surface recognizer, a travelable degree that is a degree to which the vehicle can travel on the road surface. A notifier provides a notification of the travelable degree calculated by the travelable degree calculator.

Abstract: An obstacle detection apparatus includes a distance measuring sensor, an imaging section, and a control section. Based on a reception result of reception waves obtained by the distance measuring sensor, the control section acquires an estimated reflection position in an illuminated region already irradiated with search waves. Based on the estimated reflection position, the control section recognizes an outer shape of an obstacle. Based on an imaging result obtained by the imaging section, the control section performs image recognition of the obstacle. Based on a recognition result of the outer shape of the obstacle and a result of the image recognition, the control section acquires a relative position, with respect to a vehicle, of a portion of the obstacle in an image captured by the imaging section included in a non-irradiated region ahead of the illuminated region in a vehicle traveling direction.

Abstract: A parking assistance device is applied to a vehicle equipped with a camera for capturing an image of an area in front of the vehicle and is configured to assist forward parking of the vehicle in a parking space. The parking assistance device includes: a position estimation unit which, in a situation where the vehicle is advancing toward the parking space in a lateral passage of the parking space, estimates, based on an image captured by the camera, at least one of a first corner position, which is a near-side corner position at a vehicle entrance part of the parking space, and a second corner position, which is a far-side corner position at the vehicle entrance part, before the vehicle passes by the parking space; and a space recognition unit which recognizes the parking space for forward parking based on the at least one estimated corner position.

Abstract: A parking assisting apparatus includes an imaging unit acquiring image information corresponding to an image of surroundings of a vehicle, an image processing section recognizing a feature shape in the image by processing the image information, an obstacle detecting section acquiring positional-relationship information corresponding to a positional relationship between the vehicle and an obstacle present around a parking space, and a manner-of-parking selecting section selecting a manner of parking the vehicle in the parking space from manner candidates including perpendicular parking and parallel parking based on the feature shape and the positional-relationship information. The manner-of-parking selecting section selects the manner of parking from the manner candidates by integrating a likelihood of each of the manner candidates based on the positional-relationship information with a likelihood of the manner candidate based on a recognition result to calculate final likelihoods of the respective manner candidates, and by comparing the calculated final likelihoods.

Abstract: An onboard image generator is provided. The onboard image generator includes a first camera capturing an image in front of or behind a vehicle, and a second camera and a third camera capturing images on right and left sides of the vehicle, respectively. Based on the images captured by the second and third cameras, a first viewpoint converter generates a set of symmetrical viewpoint conversion images shaped viewed toward the front or rear of the vehicle from a pair of parallel virtual viewpoints. Based on the image captured by the first camera, a center image generator generates a center image. A combined image generator generates a combined image by arranging the center image in a center of and arranging the set of viewpoint conversion images besides the center image.

A three-dimensional object recognition unit is configured to recognize a three-dimensional object in the captured image. A superimposition-image acquisition unit is configured to acquire a superimposition image that represents the three-dimensional object recognized by the three-dimensional object recognition unit, by performing a process depending on a type of the three-dimensional object recognized by the three-dimensional object recognition unit. A superimposition unit is configured to superimpose, onto the bird's-eye view image, the superimposition image acquired by the superimposition-image acquisition unit, at a position where the three-dimensional object is present in the bird's-eye view image.

Abstract: An image processing unit identifies the shape of an obstacle that is identified from an area that appears in a peripheral image based on an image captured by a camera. The shape of the obstacle includes at least a tilt of a section of the obstacle in a road-surface direction. The section of the obstacle faces a vehicle. The image processing unit generates a superimposed image in which a mark image that is generated as a pattern that indicates the identified obstacle is superimposed onto a position that corresponds to the obstacle in the peripheral image. At this time, the image processing unit variably changes properties of the mark image based on the tilt of the obstacle identified by an obstacle identifying unit. The image processing unit then displays the generated superimposed image on display apparatus.

Abstract: In an object detection device to be installed to a vehicle and detect an object outside the vehicle, a position calculator sets multiple candidate points representing a candidate position of the object, based on positions of feature points extracted from a first image captured at a first time. The multiple candidate points are set to be denser within a detection range set based on a distance to the object detected by the ultrasonic sensor than outside the detection range. The position calculator estimates positions of the multiple candidate points at a second time which is after the first time, based on the positions of the multiple candidate points and movement information of the vehicle, and calculates the position of the object by comparing the estimated positions of the multiple candidate points at the second time and the positions of the feature points extracted from a second image captured at the second time.
