  • Publication number: 20200082184
    Abstract: An object detection device acquires a plurality of images captured by a camera mounted in a moving body and acquires movement information of the camera. The object detection device extracts an edge from a first image among the acquired images. The object detection device calculates a plurality of candidate points corresponding to the edge in a second image, based on the movement information and calculates candidate points corresponding to a plurality of heights as height candidates of the edge. The object detection device calculates a correlation index value between the edge and each of the plurality of candidate points and detects the candidate point with the largest correlation as a correspondence point of the edge. The object detection device detects an object at a position of the edge when the correlation index value of the detected correspondence point is equal to or smaller than a predetermined threshold.

  • Patent number: 9956956
    Abstract: A vehicle system for a vehicle can include sensors and a controller. The sensors can detect a position and speed of the vehicle and a position and speed of an object adjacent to the vehicle's lane. The controller can determine an operational state based on input from the sensors. The controller can operate the vehicle in an autonomous mode, wherein the controller controls the speed of the vehicle and a spacing between the vehicle and the object. The controller can switch from the autonomous mode to a learning mode in response to a driver taking control of the vehicle's speed or steering. In the learning mode, the controller can learn a preferred spacing between the vehicle and the object and a preferred speed relative to the object. The controller can control the vehicle in the autonomous mode based on the preferred spacing and speed during similar operational states.

  • Patent number: 9626765
    Abstract: A position detection device obtains image coordinate groups representing a coordinate of a target object in each acquired image having first and second acquired image groups. The first acquired image group has acquired images obtained at an image acquiring timing in a reference period. The second acquired image group has acquired images obtained at an image acquiring timing in the reference period, which is delayed from the image acquiring timing of the first acquired image group by an asynchronous time. The device performs a Fourier transformation of each of a first locus and a second locus, and calculates a first frequency waveform based on the first locus and a second frequency waveform based on the second locus. The device calculates a position of the target object based on a relationship in which the frequency waveforms are delayed relative to each other by a phase corresponding to the asynchronous time.
