An information processing apparatus includes a controller is configured to: identify a second vehicle traveling on a main lane behind a cutting-in position at which a first vehicle traveling on an acceleration lane cuts in; and perform at least any one of notifying the first vehicle of first guidance that prompts the first vehicle to merge into the main lane at a far end of the acceleration lane, and notifying the second vehicle of second guidance that prompts the second vehicle to assist the first vehicle in merging into the main lane.

Abstract: An information processing apparatus comprises a controller configured to execute periodically acquiring relative speed between two vehicles which are traveling on a same road; and performing predetermined processing in a case where a number of times that polarity of the relative speed is inverted in a first period exceeds a first threshold.

Abstract: This disclosure achieves smooth traffic. An information processing apparatus has a controller comprising at least one processor configured to perform: obtaining first data representing a driving tendency of a first vehicle; obtaining second data representing a driving tendency of each second vehicle located in the vicinity of the first vehicle; aggregating the second data corresponding to a plurality of the second vehicles thereby to generate reference data; and calculating a degree of similarity between the first data and the reference data thereby to notify a driver of the first vehicle when there is a deviation of a predetermined value or more between the first data and the reference data.

Abstract: An information processing apparatus is mounted on a vehicle. The information processing apparatus includes a control unit that is configured to determine whether or not a driver of the vehicle is driving dangerously, and perform, when it is determined that the driver of the vehicle is driving dangerously, a first control process of determining output of a machine mounted on the vehicle to be performed at a second value that is smaller than a first value in a normal state, the first value determined according to first information based on a stroke amount of an accelerator pedal.

Abstract: An information processing apparatus is mounted on a vehicle. The information processing apparatus includes a controller configured to detect whether or not the vehicle and a following vehicle are traveling on a same lane, determine whether or not the following vehicle is approaching at a speed faster than a speed of the vehicle, and output a guidance to change lanes, in a case where the vehicle and the following vehicle are traveling on the same lane, the following vehicle is approaching at a speed faster than the speed of the vehicle, and a guidance target exclusion condition is not satisfied.

Abstract: A camera parameter estimating method includes: obtaining a plurality of image frames in time series, the image frames being photographed by a camera installed in a mobile body; detecting at least one straight line from a central portion of a first image frame group including one or more first image frames among the plurality of image frames; detecting a plurality of curves corresponding to the straight line from a second image frame group including one or more second image frames at a later time than an image frame from which the straight line is detected based on a feature quantity of the detected straight line; and estimating a parameter of the camera based on the plurality of curves.

Abstract: In a vehicle control apparatus, a display device displays a vehicle image showing a vehicle shape viewed from a virtual view point, and a user interface accepts a user's operation. When the user interface accepts the user's operation that issues an instruction for changing the vehicle image, a display control unit causes the display device to display the vehicle image after the changing of the virtual view point. Simultaneously, the display control unit causes the display device to display command buttons corresponding to portions of the vehicle shown by the vehicle image after the changing of the virtual view point.

Abstract: This invention is to provide a technique for properly correcting video metadata related to and synchronized with the video. This video metadata correction apparatus includes: a section identification unit that identifies a section including incorrect video metadata based on information concerning video metadata in a first video metadata storage for storing the information concerning the video metadata as sensor information synchronized with video and a first video feature value, which correlates with the information concerning the video metadata and is extracted from the video; and a corrector that corrects the video metadata in the identified section based on the first video feature value or a second video feature value, which correlates with the information concerning the video metadata and is extracted from the video. In this manner, only an incorrectly measured part can be corrected in an effective manner.
