Abstract:
A system and method for filtering LiDAR data is provided. The system includes a LiDAR data collector that is configured to collect the LiDAR data from a LiDAR and store the LiDAR data in a matrix structure. A noise point determiner is configured to determine whether a first filtering condition for determining whether a point within a predetermined reference distance in the LiDAR data is present, a second filtering condition for determining whether a present point adjacent to a left and right by a reference of a reference point in the matrix structure is a first reference value or less, and a third filtering condition for determining whether a present point adjacent to a top and bottom by the reference of the reference point is a second reference value or less are satisfied.
Abstract:
An apparatus and method for identifying surrounding vehicles is provided. The apparatus includes a sensor that measures position coordinates of a first surrounding vehicle and a yaw rate and a speed of a subject vehicle and a V2V communication unit that receives a coordinate history and a speed from the plurality of surrounding vehicles. Additionally, a controller generates a traveling trajectory and a speed pattern as first identification information by applying accumulated behaviors of the subject vehicle to the position coordinates of the first surrounding vehicle and calculate each traveling trajectory and speed pattern as n-th identification information based on the coordinate history and the speed received via the V2V communication unit. The controller then compares the first identification information with the n-th identification information to recognize the surrounding vehicle corresponding to identification information most similar to the first identification information as the first surrounding vehicle.
Abstract:
An apparatus for a self localization of a vehicle includes a sensor unit, a landmark detector, a landmark recognizer, and a location estimator. The sensor includes at least two sensors and is configured to measure information on environment around the vehicle using each of the at least two sensors. The landmark detector is configured to detect landmark information based on data measured by each sensor. The landmark recognizer is configured to selectively combine landmark information detected based on data measurement of at least one of the at least two sensors to recognize a landmark and reflect fused landmark information to update a probability distribution. The location estimator is configured to use the probability distribution updated by the landmark recognizer to estimate a self location of the vehicle.
Abstract:
A technique for controlling power for V2X communication is provided. The apparatus includes a reception message analysis process configured to analyze headers of reception messages received from communication apparatuses of roadside apparatuses and surrounding vehicles located around a vehicle, a message loss checking process configured to check whether or not loss of the reception messages occurs by counting sequential numbers included in the headers of the reception messages, a density analysis process configured to analyze a density for each of communication apparatuses located in a communication radius of preset transmission power from the vehicle when the message loss checking process determines that the loss of the reception messages occurs, and a transmission power determination process configured to determine transmission power for V2X communication by deducting the preset transmission power in units of reference power according to the density when the density around the vehicle exceeds a reference value.
Abstract:
A driving mode changing method and apparatus of an autonomous navigation vehicle that allows a driver to stably operate the autonomous navigation vehicle. The autonomous navigation vehicle may be stably operated by mounting an apparatus (a touch pad, a joystick, or the like) to operate the autonomous navigation vehicle on seats (a passenger seat and a rear seat) other than a driver seat of the autonomous navigation vehicle and providing various information (a near around view, a far around view, a critical level, vehicle information, and the like) to drive the autonomous navigation vehicle.

Abstract:
A method and an apparatus for detecting a pedestrian by a vehicle during night driving are provided, in which the apparatus includes: a first camera configured to take a first image including color information of a vicinity of the vehicle during night driving; a second camera configured to take a second image including thermal distribution information of the vicinity of the vehicle; a pedestrian detector configured to detect a non-pedestrian area by using the color information from the first image and detect a pedestrian area by excluding the non-pedestrian area from the second image; and a display configured to match and display the pedestrian area on the second image.
Abstract:
An apparatus and method for controlling a vehicle speed based on information about forward vehicles that travel in the same lane may be acquired using Vehicle to Everything (V2X) communications in a cooperative adaptive cruise control (CACC) system. The CACC system includes a communication unit receiving vehicle information from neighboring vehicles using V2V communications; an information collection unit collecting vehicle information of the neighboring vehicles and the subject vehicle using sensors; and a control unit determining a forward vehicle and a far-forward vehicle using the sensors, selecting first and second target vehicles for being followed by the subject vehicle based on the vehicle information of the forward vehicle and the far-forward vehicle and the vehicle information of the neighboring vehicles, and controlling the driving speed of the subject vehicle based on speed information of the first and second target vehicles.
Abstract:
A vehicle positioning apparatus and method are provided that are capable of more accurately measuring the position of a traveling vehicle without interoperating with a DGPS. The method includes calculating a position of the traveling vehicle based on coordinates of the respective GPS satellites shared by a surrounding vehicle and the traveling vehicle. In addition, a position coordinate is calculated of the surrounding vehicle measured by the reference of the traveling vehicle.
Abstract:
