Abstract: An object of the present invention is to obtain a vehicle control device capable of guiding a host vehicle to a narrow area by low-speed automatic driving by quick and precise positioning of the host vehicle, and guiding the host vehicle to a stop position of which details are unknown by designating each stop frame by beacons. A vehicle control device 101 according to the present invention includes a wireless reception unit 121 that receives radio waves through a plurality of antennas 102 mounted on a host vehicle 100, the radio waves being transmitted from a plurality of beacons 201, a position information acquisition unit 122 that obtains position information of the beacons using orientation information of the radio waves received by the wireless reception unit, and a guidance area estimation unit 124 that sets a diagonal line 301 of a rectangular area 302 from the position information and estimates a guidance area 312 from the diagonal line.

Abstract: The present disclosure provides an in-vehicle camera calibration device, a control device, and a pattern-with-a-beacon capable of performing calibration of a camera mounted on a vehicle more accurately and easily. The in-vehicle camera calibration device 100 includes a control device 110 to be mounted on a vehicle 200 and a pattern-with-a-beacon 120 to be installed outside the vehicle 200. The pattern-with-a-beacon 120 includes a calibration pattern 121 captured by the camera 201 mounted on the vehicle 200 at the time of calibration, and a beacon 122 that transmits beacon information Ib by wireless communication. The control device 110 calibrates the camera 201 based on the pattern image Gp that is the image of the calibration pattern 121 acquired from the camera 201 and the beacon information Ib received through the receiving antenna 202 mounted on the vehicle 200.
