The method involves capturing a picture of a vehicle (101) from another vehicle (102) using a video camera (122), in a direction of a vehicle longitudinal axis (112) of the vehicle (102). A wall surface of the vehicle (101) is detected by determining edges from the picture, where the edges run horizontally in the picture and are arranged over each other. An orientation angle of the wall surface relative to a picture recording direction (132) is calculated based on the relative inclination between the determined edges using an angle calculation unit (126). An independent claim is also included for a device for determining relative yaw angle between two vehicles, comprising a camera.

The transmission signal generator generates transmission signals modulated with a linear modulation component (Ma) and a cyclic modulation component (Mb). The linear component changes the frequency of the transmission signal with respect to time. The cyclic component changes the frequency of the transmission signal with a cyclic frequency, which is greater than twice a frequency of the drift signal.

Even if the fundamental wave target to be detected is undetected within a close range, data on the fundamental wave target is estimated and outputted on the basis of the interpolated target calculated from the second-order wave target which continues being detected, as described above.

A baseband signal down-converted by a frequency converter ( 152 ) is output to a signal processing section ( 102 ) through a board-to-board connector ( 103 ) after passing through a delay circuit ( 153 ). Still further, a control signal is output to a switching circuit ( 151 ) from a control signal generating section ( 162 ) through the board-to-board connector ( 103 ). The delay circuit ( 153 ) increases a time lag from when the control signal passes through the board-to-board connector ( 103 ) until when the baseband signal passes through the board-to-board connector ( 103 ) by applying a predetermined delay time to the baseband signal. Thereby, the baseband signal receives no interference from the control signal.

Vehicle sensor calibration using sensor calibration targets

Номер: US20210004985A1
Принадлежит: GM Cruise Holdings LLC

Sensors coupled to a vehicle are calibrated using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. The sensors capture data at each vehicle orientation along the rotation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, and calibrates the sensor based on these representations, for example by comparing these representations to previously stored information about the sensor targets and generating a correction based on differences, the correction applied to post-calibration sensor data.
