The invention provides an ultrasonic wave vehicle pose and position detection method and system. One side of a parking spot is provided with an ultrasonic wave diastimeter and a driving motor drivingthe ultrasonic wave diastimeter to rotate. The method comprises the following steps that the ultrasonic wave diastimeter respectively measures the distance between two measuring points at a first sideedge and the ultrasonic wave diastimeter; the ultrasonic wave diastimeter respectively measures the distance between two measuring points at a second side edge and the ultrasonic wave diastimeter, wherein the first side edge and the second side edge of the vehicle have a common end point; based on the distance data returned from the ultrasonic wave diastimeter, a linear equation at the first sideedge of the vehicle and a linear equation at the second side edge can be respectively calculated; a coordinate value of the common end point can be determined based on the linear equation at the first side edge of the vehicle and the linear equation at the second side edge. The invention is advantageous in that the pose and position of the vehicle in a parking spot can be detected through the ultrasonic wave diastimeter; the detection process can be convenient and fast; data basis can be provided for an automatic charging device or a pose and position adjusting mechanism.
Description
technical field [0001] The invention relates to the technical field of vehicle detection, in particular to an ultrasonic vehicle pose detection method and system. Background technique [0002] The rise of the time-sharing rental business of electric vehicles has brought convenience to the people to a certain extent. Users can easily take shared electric vehicles, and the point of taking and returning the car does not need to be consistent, which meets the needs of users for travel, and It is very flexible to use. [0003] In order to further facilitate the user's use, there is now an automatic charging device. After the user parks the vehicle at the designated parking position, the automatic charging device can automatically identify the position of the charging port of the vehicle, and control the mechanical arm according to the position of the charging port. The charging gun charges the electric vehicle. However, in a parking garage using automatic charging equipment, if...
