The embodiment of the invention provides a method, device and equipment for determining installation positions of ultrasonic sensors. The method comprises the steps of: acquiring performance parameters of to-be-installed ultrasonic sensors; acquiring contour parameters of a target vehicle; acquiring detection required parameters which the ultrasonic sensors need to reach on the target vehicle; andaccording to the performance parameters, the contour parameters, the detection required parameters and preset constraint conditions, determining an installation position of each ultrasonic sensor, wherein the installation position comprises installation coordinates and an installation angle. When the installation positions are determined, the performance parameters of the ultrasonic sensors, thecontour parameters of the target vehicle and the detection required parameters are simultaneously considered, so that the method for determining the installation positions of the ultrasonic sensors, which is provided by the embodiment of the invention, is applicable to a random vehicle type and a random type of ultrasonic sensor, and has universality.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of automatic driving, and in particular, to a method, device, and device for determining the installation position of an ultrasonic sensor. Background technique [0002] Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals. Due to their low cost, they have become an essential sensor for systems such as parking or assisted parking. In the parking or assisted parking system, the ultrasonic sensor sends out ultrasonic waves through the transmitter, and receives the ultrasonic waves reflected back by the obstacles through the receiver. distance from the obstacle. Ultrasonic sensors provide safety checks for vehicles by sensing obstacles in the environment. [0003] In order to ensure that the detection blind area of the vehicle is as small as possible, it is necessary to set up multiple ultrasonic sensors, and arrange the installation positions of eac...
