Abstract

The embodiment of the invention discloses a method and a device for determining the height of a target object and vehicle-mounted radar equipment, which are used for determining the height of the target object while detecting the target object. The method for determining the height of the target object comprises the following steps: transmitting a wireless detection signal; receiving a reflectionsignal generated by reflecting the wireless detection signal by the target object; and determining that the height of the target object is higher than a preset height threshold when it is determined that at least two reflection signals with signal values greater than a preset amplitude threshold are received within a preset duration.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a method, device, equipment, medium and vehicle-mounted radar equipment for determining the height of a target object. Background technique [0002] The automatic parking assist system is a system produced to realize automatic parking. In recent years, automatic parking assistance systems have been widely used in vehicles produced by major manufacturers. [0003] Different automatic parking assistance systems can use different methods to detect objects around the vehicle. Take the use of sensors or radar to detect objects around the vehicle as an example. In practical applications, it is installed around the front bumper and rear bumper of the vehicle. A sensor or radar that acts as both a signal transmitter and a signal receiver. After the automatic parking assist system is activated, the sensor or radar will send a detection signal around the vehicle. When the detection si...
