Abstract
An object detection method and apparatus is disclosed, where the object detection method includes determining a weather condition based on a noise floor measured in an elevated direction, and detecting an object based on comparing a signal level of a target signal measured in a depressed direction and a threshold level corresponding to the determined weather condition.
Claims26
An object detection method comprising:
- determining a weather condition based on a noise floor measured by a first radar sensor from among radar sensors arranged separately from one another, in response to a reference signal emitted from a second radar sensor from among the radar sensors;
- and
- detecting an object based on comparing a threshold level corresponding to the determined weather condition and a signal level of a target signal measured by the first radar sensor.
An object detection apparatus comprising:
- radar sensors arranged separately from one another and comprising a first radar sensor configured to receive a signal emitted from a second radar sensor;
- and
- a processor configured to determine a weather condition based on a noise floor measured by the first radar sensor, in response to a reference signal emitted from the second radar sensor, and to detect an object based on comparing a threshold level corresponding to the determined weather condition and a signal level of a target signal measured by the first radar sensor.
An apparatus for detecting an object of interest comprising:
- radar sensors arranged at a distance one another;
- a first radar sensor of the radar sensors configured to receive a signal emitted from a second radar sensor of the radar sensors;
- a head-up display (HUD);
- a processor configured to
- determine a weather condition based on a noise floor measured by the first radar sensor, in response to a reference signal emitted from the second radar sensor in an elevated direction,
- detect an object based on comparing a threshold level corresponding to the determined weather condition and a signal level of a target signal measured by the first radar sensor, the target signal being emitted by the second radar sensor in a depressed direction, and
- output the object through the HUD.
