Abstract
A detection device includes: a sound wave sensor that detects a distance to a measurement target; and a processor configured to: in response to the measurement target being detected in a first detection range that is part of a detection range in which the distance to the measurement target is detectable by the sound wave sensor, change setting to cause a detection sensitivity for a second detection range in the detection range of the sound wave sensor to be a second detection sensitivity lower than a first detection sensitivity set before the setting is changed, the second detection range being outward of the first detection range when viewed from the detection device.
Claims14
A detection device comprising:
- a sensor that detects a distance to a measurement target;
- and
- a processor configured to:
- in response to the measurement target being detected in a first detection range that is part of a detection range in which the distance to the measurement target is detectable by the sensor, change setting to cause a detection sensitivity for a second detection range in the detection range of the sensor to be a second detection sensitivity lower than a first detection sensitivity set before the setting is changed, the second detection range being outward of the first detection range when viewed from the detection device, and
- in response to the measurement target being detected in the first detection range and the measurement target detected moving away from the detection device, change the setting to change the detection sensitivity for the second detection range from the second detection sensitivity to the first detection sensitivity.
A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
- in response to a measurement target being detected in a first detection range that is part of a detection range in which the distance to the measurement target is detectable by a sensor that detects a distance to a measurement target, changing setting to cause a detection sensitivity for a second detection range in the detection range of the sensor to be a second detection sensitivity lower than a first detection sensitivity set before the setting is changed, the second detection range being outward of the first detection range when viewed from the sensor, and
- in response to the measurement target being detected in the first detection range and the detected measurement target moving away from the sensor, changing the setting to change the detection sensitivity for the second detection range from the second detection sensitivity to the first detection sensitivity.
A detection method comprising:
- in response to a measurement target being detected in a first detection range that is part of a detection range in which the distance to the measurement target is detectable by a sensor that detects a distance to a measurement target, changing setting to cause a detection sensitivity for a second detection range in the detection range of the sensor to be a second detection sensitivity lower than a first detection sensitivity set before the setting is changed, the second detection range being outward of the first detection range when viewed from the sensor, and
- in response to the measurement target being detected in the first detection range and the detected measurement target moving away from the sensor, changing the setting to change the detection sensitivity for the second detection range from the second detection sensitivity to the first detection sensitivity.
