Abstract
In accordance with an aspect of disclosure, the vehicle includes a first sensor configured to measure a distance to an object; a second sensor configured to measure a temperature of the object; a camera configured to acquire an image of the object; and a controller configured to activate the second sensor when the distance to the object measured by the first sensor satisfies the condition for performing heat detection, and activate the camera when the temperature of the object measured by the second sensor satisfies a condition for performing facial recognition.
Claims20
A vehicle, comprising:
- a first sensor configured to measure a distance to an object;
- a second sensor configured to measure a temperature of the object;
- a camera configured to acquire an image of the object;
- and
- a controller configured to:
- identify a first distance to the object measured at a first time point by the first sensor and a second distance to the object measured at a second time point by the first sensor,
- when the second distance is shorter than the first distance and a value obtained by subtracting the second distance from the first distance is equal to or greater than a preset value, determine that a condition for performing heat detection is satisfied,
- when the value obtained by subtracting the second distance from the first distance is less than the preset value, identify a change in distance to the object measured by the first sensor between the first time point and the second time point,
- when the identified change in distance to the object changes from a decreasing state to an increasing state, determine that the condition for performing heat detection is not satisfied,
- activate the second sensor in response to determining that the condition for performing heat detection is satisfied,
- maintain the second sensor to be turned off in response to determining that the condition for performing heat detection is not satisfied, and
- activate the camera when the temperature of the object measured by the activated second sensor satisfies a condition for performing facial recognition.
A controlling method of a vehicle, comprising:
- identifying a first distance to the object measured at a first time point by a first sensor and a second distance to the object measured at a second time point by the first sensor;
- when the second distance is shorter than the first distance and a value obtained by subtracting the second distance from the first distance is equal to or greater than a preset value, determining, by a controller, that a condition for performing heat detection is satisfied;
- when the value obtained by subtracting the second distance from the first distance is less than the preset value, identifying, by the controller, a change in distance to the object measured by the first sensor between the first time point and the second time point;
- when the identified change in distance to the object changes from a decreasing state to an increasing state, determining, by the controller, that the condition for performing heat detection is not satisfied;
- maintaining, by the controller, a second sensor to be turned off in response to determining that the condition for performing heat detection is not satisfied;
- activating, by the controller, the second sensor in response to determining that the condition for performing heat detection is satisfied;
- measuring a temperature of the object by the activated second sensor;
- and
- activating, by the controller, a camera when the temperature of the object satisfies a condition for performing facial recognition.
