Abstract
An object distance measurement apparatus may include: a camera to capture an image of an area around a vehicle; a distance sensor to detect a distance from an object by scanning around the vehicle; and a distance measurement unit that detects a vehicle moving distance using vehicle information generated by operation of the vehicle, and measures the distance from the object in response to each of frames between scan periods of the distance sensor, among frames of the image, based on the vehicle moving distance and the location pixel coordinates of the object within the images before and after the vehicle moves.
Claims20
An object distance measurement apparatus comprising:
- a camera configured to capture an image of an area around a vehicle;
- a distance sensor configured to detect a distance from the vehicle to an object by scanning around the vehicle;
- and
- a distance measurement unit configured to:
- detect a vehicle moving distance based on vehicle information of the vehicle, and
- measure the distance from the object in response to each frame among frames of the captured image between first and second scan periods of the distance sensor, based on the vehicle moving distance which the vehicle moves in a period from the first scan period to the second scan period and location pixel coordinates of the object within captured images from the first scan period to the second scan period.
An object distance measurement method comprising:
- capturing, by a camera, an image of an area around a vehicle;
- sensing, by a distance sensor, a distance from an object to the vehicle by scanning around the vehicle;
- and
- detecting, by a distance measurement unit, a vehicle moving distance based on vehicle information of the vehicle, and measuring the distance from the object in response to each of frames between scan periods of the distance sensor, among frames of the captured image, based on the vehicle moving distance which the vehicle moves in a period from the first scan period to the second scan period and location pixel coordinates of the object within captured images from the first scan period to the second scan period.

- and
- a determination unit configured to:
- compare a camera frequency of the camera with a scan frequency of the distance sensor, and
- determine whether to interpolate the distance from the object for each frame of the frames of the image.
