Abstract
An apparatus and method of detecting a position of a light source are provided. The method includes: generating a top view image of a vehicle by using one or more cameras mounted on the vehicle; detecting a shadow area from the top view image by using an artificial intelligence model trained to recognize objects from a video or an image input; detecting a first area corresponding to an area of a shadow of the vehicle from the shadow area; detecting a direction of the light source based on the first area; and calculating an incidence angle at which light emitted from the light source is incident on the vehicle, based on the first area.
Claims13
A method of detecting a position of a light source, the method comprising:
- generating a top view image of a vehicle by using one or more cameras mounted on the vehicle;
- detecting a shadow area from the top view image by using an artificial intelligence model trained to recognize objects from a video or an image input;
- detecting a first area corresponding to an area of a shadow of the vehicle from the shadow area;
- detecting a direction of the light source based on the first area;
- and
- calculating an incidence angle at which light emitted from the light source is incident on the vehicle, based on the first area.
A method of detecting an intensity of a light source, the method comprising:
- generating a top view image of a vehicle by using one or more cameras mounted on the vehicle;
- detecting a shadow area from the top view image by using an artificial intelligence model trained to recognize objects from a video or an image input;
- calculating a first brightness that is an average brightness of the shadow area;
- calculating a second brightness that is an average brightness of remaining areas other than the shadow area in the top view image;
- and
- detecting the intensity of the light source using a difference between the first brightness and the second brightness.
A light source detection apparatus comprising:
- a sensor including an illuminance sensor and one or more cameras;
- a top view image generator configured to generate a top view image of a vehicle from a captured image from the one or more cameras;
- an object separator configured to detect a shadow area from the top view image by using an artificial intelligence model trained to recognize objects from a video or an image input;
- and
- a light source detector configured to detect a position and intensity of a light source based on the shadow area.
