Abstract
An object tracking method and apparatus are provided. The object tracking method includes detecting a target object in a first-type input image that is based on light in a first wavelength band, tracking the target object in the first-type input image based on detection information of the target object, measuring a reliability of the first-type input image by comparing the first-type image to an image in a database, comparing the reliability of the first-type input image to a threshold, and tracking the target object in a second-type input image that is based on light in a second wavelength band.
Claims19
A heads-up display (HUD) device comprising:
- a memory storing instructions;
- and
- a processor, which, upon executing the instructions is configured to:
- track user eyes in a first modality that is based on light in a first wavelength band;
- switch a modality of tracking the user eyes from the first modality to a second modality, the second modality is based on light in a second wavelength band, different from the first wavelength band;
- and
- track the user eyes in the second modality,
- wherein the processor further configured to:
- determine a detection box corresponding to the user eyes in a first frame of an input image by scanning entire area of the first frame;
- track the user eyes in a second frame of the input image by using information on the detection box without scanning entire area of the second frame.
A heads-up display (HUD) device comprising:
- a memory storing instructions;
- and
- a processor, which, upon executing the instructions is configured to:
- determine whether user eyes can be detected in a first modality that is based on light in a first wavelength band;
- if it is determined that the user eyes can be detected in the first modality:
- track the user eyes using a first-type input image of the first modality based on detection information of the user eyes;
- switch a modality of tracking the user eyes from the first modality to a second modality, the second modality is based on light in a second wavelength band, different from the first wavelength band;
- and
- if it is determined that the user eyes cannot be detected in the first modality:
- detect a target object in the second modality.
An eye tracking apparatus comprising:
- a memory storing instructions;
- and
- a processor, which, upon executing the instructions is configured to:
- track user eyes in a first modality that is based on light in a first wavelength band;
- switch a modality of tracking the user eyes from the first modality to a second modality, the second modality is based on light in a second wavelength band, different from the first wavelength band;
- and
- track the user eyes in the second modality,
- wherein the processor is further configured to:
- determine a detection box corresponding to the user eyes in a first frame of an input image by scanning entire area of the first frame;
- and
- track the user eyes in a second frame of the input image by using information on the detection box without scanning entire area of the second frame.
