Abstract
A method and system for recognizing a pedestrian's step is provided for a portable terminal. The portable terminal has an acquisition unit. In an image of a sequence of images acquired by the acquisition unit, an object is, in each case, detected which represents at least a part of a foot, a shoe, and/or a leg. The position of the object is determined in the respective image, and a pedestrian's step is recognized as a function of a position change of the object between at least two images of the sequence of images.
Claims17
A method of operating a portable terminal for recognizing a pedestrians step, the method comprising the acts of:
- acquiring, via an acquisition unit of the portable terminal operated by the pedestrian, a sequence of images of the pedestrian;
- detecting, in each image of the sequence of images, an object representing at least a part of a foot, a shoe, and/or a leg of the pedestrian;
- determining a position of the object in the respective image;
- recognizing a step of the pedestrian as a function of a position change of the object between at least two images of the sequence of images;
- and
- signaling to the pedestrian at least one of a current position and a determined route of the portable terminal based in part on the recognized step.
A system for recognizing a pedestrians step, comprising:
- a portable terminal operated by a pedestrian, wherein the portable terminal comprises:
- an image acquisition unit operatively configured to acquire a sequence of images;
- an image processing unit operatively configured to, in each case, detect an object in acquired images which represents at least part of a foot, a shoe, and/or a leg of the pedestrian;
- a control unit operatively configured to:
- determine a position of the object in a respective image,
- recognize a step of the pedestrian as a function of a position change of the object in at least two images of the sequence of images, and
- signal to the pedestrian at least one of a current position and a determined route of the portable terminal based in part on the recognized step.
