US 10,122,921 B2 · Apparatus and method for automatically recognizing object by using low-speed camera in dual photographing mode

Abstract

Provided is an apparatus and method for automatically recognizing an object by using a low-speed camera in a dual photographing mode, in which the apparatus includes an image acquirer and an image information analyzer. In the present disclosure, without using a separate motion sensor a movement state of a specific object during sports activities may be automatically recognized by using a successive photographing function of a low-speed camera in a dual photographing mode. Further, once an object starts moving, high-speed images in a multiple exposure mode may be automatically captured by using a high-speed photographing function of the low-speed camera in a dual photographing mode without using an expensive high-speed camera, and based on the captured images, movement information, including a movement speed and direction of the sports ball, the force and axis of rotation of the ball, and the like, is automatically analyzed to generate object movement information.

Dependent claims

An apparatus for automatically recognizing an object by using a low-speed camera in a dual photographing mode, the apparatus comprising:

an image acquirer configured to acquire successive images in a single exposure mode and high-speed images in a multiple exposure mode by using two low-speed cameras capable of performing successive photographing and high-speed photographing operations;
and
an image information analyzer configured to generate object movement information by analyzing the acquired successive images to determine a movement state of the object, and by analyzing successive images and high-speed images acquired by controlling photographing operations of the two low-speed cameras based on the determination,
wherein the image information analyzer further comprises:
an object movement information generator configured to determine the movement state of the object to be a state of waiting for movement in response to a determination that the object has yet to start movement, and generate object movement information in response to a determination that the object has started movement.
