Abstract:
Disclosed is a method for detecting the existence of a part by analyzing an image obtained by photographing a part of a chassis. The method comprises a step of extracting a first image sample in which a part exists, a second image sample in which the part does not exist, and a third image sample which is irrelevant to the existence of the part; a step of learning how to detect the part from the image using the extracted first, second, and third samples; and a step of determining the existence of the part learned in a predefined interest section of the image, obtained by photographing a part of the chassis, based on the learning results.
Abstract:
The specification discloses a monitoring apparatus using a portable terminal. According to the present invention, peripheral environment information provided from a portable terminal, which collects and sends non-static peripheral environment information, is received via a network and displayed on screens of a plurality of customer terminals by using user interface (UI); and a spacing distance between a monitoring server and the portable terminal is maintained at a sufficient level. Also, a control signal for driving a motor on a pan and tilt mount is generated and transmitted in order to track a moving image by extracting stable motion information from the collected non-static peripheral environment information, such that the portable terminal is easily controlled.
Abstract:
PURPOSE: An image detection method and a device thereof using a dual camera are provided to continuously trace a moving object by converting a coordinate value of a moving object detected in a fixed type camera into a coordinate value of a movable camera. CONSTITUTION: A monitoring region matching unit (110) extracts respective feature points from a photographed image of a fixed camera and a movable camera while controlling an angle of the movable camera. The monitoring region matching unit designates a reference location of the movable camera with respect to the fixed camera through a matching process between the extracted feature points. A coordinate conversion unit (120) converts an image coordinate of a moving object detected by the fixed camera into an image coordinate of the movable camera. A camera control unit (130) controls at least one of a pan angle, a tilt angle and a zoom magnification ratio to trace the moving object using the converted coordinate value.

PURPOSE: A vision based part curvature estimating method and an apparatus thereof are provided to extract an outline from a photographed image about a part having a curved surface and to estimate central point coordinates about a virtual circle having the curved surface as an arc using arbitrary coordinates of the outline corresponding to the curved surface, thereby accurately estimating an actual curvature value about the curved surface. CONSTITUTION: A part curvature estimating apparatus obtains a photographed image about a part having a curved surface (S410). The part curvature estimating apparatus extracts an outline of the part from the photographed image (S420). The part curvature estimating apparatus estimates central point coordinates about a virtual circle having the curved surface as an arc using arbitrary coordinates of the outline corresponding to the curved surface (S430). The part curvature estimating apparatus estimates curvature of the curved surface using the arbitrary coordinates and the central point coordinates (S440).
