    摘要： A camera system including a camera and a gateway connected to the gateway through a channel is provided. The camera includes: a radio frequency (RF) module connected to the gateway through the channel, and configured to receive a beacon periodically sent from the gateway, the beacon including channel information about a next channel to which the channel is to be changed for connecting the camera and the gateway; and a controller configured to determine whether the beacon is received at the RF module, and change the channel to another channel based on at least one of: a predetermined order of a plurality of channels including the other channel; a status of receiving the beacon at the RF module; and a channel check response received from the gateway in response to a channel check request sent from the radio frequency module, the channel check response comprising channel information about one of the plurality of channels.

    摘要： Exemplary embodiments disclose a method of acquiring a horizontal distance between a camera and a target, which is a horizontal distance between a central point of an optical system of the camera and a ground landing point of the target. The method includes acquiring a relative target angle using an angle between a ground and a camera-target connection line which connects the central point of the optical system of the camera and the ground landing point of the target, acquiring a height of the camera using a height of the central point of the optical system of the camera on a basis of a vertical position of the ground landing point of the target, and setting a quotient of the height of the camera divided by a tangent value of the relative target angle as the horizontal distance between the camera and the target.

    摘要： A method of sampling feature points, an image matching method using the same, and an image matching processor are disclosed. The method of sampling feature points for image matching includes: dividing a first image into a plurality of regions corresponding to a number of feature points to be sampled; extracting a sampled feature point from each of the regions such that a distance between a sampled feature point of one region and a sampled feature point of another region satisfies a predetermined condition; and estimating a homography on the basis of the extracted sampled feature points and corresponding sampled feature points of a second image to be matched with the first image.

    摘要： A manufacturing process visualization apparatus is provided. The apparatus includes: at least one processor configured to implement: a data receiving unit which receives apparatus data from at least one production apparatus of a manufacturing process line processing a plurality of products; and a matching unit which extracts product record information about each of the products from the received apparatus data, classifies the extracted product record information as information corresponding to specific product flow properties of the manufacturing process line, generates product flow information indicating the specific product flow properties by using the classified product record information, and generates graphic process information about the manufacturing process line in which the product flow information about each product is represented in graphics; and a screen display which displays the generated graphic process pattern information on a screen.
