Abstract: Disclosed is an image analysis apparatus for analyzing a camera image. The image analysis apparatus for analyzing a camera image segments an input fisheye camera image into segmented images with a preset size field of view and superimposes the segmented images so that some regions overlap, performs dewarping on each of the segmented images, then combines the segmented images on which the dewarping is performed using a preset combination method, generates an analysis image, and detects objects included in the analysis image. In this case, the image analysis apparatus removes a result recognized as a duplicate from a detection result of the object by post-processing.

Abstract: Disclosed is a bottom housing for a dome camera having high heat dissipation efficiency. The bottom housing for a dome camera has an improved structure in which a bottom housing sub-plate made of metal is coupled to a bottom housing main body made of plastic, thereby achieving efficient heat dissipation and waterproofness and suppressing increase in manufacturing cost.

Abstract: A video security system with improved network response speed using pre-authentication information, which is capable of improving a network response speed by simplifying handshaking for securely exchanging authentication information and an encryption key in a process of starting communication between a client terminal and a server using pre-authentication information that is valid only for the client terminal, is provided.

Abstract: A three-way parking control camera apparatus with a parking space displaying function is provided and allows occupants in a vehicle entering from a front side of a parking passage to easily recognize the direction of parking areas on both sides of the parking passage where there is an empty parking space.

Abstract: Disclosed is a technology related to a video surveillance system using a camera capable of a pan-tilt-zoom operation. The video surveillance system includes a pan-tilt-zoom camera for photographing a surveillance region, and a display device for outputting an image of the pan-tilt-zoom camera. The pan-tilt-zoom camera provides a fisheye image representing an entire surveillance region onto a first region of the display device, calculates driving parameters of the pan-tilt-zoom camera on the basis of location information of a portion selected from the fisheye image, moves the pan-tilt-zoom camera to a location of the selected portion according to the driving parameters, and provides a monitoring image of the selected portion photographed by the pan-tilt-zoom camera onto a second region of the display device. According to the present invention, the pan-tilt-zoom camera is allowed to be intuitively and rapidly controlled using the fisheye image and to rapidly generate a fisheye image.

Abstract: Provided is a video playback system based on approval of a playback approver. A decryption key that can decrypt an encrypted and stored recorded video is generated only when video playback is approved by a playback approver using an appointed playback approval method and transmitted to the video recording device so that it is possible to prevent leakage of the recorded video with sensitive personal information.

Abstract: Provided is a video search interfacing apparatus for efficiently searching for a plurality of recorded video channels by generating a search history by selecting cameras in a time series manner according to a traffic line of an object of interest on a map on which physical positions of a plurality or cameras are visually arranged, thereby searching for a plurality of recorded video channels more intuitively.

Abstract: Disclosed is a technique for a railway disaster monitoring system for monitoring a foreign matter on a railway, which includes a camera and an image processing unit that receives a railway image captured by the camera. The image processing unit includes a segmented image acquisition unit that obtains a plurality of segmented images including a rail from the railway image received from the camera and scales the segmented images to obtain segmented image blocks of a predetermined size, and a segmented image determination unit which includes deep neural network (DNN) discriminators trained with deep learning neural networks and inputs the segmented image blocks to the DNN discriminators to determine whether the railway is in a normal state in which there is no foreign matter on the railway except a train passing by. Using the segmented images, a foreign matter on a railway can be rapidly and easily determined using a deep learning neural network even with a small number of resources.

Abstract: Provided is a monitoring system and a method of controlling a panning-tilt zoom (PTZ) camera by using a fisheye camera when the fisheye camera and the PTZ camera are adjacently installed. The method includes selecting a region of interest (ROI) in an entire surveillance-target area image captured by the fisheye camera and adjusting a panning angle P and a tilting angle T of the PTZ camera to acquire an accurate image of the selected ROI.

Abstract: An IP camera security system allowing secure encryption information to be transmitted is provided that is implemented such that an encryption key and an encryption method are managed not by an IP camera and a client terminal vulnerable to security but by an image storage device having robust security so as to further secure the network segment security.
