New description: [New technology field] In particular, it refers to a new type of monitoring. There is a kind of monitor and tracking device. [Previous technology] Previously, most kinds of monitors were fixed-point shooting, but A field-limited loss is produced' so that a monitor that can be rotated back and forth can increase the field of view of the monitor's but the magnification of the aforementioned monitors cannot be adjusted, resulting in a small and ambiguous lack of intruder images. In addition, in the past, the video recorder of the monitor was turned on for a long time, and the video was recorded all day long for storage, which caused the problem of excessive video storage. Therefore, how to solve the current lack of the monitor is an urgent demand in the current market. [New content] Therefore, the object of the present invention is to provide a monitoring and tracking device for monitoring which can improve monitoring efficiency and quality. Therefore, the novel identification tracking device includes a monitoring unit, an identification tracking (four) unit and a video recorder, the monitoring unit includes an infrared sensor and a three-axis adjustable camera, and the infrared sensor senses Measuring the moving object and generating a power-on minus the camera generates an image signal, the identification tracking control unit analyzes the image signal of the camera and generates one of a tracking control signal and a shutdown signal, and the tracking control signal is sent to the monitoring unit to adjust the camera angle and Magnification, the recorder receives the power-on signal and the shutdown signal from the monitoring unit. The function of the novel is to use the identification tracking control unit to analyze the image signal 'and then control (4) the monitoring unit to track and enlarge the image of the invader, so that the visual image is more clear, and if the interference is determined, the shutdown signal is transmitted to: the video recorder' In order to avoid unnecessary video files and to save energy ο / [Embodiment] The foregoing and other technical contents of the present invention, the features and functions, will be clear in the following detailed description of a preferred embodiment of the reference drawings. Presentation. Referring to Figures 1 and 2, a preferred embodiment of the novel identification tracking device includes a monitoring unit, an identification tracking control unit 2, and a video recorder 3. The monitoring unit 1 includes an infrared sensor u, and a three-axis adjustable camera 12, the infrared sensor u senses a moving object and generates a power-on signal, the camera 12 generates an image signal, and the camera 12 is The three-axis adjustable viewfinder/machine 12' is left and right pan (pan), up and down oblique (t mountain) and zoomed in and out (zoom). The identification tracking control unit 2 analyzes the image signal of the camera 12 and generates one of a tracking control signal and a shutdown signal, and the tracking control signal is sent to the monitoring unit 1 to adjust the angle and magnification of the camera 12. The identification tracking control unit 2 analyzes the number of pixels of the image signal and the aspect ratio to identify whether the moving object is a human. If it is a human, a tracking control signal is generated to the monitoring unit, and if the interference is generated, a shutdown signal is generated to the video recorder. 3. The recorder 3 receives the power-on signal and the power-off signal from the monitoring unit. The method for using the identification tracking device of the present invention is as follows. First, after an intruding object enters the monitoring range of the monitoring unit i, the infrared sensor 11 senses dynamic movement of the invading object, and the infrared sensor 11 The power-on signal is generated to the video recorder 3, so that the video recorder 3 starts to store the video signal captured by the camera 12. The identification tracking control unit 2 analyzes the image signal to identify that the invading object is a human or other interference such as a dog or a dog. If it is only a general interference, the identification tracking control unit 2 generates a shutdown signal to the video recorder 3 to save The video recorder 3's video space saves energy. If the invading object is recognized as a person, a tracking control signal is generated to the camera 12, and an error value of the humanoid center and the center of the screen is obtained according to the image signal, thereby adjusting the left and right panning of the camera 12 and the up and down tilting. After the camera 12 locks the intruder, the identification tracking control unit further generates a tracking control signal to adjust the magnification of the camera 12 to capture a clearer image. It is further explained that the identification tracking control unit 2 uses the information such as the number of pixels and the aspect ratio of the image to identify the average number of pixels of the adult image as the interference object or the person's magnification. The average number of pixels larger than the image of the yak dog is the pixel threshold of the adult image and the yak dog image. When the identification tracking control unit 2 analyzes the number of pixels of the invading object image signal exceeding the pixel threshold, the invading object is recognized as a human. If it is lower than the pixel threshold, the invading object is identified as an interferer. The aspect ratio information is that the average aspect ratio of the adult image is greater than the average height of the cat and the dog: the aspect ratio threshold of the adult material and the image is set, and the identification tracking control unit 2 When the aspect ratio of the image signal of the invading object exceeds the aspect ratio threshold, the invading object is identified as the human being, and the opposite is recognized as the general interference. The novel type is a monitoring identification tracking device with human figure recognition, tracking lock, zooming K image, etc., and excludes interferences such as cats and dogs to avoid unnecessary video surveillance to save energy, and is controlled by tracking control signals. The photo (4) 12 (four) and the money invaders (four) image, effectively make the surveillance video signal clearer, it can indeed cost new purposes. It is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the scope of the present invention, that is, the simple equivalent change of the patent scope and the new description content of the present invention. And modifications are still within the scope of this new patent.
