Nomenclature of monitoring system-automatic high speed tracking fast ball

The automatic high-speed tracking dome is a combination of optics, electronics, machinery, information processing and network. It consists of cameras, power transmission, motion control devices, image analysis, recognition, compression and communication based on high-speed parallel processing. With video camera, position control, azimuth and lens preset, moving target detection, identification and tracking, flame and smoke detection alarm and other functions. When the moving target enters the field of view of the spherical camera, the high-speed DSP chip is used to calculate the difference between the previous image and the current image. When a certain value is reached, a certain part of the frame is determined to be a moving object, and then The dome camera automatically issues instructions to the dome camera head, and so on, so as to control the spherical camera to achieve continuous tracking of moving objects without the need for human operation or computer system support. LINE LOCK is a synchronization method that uses AC power to lock the camera's field synchronization pulse. When there is network wave interference caused by AC power in the image, set this switch to the line lock synchronization (LL) position to eliminate AC power interference.
