Automatic tracking
Automatic tracking is the process of automatically following the target and performing coordinate observation and measurement through the follow-up system according to certain characteristics of the signal.
Automatic tracking is a system that continuously tracks and measures the parameters of a moving target trajectory. The goal of automatic tracking is the movement of vehicles, ships, airplanes, missiles, and artificial satellites with a certain speed and acceleration. Automatic tracking can provide spatial positioning, posture, structural behavior and performance of moving targets. It is a multi-functional and high-accuracy tracking and measurement method for moving targets. Automatic tracking consists of position sensors, signal processing systems, servo systems, and tracking frames. .
System composition and classification
The automatic tracking system is composed of position sensors, signal processing systems, servo systems and tracking frames. The automatic tracking system is classified according to the different types of sensors: radio-tracking systems that use electromagnetic wave characteristics; optical (opto-electric) tracking that uses light-wave characteristics. system.
Application of Automatic Tracking Technology in Video Surveillance
At present, the detection equipment used in the detection and alarm system is mainly to detect changes in the physical quantity and status of the environment. This detection method does not inherently have the ability to detect targets. Therefore, the problem of false alarms has always plagued security systems. The use of multiple detector elements, multi-technical composite detection, and intelligent data analysis has greatly improved the performance and functionality of the detector and reduced the false alarm rate. However, this does not fundamentally solve the problem.
The video surveillance technology observes the on-site objectives and directly identifies the features of the target. This is an effective detection method and is a detection method that does not require rechecking or integration with the review.
In the design of real security projects, we must first consider the alarm, the so-called alarm priority, and the video surveillance as an auxiliary system, because any check-in operator in the unknown state, can not pay attention to the picture for a long time. In order to reduce the influence of artificial fatigue factors and ensure reliable operation of the system, alarms are usually given priority.
When the moving target enters the camera's field of view, a high-speed DSP chip is used to perform differential calculations on the previous frame of the image and the current image. When a certain value is reached, a particular part of a frame is determined as a moving object, and then The ball machine automatically issues instructions to the ball head, so that it cycles back and forth, thus controlling the ball camera to achieve continuous tracking of moving objects without human operation, and does not require the support of computer systems!
Auto Track's Auto Dome is a new type of camera that can be programmed to perform "smart patrols," ie scanning an area according to a pre-programmed patrol route, and when a motion is detected, the camera will stop Continue the patrol procedure, zoom in on the target image, and track the target to record the motion and send an alarm. These actions do not require the help of the operator, allowing the operator to handle the alarm or take other actions.
Automatic Tracking Machine Introduction â— Features:
Has a tracking function for capturing moving targets in a complex background. That is, there is no need to add any hardware or software. As long as the moving target is in the field of view, the dome camera can automatically capture and track the moving target, realizing a 24-hour unattended security guard on the spot! Support the alarm to find the point and start the tracking: The track ball and the alarm device can be connected through the 485 control line. Once an alarm signal appears, the track ball will be automatically transferred to the specified position and then start the tracking.
The technique of automatically returning a preset point: that is, after the ball camera finishes the whole process of tracking (tracking is completed after the target leaves the field of view of the camera), it can return to the point where tracking started within the user's specified time!
With multi-point preset positioning, memory, auto-cruise, curve trace scanning, local scanning (90 ° or 180 ° or 360 °) and other functions. You can arbitrarily position, but also omni-preset cruise!
Built-in super dynamic camera; built-in high-speed preset PTZ and decoder; communication protocol open, applicable to a variety of control host; imported stepper motor, smooth and reliable operation; 256 presets and automatic cruise, multi-point inspection function; With lightning protection, anti-overvoltage, anti-static, anti-electromagnetic interference and other functions. Compatible with PELCO-D, PELCO-P and other domestic and foreign protocols, baud rate is adjustable.
Automatic Tracking Dome Camera Improves Monitoring Performance of Security Technology
1. The monitoring system of the ball camera with automatic tracking will be active monitoring. Most monitoring systems are reactive. The method used by this monitoring system is to check the video tape or hard disk afterwards. Passive monitoring. For automatically tracking ball cameras, when a motion is detected, the camera sends out a signal to instruct the camera to actively track the target. At the same time, the recording frequency of the video is increased and an alarm is issued to the operator. After the intruder is locked, the operator is automatically tracked. It is an active monitoring method to immediately study the images entering the scene and take action to stop the crime.
2, the operator's work becomes easier and more efficient Under normal circumstances, an operator to monitor multiple screens, while controlling the camera's joystick, and with the automatic tracking of the ball camera, the camera itself to monitor, once Discover motion. It automates zooming, tracking, recording, and alarming so that operators don't need to stare at the screen to complete other tasks.
