1. Automatic identification (video analysis) technology
The automatic recognition function of high-speed dome is still in its infancy at home and abroad, and there is still a long process before it is mature. At this stage, the function of fast and automatic tracking of multiple targets and night vision function cannot meet the requirements. The automatic tracking function of the high-speed ball at the front end may be just a selling point in public security monitoring. The practical value has not yet been reflected. The real automatic tracking is achieved through the back end, and many manufacturers are now trying. If you are indoors, the error rate will be smaller, but if you are outdoors, the error rate will be relatively high due to too much environmental changes. Under normal circumstances, the software is used for behavior analysis in the back-end after the image is collected. This method is more effective than direct analysis in the front-end. Nowadays, the development of face recognition technology is relatively fast. If the face recognition technology can be applied to the automatic tracking system of the dome camera, it should be able to realize the tracking function.
Video intelligent analysis is the main technical hotspot in recent years and in the future, and more manufacturers will invest in research and development. In summary, high-speed dome video intelligent analysis will mainly have the following features:
Automatic tracking of targets: Automatically warn when someone moves or abnormal objects appear in the controlled channel, and start intelligent tracking. According to the setting, start recording or snapshot, start peripheral lights and alarm bells, etc.;
Motion detection and tracking: When a certain area is set as a motion detection area on the monitoring screen, intelligent tracking will be automatically activated when an active object illegally invades the area, and can start recording or capturing according to the setting, and activate the surrounding lights, Alarm bell, etc.;
Alarm linkage tracking: When an alarm occurs in a certain area of the system, the related high-speed ball will automatically rotate to the alarm point to start tracking, and can start video recording or capture according to the setting and activate the surrounding lights, alarm bells, etc.;
Timing cruise: Smart cruise schedule can be set for a ball, and the high-speed ball will automatically turn to the set preset position before the set time is reached to start the cruise;
Intelligent cruise: You can set a ball to perform round-trip detection in a certain key area in accordance with preset positions and preset focus requirements. The user can arbitrarily arrange the key monitoring area, and can be set to automatically switch to intelligent tracking when a target appears in the intelligent cruise state;
Manual tracking: The operator can select any high-speed dome monitor screen, click on a person or object on the screen, the high-speed dome will automatically rotate the pan/tilt to adjust the angle of view and focus, so that the alert target is in the center of the monitor screen , It is convenient for management personnel to view and record in real time.
2. Intelligent control technology
At present, the application of intelligence in high-speed domes has become increasingly widespread. For example, some high-speed domes have the function of detecting the internal temperature and humidity of the dome at any time, automatically starting the internal heating and cooling equipment, intelligent monitoring the fan rotation status, intelligent identification system protocol functions, etc. Wait.
With the continuous improvement of chip computing power and the emergence of many new algorithms, the expression of intelligent judgment on high-speed domes will become more and more extensive and more applicable, which will also enable high-speed domes to perform more effective functions in applications, and even In remote areas, solar-powered high-speed domes are also expected to have a certain demand.
