AI Technical Summary

Problems solved by technology

Since the pan / tilt adopts an open-loop control method, the monitoring center can control the rotation of the pan / tilt, but the direction of the surveillance camera cannot be obtained. When the function changes the angle, the monitoring center also cannot obtain the accurate monitoring direction of the monitoring camera, especially the real-time dynamic direction during the rotation of the camera
Since the dynamic angle of the monitoring camera and the direction information in the geographic coordinate system cannot be obtained accurately, the monitoring center cannot accurately determine the monitoring area of ​​the collected images, so it is impossible to accurately locate the monitoring target through image pattern recognition technology, which seriously restricts monitoring. The development and application of technology, especially the application in the field of dynamic target tracking and monitoring

Embodiment Construction

[0018] The monitoring camera with direction determination function is as figure 1 In the illustrated embodiment, include:

[0019] 1. The direction determination unit (101) adopts a three-axis acceleration sensor and a three-axis magnetic force sensor with fast response speed and high detection accuracy. The three-axis acceleration sensor selects the LIS3DH chip, which is characterized by a wide range of motion sensing and high sensitivity. The collected signals are digital signals, and the collected results are transmitted to the processor through I2C serial data communication. The three-axis magnetic sensor selects the HMC5883L chip, which has high precision, strong anti-interference ability, and high sensitivity. The collected signals are digital signals, and the collected results are transmitted to the processor through I2C serial data communication. Before use, it is necessary to measure the degree of offset of the axis of the above-mentioned three-axis acceleration sens...

Abstract

The invention discloses a monitoring camera with a direction determining function. The monitoring camera is not limited by a holder control manner, and can determine the direction dynamically in realtime by itself. The camera mainly comprises a direction determining unit, an angle detection unit, a data processing unit, an image collection unit, an image processing unit, a communication unit anda casing. The camera uses sensors of three different principles to obtain direction information of the camera, and is characterized by higher detection speed and precision, the real-time direction ofthe camera is monitored in real time, and has wide application prospects in the fields of dynamic target tracking and monitoring and image identification and positioning.

Description

technical field [0001] The invention relates to a monitoring camera with a direction determining function, in particular to the fields of sensor data collection and data processing. Background technique [0002] Surveillance cameras are the main video equipment of security surveillance systems. With the development of digital image processing technology and pattern recognition technology, the application range of surveillance cameras has been further expanded. Underground monitoring cameras in coal mines are also more widely used in the fields of automatic coal mining, personnel and equipment monitoring and positioning. Surveillance cameras are generally fixedly installed on the pan-tilt, and are controlled by the pan-tilt control system to change the angle, so as to realize image acquisition in different areas. Since the pan / tilt adopts an open-loop control method, the monitoring center can control the rotation of the pan / tilt, but the direction of the surveillance camera...
