Embodiment 1

[0035] Embodiment 1 is a monitoring device, at first, with reference to figure 1 As described above, an intelligent panoramic three-dimensional monitoring system based on a fisheye camera 1 includes a casing 10 and a fisheye camera 1 .

[0036] The housing 10 is provided with an inertial sensor, a core processing module 9, and a wireless transmission module. The inertial sensor includes the three-axis gyro module 3, the magnetometer module 4, and the three-axis accelerometer module 5. The inertial sensor is fixed inside the housing 10, and there is a first relative pose relationship between the inertial sensor module and the fisheye camera 1,

[0037] The three-axis gyro module 3 is configured with a first absolute pose representing the position of the inertial sensor;

[0038] The magnetometer module 4 is used to determine the first direction relationship of the inertial sensor on the horizontal plane of the earth coordinate system;

[0039] The three-axis accelerometer mod...

Embodiment 2

[0065] Embodiment 2 is applied to be installed on both sides of the expressway to survey the traffic conditions in the area. The system of the present invention is fixed on the street lamps on both sides of the expressway, and the fisheye camera is calibrated. Take the video image of the expressway and send it back to the traffic information processing center in real time through the wireless transmission module. The transmitted video images are processed and analyzed by the patented method. Output the processing results to realize the purpose of road traffic survey and monitoring, traffic individual identification, tracking and behavior analysis.

Embodiment 3

[0066] Embodiment 3 is applied to the indicator lights installed on both sides of the airport runway to monitor the take-off and landing of various aircraft in the airport area, the intrusion of abnormal targets on the airport runway, and the like. The system of the present invention is fixed on the indicator lights on both sides of the airport runway or other suitable places, and the fisheye camera is calibrated. Take video images of the airport area and send them back to the traffic information processing center in real time through the wireless transmission module. Process and analyze the transmitted video images. Output the processing results to realize the purpose of surveying and monitoring the take-off and landing area of ​​the airport, identifying, tracking and behavior analysis of various aircraft, personnel, vehicles and other related individuals.

[0067] refer to Figure 4 As shown, the implementation process of the monitoring system of the present invention is i...

Abstract

The invention relates to a monitoring device and monitoring system based on a fish-eye lens camera. A system main body is composed of a plurality of independent monitoring devices and a special calibrating trolley. Different from a conventional image-based three-dimensional monitoring system which is mounted needs to be in complicated calibrating modes separately, the monitoring device provided by the invention is only mounted and fixed on a common lamp tube or an airport runway, so that the convenience and practicality of the system are greatly improved. Besides acquiring common traffic static data or monitoring data of an airport, the system also can survey and monitor the road traffic or a landing region of the airport, and achieves the purposes of identifying, tracking and three-dimensionally positioning traffic individuals, analyzing behaviors and the like.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an intelligent panoramic three-dimensional position monitoring device and a monitoring system based on a fisheye camera. Background technique [0002] With the development of information technology, data communication transmission technology, electronic sensing technology, computer technology and other technologies, intelligent transportation systems are increasingly valued by various countries.
