What is an omni-directional camera?

If I remember correctly, it's a 360-degree fisheye lens. The image on the monitor is distorted without processing. Software should be distributed in places where cameras are sold, similar to monitoring software. He can convert the picture on the 360-degree fisheye lens into four pictures, just like installing cameras in four directions, usually installed on the ceiling. If you like, it can also be installed on the ground or on the wall.

360-degree panoramic monitoring system

With the continuous development of high-tech technology, people's requirements for monitoring and collecting video information are getting higher and higher. In order to meet people's growing demand for video information, 360-degree panoramic monitoring systems, which can be used in industry, commerce, forestry, military, government, Internet and private houses, have gradually entered the China market.

According to the market demand, Creative Video Technology Company uses high-definition network cameras to form a 360-degree panoramic monitoring system. The system has a unique 360-degree synchronous observation, all people and activities can be seen at a glance, no unexpected events will be missed or missed, and there are no blind spots and dead corners in the real panoramic range, which can not only see the overall situation but also see through the details; Users can directly see the undistorted 360-degree video without using complicated "expansion software" or splicing multiple images; Save the time of browsing the happened events and improve the speed of target confirmation. Its appearance marks a revolution in intelligent monitoring.

First, the characteristics of 360-degree panoramic monitoring system

1, true wide-angle camera

The panorama camera, which is 360 degrees horizontally and 180 degrees vertically, subverts the previous concept of wide-angle camera. For 360-degree products,

Video surveillance has no dead ends.

2. The spherical image can be converted into a normal plane view.

The image taken by the fisheye lens can be converted into a normal plane view suitable for human eyes after the correction of the camera's internal software and the expansion of the drawing.

3. Save system cost in various ways.

Compared with the traditional camera video monitoring system, the panoramic monitoring system can save you investment in four aspects.

(1) Save hardware resources: The panoramic smart ball has 360-degree full-time panoramic monitoring capability, and there is no need to install multiple cameras to cover the entire monitoring area, thus saving considerable hardware investment;

(2) Save labor operation cost: The system has the ability of automatic target monitoring, panoramic tracking and alarm, which greatly reduces the number of security personnel and the technical level requirements for operators, reduces labor operation cost and greatly reduces their labor intensity;

(3) Saving additional controller cost: The system has digital signal processing function, and there is no need to configure additional control host, thus saving controller cost;

(4) Saving the cost of supporting equipment: Traditional cameras can't achieve 360-degree panoramic monitoring because of their small field of view, so they must rely on installing multiple cameras to achieve the coverage of the monitoring area. Not only does the cost of cameras and their installation cost increase greatly, but also the cost of video recording, display and other equipment increases with the increase of the number of cameras. Panoramic monitoring system can save the cost of supporting equipment, reduce the difficulty of construction wiring and save the subsequent maintenance costs.

4. You can access the existing video monitoring system.

The 360-degree HD webcam can be seamlessly connected to the existing monitoring system, with good scalability.

5. Other characteristics

In addition to the above functions, the unique 360-degree panoramic virtual PTZ technology can experience operations such as zooming in/out and rotating when playing back images, which can completely replace the motor-driven pan/tilt control system in traditional high-speed ball machines. With the technical foundation of virtual PTZ, on the one hand, it will be easier to realize virtual reality; On the other hand, it will reduce mechanical and motor parts, reduce the power consumption and heat generation of equipment to a greater extent, reduce the friction loss of equipment, and prolong the service life of equipment and systems.

Therefore, using 360-degree panoramic camera, the video monitoring system in narrow space has a brand-new scheme, which can solve many problems such as sight distance, angle of view, installation and cost control.

Second, the composition of 360-degree panoramic monitoring system

1, panoramic HD network camera-basler HD network camera BIP- 1300c and BIP- 1300c-dn.

Basler BIP- 1300c and BIP- 1300c-dn adopt Sony EXview HAD progressive scanning CCD photosensitive chip, and the resolution can reach 1.2 million pixels (1280*960), providing more perfect image quality and higher transmission frame rate, even at low rates. These unique advantages of Basler network camera make it widely used in the field of video surveillance.

Functions and advantages

◆ High definition CCD with progressive scanning.

The common interlaced scanning system will make the dynamic image jagged or blurred due to the processing time difference. Basler network camera adopts high-definition CCD image sensitive chip with progressive scanning, which not only improves the vertical resolution, but also avoids visual artifacts, and the generated images are more vivid and clear.

◆ Multiple coding and multiple video streams

Only the Basler network camera can provide all-round video compression technologies, including MJPEG, MPEG-4 or H.264 that meet the standards. The Basler webcam also supports multiple video streams. Users can use multiple MJPEG streams for high-quality monitoring, and at the same time, they can open an MPEG-4 or H.264 to obtain high-frame video recording.

◆ Region of Interest Function (AOI)

The unique region of interest (AOI) function allows users to set multiple regions of interest in the original view, and display more image details with higher accuracy. Users can encode and transmit these selected areas separately, thus transmitting multiple image details, saving storage space, improving equipment utilization and reducing bandwidth requirements.

◆ Real day and night type

By automatically shrinking the infrared filter, the Basler network camera can provide high-quality color mode during the day, high-sensitivity black-and-white mode at night and in low light environment, and even provide tiny details in dark environment.

◆ Motion detection &; Alarm buffer function

Users can use 32*24 definable field arrays to generate up to 5 different masks. Motion detection can be combined with time monitoring and alarm management functions. The alarm buffer function can save the video images recorded during the alarm on the memory through the transmission line to prevent the image data from being lost, even if the image transmission is delayed due to broadband limitation or network traffic problems.

◆ Appearance and three-dimensional design

Minimum webcam: 89.8mm*29mm*44mm, Full Metal Jacket. This product is more flexible and convenient to install.

Excellent product quality

In order to ensure consistently excellent product quality, basler has adopted a variety of advanced testing procedures in the manufacture of each camera, striving to meet the highest requirements of customers.

Generally speaking, the shorter the focal length, the larger the viewing angle and the larger the viewing angle, and the stronger the deformation caused by the optical principle. In order to achieve a large viewing angle of 360 degrees horizontally and 180 degrees vertically, the fisheye lens allows barrel distortion to exist reasonably, and all other scenes that should be horizontal or vertical have changed accordingly except the scene in the center of the picture. In order to transform the distorted image into a normal image suitable for human eyes, it is necessary to transform the coordinates of the image and correct the image through software.

Third, the 360-degree panoramic monitoring system application case

360-degree panoramic monitoring system can be widely used in building halls, entrances and exits, elevators, conference rooms, restaurants, parking lots, factories and other minutes.

1, Application in Bus Carriage

2, a company meeting room application

3. Application of road monitoring at intersections.

As shown in the above example, 360-degree panorama camera can capture the image information of the environment around the bottom of the eye. Can be used freely in a narrow space, and can eliminate dead corners and blind spots. Regardless of the overall size, it takes seven wide-angle cameras {(360 ÷ 75 ≈ 5)+(18075 ≈ 2)} to realize a 360-degree "panoramic" camera field of view according to the existing 2.8mm (75 degrees) wide-angle camera combination in the market, so the panoramic monitoring system greatly reduces the system.

Four. conclusion

360-degree panorama can truly and quickly express all the image information of the scene within 360 degrees, and can bring the viewer an immersive feeling. In many application scenarios, the advantages are obvious. In addition to monitoring the industry, it can also play a huge role in product display, video teaching, audio-visual entertainment, virtual reality and so on. I believe that in the near future, this image technology will be applied to various industries.
