From the hardware to the Video Management Software
Benefits of the panoramic images
Using panoramic images has many benefits. Operators can observe a whole area from a single viewpoint. The Logipix Panorama cameras provide full coverage of large-scale areas without installing thousands of traditional security cameras. Operators could easily miss out on key information while scanning too many camera images. But to spot any suspicious activities more efficiently is more easy when watching a single high-resolution panoramic image.
Logipix panorama cameras
Logipix offers Panorama cameras in different constructions. Their common feature is that they deliver extraordinary image quality with hundreds of megapixels definition.
The Logipix Control Center provides a unique function for stitching the images of individual cameras together to create virtual panoramic views. This structure gives you the flexibility to tailor the camera setup to your own needs considering the necessary resolution and installation possibilities. For example, stitching the images of 16 pieces of Logipix ONE 20 MP cameras could create a powerful construction. It provides 320 MP panoramic images and 20 FPS imaging rate at full resolution. This huge amount of pixels allow for face recognition even at great distances.
Logipix has developed individual multi-sensor Panorama cameras that provide 200, 400 and 600 MP resolutions at a 20 FPS frame rate. The devices are capable of monitoring wide areas with a resolution that is high enough for recognizing any passenger’s face. They consist of ten, twenty or thirty pieces of specially constructed Logipix ONE 20 MP cameras, that are located in a massive, robust camera housing. It is possible to complete the camera enclosure with an automatic self-cleaning system and an active Peltier cooling system as well.
The cameras in all Logipix Panorama devices have synchronized imaging. This means that all the images are created at the very same time, therefore there will be no duplicate moving objects in the stitched images.
How to display
Logipix engineers created a versatile Video Management Software, the Logipix Control Center. It has numerous specially developed functions related to panoramic images. The software has been smartly designed to display the high-resolution panoramic images in a bandwidth-efficient way.
Working with and displaying such high resolution panoramic images is a real challenge for the network, and also for the computer. But Logipix has the solution for managing and displaying even 600 MP of visual information at the same time. The essence of Logipix Panoramic Technology is to store the panoramic images at full resolution on the NVR, but transmit and display only the necessary pixels. The 4K monitors can only display 8 MP of visual information, which is only a fragment of the full resolution. As there is no need to transmit the full size images the system sends resized, smaller images to be displayed on the monitors. When the operators want to see some detail and zoom in on images, the system is able to display these zoomed parts of the picture in a much higher resolution. Thus the Logipix Control Center always shows only the necessary pixels. The basis of this technology is the JPEG2000 compression standard and one of its main features, scalability. The JPEG2000 is the only image compression standard that was developed for managing 1000+ MP resolution images. The JPEG2000 standard provides all the necessary cropping and scaling functions that are needed for the efficient display of hundreds of megapixels. The NVR runs this algorithm without any performance reduction at 200 MP resolution level.
Versatile zooming functions
Logipix Control Center allows for different zooming possibilities, with Logi-Zoom. Although Logipix panoramic images are the stitched images of individual cameras, operators can work with them as if they were single images. They can zoom in on any parts of the panoramic image. They can also use and move around one or even more zoom windows at the same time. In these windows, the chosen parts of the panoramic image are displayed in high resolution. Using this function it is possible to track individuals in the zoom windows and observe the whole currently monitored area.
The best image quality
In the Logipix system, image processing algorithms are distributed among the camera, the video recorder and the displaying software. To display high-resolution panoramic images, multiple color, brightness and geometrical transformations have to be be performed.
The Logipix Control Center software fully utilizes the processing performance of modern GPUs. Using the GPU, Logipix can provide provide an accurate image stitching technology and effective image enhancement functions.
Logipix panorama and PTZ cameras working together
Logipix developed a worldwide unique function allowing PTZ cameras to be assigned to the panorama cameras. This way PTZs can work together with the panorama devices. The PTZ can be controlled on the panoramic images by selecting the area of interest. Based on common measuring points the PTZ camera can accurately find the selected image area. Operators can easily track suspicious activities utilizing the user-friendly control functions of the PTZs. Using 6 MP or Long Range PTZ cameras they can get minute details of the targets even if they are kilometers away.
Logipix PiP camera function
Logipix developed the PPM expansion function that can be very useful in various application fields. There are always priority areas within a monitored environment that should be observed with different parameters. The PPM expansion function allows the observation of such areas at a higher PPM value. Meaning, that these certain areas can be monitored in much higher resolution in the single panoramic image.
Logipix ePTZ function
LOGIPIX ePTZ works as an automatic zoom function. Areas can be defined within the panoramic image and for configured trigger events the defined areas appear on the monitor profiles in special zoom windows.
Safe policeman feature
There could be many dangerous situations when a policeman or a security guard needs extra help to get a fuller picture of the situation he is involved in. Logipix developed a smart feature that saves valuable time and provides extremely useful visual information. In these kinds of situations the guard or the policeman on the spot works together with the operator. They press a panic button that triggers an event in the Logipix Control Center. The software receives the GPS coordinates of the panic button and immediately displays every relevant panoramic and single images on the Video Monitor. Furthermore, the system automatically turns every nearby PTZ cameras on the target. As the operator, thanks to the high resolution images, can see much more than the person in trouble he can inform them what they should do, and where the threats exactly are. When the situation turns too dangerous the operator can tell where the guard or the policeman should hide or how they can escape.
