Multicamera tracking and high resolution 3D stereo vision

Country of Origin: Croatia
Reference Number: TOHR20190301001
Publication Date: 5 March 2019

Summary

A Croatian company has developed an innovative method of tracking objects in 3D multi-camera environment. The method includes a panoramic camera, PTZ (Pan Tilt Zoom) full body camera, auto zoom and auto-tracking of people over a wide area. They also feature high-resolution 3D stereo images. The 3D position is marked for each pixel in the stereo image for easy, automated and fast 3D mapping. Looking to sign a joint venture, technical cooperation or commercial agreement with technical assistance.

Description

This Croatian engineering company is specialized in 3D object tracking in single and multicamera environment setup and high-resolution stereo imaging. They have developed several tracking and surveillance solutions: camera stage tracking system, automated video surveillance and stadiums & smart city surveillance for instant situation awareness.
The SME has a great international experience in entertainment industry with their solution for visual tracking using a single camera. That system has become industry standard.

The company has recently developed a new method of tracking objects through several video cameras in large areas. It also includes a method of tracking objects in real time with PTZ (Pan Tilt Zoom) cameras that allow the development of automated video surveillance systems.
Multicamera environment allows the use of various type of cameras in one surveillance system: panoramic, PTZ (Pan Tilt Zoom) and thermo cameras.
Panoramic camera will detect any person or any vehicle in a supervised area. But it will not detect persons face or a vehicle licence plate, therefore PTZ cameras are used. Based on the image from panoramic camera, PTZ camera is directed to full-body zoom and full vehicle zoom.
Surveillance systems for large high security public areas will have several PTZ cameras. Also security officer is able to direct all PTZ cameras on one person or selected area for full situation awareness.
Tracking a single person in real time using several PTZ cameras is also a feature of this method. Tracking can be manually or automatic by using standard algorithms of object tracking in video stream. This method also supports multi objects in real time tracking.

All these features of multicamera system enables the development of automated video surveillance system.
Panoramic cameras are used for large area surveillance. Any movement detection will automatically direct the thermo and PTZ cameras for close imaging and zooming on the subject.
For example, relevant person on a city square can be zoomed from any direction for the face detection and recognition.
Also the system can have dislocated clients/users such as city surveillance, police or traffic surveillance who could use the system for their needs.
This method enables development of automatic surveillance systems. System will detect movement, use the PTZ cameras for zooming and use thermal cameras for imaging. The system activate tracking, calculate object height and width and if criteria meet, it would send a alarm message and video stream to remote location or surveillance center.
Also automated positioning of zoom and thermal cameras can be used in automated fire detection systems. Again, panoramic camera will survey wide area and if disturbance in pixels are detected, system will automatically direct long range thermal imaging camera in the area for instant temperature reading.

Multicamera tracking and 3D high resolution stereo imaging method can have their application in different areas; entertainment industry for camera and light tracking systems, surveillance systems, smart city systems, automated fire detection systems, fruit picking, multicamera ADAS (Advanced driver-assistance systems) systems any many more.

The company is searching for industry partners that can implement the technology in products and/or enhance the practical use of the technology. Partnership may include joint venture, technical cooperation or commercial agreement with technical assistance.

Advantages and Innovations

This is a new method of object tracking based on multi camera system for large area panoramic supervision. Different cameras are used to position PTZ (Pan Tilt Zoom) cameras for tracking, zoom in, and face detection or some other AI detection algorithm. 
Panoramic view will also ashore that PTZ(Pan Tilt Zoom) camera won't “lock and track” a single person while others pass surveillance area undetected.
Thermal cameras on the platform also can be used for human detection.

This system can detect the position of tracked object or a person. Having geo location tag over person, significantly reduces amount of computational power required in AI (Artificial Intelligence) tracking algorithms.

The system has multiple applications in surveillance domain (police, civil security, traffic, fire services), but also in others:

- Factory automation systems - where humans work alongside the machines. Multicamera system can be easily configured to drive the machines inside a warehouse. Within this system configuration, machines do not have to have any sensors for autonomous driving, they will be driven by a multicamera system.

- 3D high resolution stereo imaging
Multicamera tracking and 3D high resolution stereo imagining method can be implemented in entertainment industry for camera and light tracking systems, surveillance systems, smart city systems, automated fire detection systems, fruit picking, multicamera ADAS (Advanced driver-assistance systems) systems and many more.

System is using video cameras that are low cost, simple and easy to set up.

Stage Of Development

Under development/lab tested

Requested partner

The company is searching for partners that can implement the technology in products and/or enhance the practical use of the technology. The target partners would be operating in sectors such as: video surveillance, 3D mapping, automatic fire detection systems, automotive, warehouse automatization or entertainment technology. The potential partners could develop the products through a technical cooperation agreement or commercial agreement with technical assistance and it is possible to provide exclusivity in some application area. They are also open to investors for further develop of technology and its applications.
