In this section, the high-sensitivity high-reliability climate-protected optoelectronic systems are presented. All of the optoelectronic systems contain 2 surveillance channels – visible and thermal-imaging – and are batched with high quality lenses with fast aperture and minimal optical distortions.
The distinguishing feature of all presented optoelectronic systems is the availability of built-in data mining and intelligent image processing functions for both surveillance channels. The built-in analytics allows to drastically decrease requirements to the server and therefore its cost. With the traditional approach sever performs the decompression of the archived video stream MPEG, H.264, performs an analysis of image for any security threats according to its algorithms, repeats archivation and writes data to the archive. Heavy load on the serves often leads to a server crash and therefore security block outage, which is unacceptable for most object categories.
Algorithms applied in ASTROHN optoelectronic security and surveillance systems allow to construct a 3D scene model in reliance on horizon and perspective, classify and select monitored events by these factors:
