Abstract
Diplomska naloga obravnava problem anomalij delovanja pri zajemanju slik z industrijsko kamero pri proženju z zunanjim signalom. Pri visokih frekvencah zajemov slik lahko prihaja do napak pri zajemu in v nalogi poskušamo locirati napake meritev in raziskati vzrok pojava posamezne vrste napake. Za ugotavljanje posledic napak pri procesu shranjevanja slik je bil vzpostavljen mikrokrmilniški sistem za hkratno krmiljenje LED-diod in proženje industrijske kamere. Eksperimentalni sistem v tem delu se je izkazal za dobro metodo za preverjanje zanesljivosti merilnega sistema z industrijsko kamero. Binarno vodilo, sestavljeno iz LED-diod z znanim zaporedjem kombinacij vklapljanja, ki jih snema kamera, prožena prek signala z mikrokrmilnika, je omogočalo enostaven način za dokazovanje izgubljenih slik brez potrebe po dodatnih merilnih napravah, saj smo poleg metapodatkov slik imeli na voljo tudi vizualni način potrditve, da je do napake pri zajemu prišlo.

Title:Testing the reliability of fast image capture with a camera in external signal trigger mode
Abstract:
The thesis addresses the problem of operational anomalies during image acquisition with an industrial camera triggered by an external signal. At high image acquisition frequencies, errors during image acquisition are possible; in this thesis, we attempt to locate measurement errors and investigate the cause of the occurrence of each individual type of error. For the purpose of determining the consequences of errors in the image storage process, a microcontroller system was established for the simultaneous control of LEDs and triggering of the industrial camera. The experimental system in this work proved to be a good method for verifying the reliability of the measurement system with an industrial camera. A binary bus consisting of LEDs with a known sequence of switching combinations, which were recorded by the camera triggered by a signal from the microcontroller, enabled a simple method for proving lost images without the need for additional measuring devices, since, in addition to the image metadata, a visual method of confirming that an image acquisition error had occurred was also available.

Keywords:industrial camera, high-speed image acquisition, external signal triggering, reliability testing, image transmission errors
