Abstract

Prometna signalizacija predstavlja važan infrastrukturni element u cestovnom prometu, a glavna joj je zadaća prenositi informacije sudionicima u prometu. Danas, osim ljudskim sudionicima u prometu, prometna signalizacija, naročito oznake na kolniku i prometni znakovi, informacije prenose i naprednim sustavima pomoći vozaču (engl. Advanced Driver Assistance Systems – ADAS). Svrha navedenih sustava je da prikupljajući informacije iz okoline pomažu vozaču tijekom vožnje, te na taj način doprinose... More povećanju sigurnosti cestovnog prometa. Za prikupljanje informacija i percepciju okoline, ADAS sustavi koriste različite senzore poput kamera, radara te lidara. Na kvalitetu detekcije navedenih senzora utječe niz faktora, a jedni od njih su i vremenski uvjeti. Naime, kiša, magla, snijeg, sunce i ostali vremenski uvjeti mogu utjecati na kvalitetu i točnost prikupljanja informacija iz okoline, a time i na detekciju oznaka na kolniku i prometnih znakova što u konačnici može negativno utjecati na pravilan rad određenih ADAS sustava. Slijedno tome, cilj ovog diplomskog rada je prikazati kako i u kojoj mjeri različiti vremenski uvjeti utječu na detekciju prometne signalizacije ADAS sustavima u vozilima. Senzori kao što su kamere pokazuju loše rezultate pri jakom bliještanju, zalasku sunca ili sumraku te bolje prepoznaju oznake na kolniku povećanjem kontrasta i retrorefleksije. U uvjetima kiše ili magle se lidarima i radarima sposobnost detekcije smanjuje zbog slabljenja intenziteta primljenog signala. Less

Abstract (english)

Traffic control devices are important road infrastructural elements, and their main task is to transfer information to road users. Today, except to humans, traffic control devices, especially road markings and road signs, convey information to Advanced Driver Assistance Systems (ADAS). The purpose of those systems is to collect information from the environment and based on that information assist the driver, thus contributing to increase of road safety. To collect information and perceive the... More environment, ADAS systems use various sensors such as cameras, radars and lidars. The detection quality of the mentioned sensors is affected by a number of factors, one of which are weather conditions. Namely, rain, fog, snow, sun and other weather conditions can affect the quality and accuracy of gathering information from the environment, and with that the detection of road markings and traffic signs, which can ultimately negatively affect the proper operation of certain ADAS systems. In addition, the goal of this master thesis is to show how and in what extent different weather conditions affect detection of traffic signaling. Sensors such as cameras have significantly lower detection rate when there is high sun glow, sunset or dawn and perform better when there is higher contrast and retroreflection. With radars and lidars rate of detection is lower in conditions of rain and fog due to lower intensity of received signal. Less
