Title: Success rate monitoring of the selected volleyball spiker game moves in the male extraleague. Aim: The aim of the thesis is to find out the success of the players in the hitter's position in the best eight teams of the men's volleyball extraleague on the pass and on the attack. Method: The thesis is based on empirical research using the technique of data collection using indirect observation, survey and video analysis of selected matches. Results: The results confirmed that the second spikers were better players in the passing ball than first spikers. It was further confirmed that the first spikers were better attacking players than second spikers. The first spikers were more used in the attack than second spikers, it wasn't confirmed. Keywords: Volleyball Spiker Pass Attack Male extraleague Statistics

Sammanfattning Undersökningens syfte är att förstå hur noggrann UAS-fotogrammetrin i dagsläget (2013) är.  Frågeställningarna som undersökningen utgick ifrån var: kan UAS-fotogrammetri i dagsläget ge precisa punkter med hjälp av att mäta in centrum av 1x1 meter utlagda plattor som kan ses i ortofoto?;  Kan det ge snarlik noggrannhet med pixelstorleken? samt Kan UAS-tekniken idag användas för att producera pålitliga höjdmodeller? För att uppnå syftet har en undersökning utförts med jämförelse på koordinater insamlade med totalstation och insamlade med UAS-fotogrammetriska metoder. Resultatet visade att medelfelet var drygt 1 pixel på plana koordinater samt på koordinater i höjd. Pixlarnas storlek var mellan 4.7-9.3 cm. Största felkällan ser ut att vara upplösningen på bilderna, men tekniken utvecklas fort. UAS-fotogrammetrin lever väl upp till frågeställningarnas förväntningar. / Abstract The purpose of the study is to understand what the accuracy of UAS photogrammetry today (2013) is. The study was based on the following questions: Can UAS photogrammetry today give precise points, measuring the centre of 1x1 meter plywood boards viewed from an orthophoto?; Can it give similar accuracy as the size of the pixels? And can UAS technology today be used to produce elevation models of good quality? To investigate these questions, a study has been made to compare coordinates collected from a total station and UAS photogrammetric methods. The results show that the standard error is approximately 1 pixel on flat coordinates and 1 pixel on elevated coordinates. The pixel size was between 4.7 and 9.3 cm. The biggest source of error seems to be the resolution on the pictures, but the technology develops quickly. The UAS photogrammetry method definitely meets the expectations of the questions.
