Optical Scanners - Suspension Kinematics Points Measurement
Souček, Ondřej ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The master´s thesis deals with creating a usable methodology for measuring the position of kinematic points McPherson suspension using optical scanners available on ÚADI. The answer lies in comparing the measurement results obtained using the scanners ATOS and TRITOP with regard to the different measurement methods. Using analytic geometry and the software ADAMS are fixed characteristics of the suspension, they are compared with values measured on the geometry. Finally, it evaluated the accuracy of measurement methods.

Measurements of the object position and velocity by using optical scanners
Uncajtik, Petr ; Říčný, Václav (referee) ; Kratochvíl, Tomáš (advisor)
The objective of Master’s Thesis is to research the utilization of line optical sensors for object location´s and speed measurement in cooperation with PROTOTYPA company. At the beginning of the Thesis there is an explanation of CCD sensor components and photodiods working principals. Further are discussed particular methods of object sensing. There are schematics of different sensor locations and flying object. The other step deals with introduction to the question of ray impact on sensor in the way of using different light sources and optical systems. In the other part of the Thesis are presented two sensors, which have been chosen by PROTOTYPA company workers. Final part of the Thesis deals with description of executed experimental measurement with LCCD 2048S-14 type of sensor. Experiments are aimed for statical and dynamical processes. In statical part was checked displaying of fixed objects on CCD sensor in internal spaces on the assumption that changing of object-lens focalization, object´s high and shape. For the evaluation was used of MATLAB program. Dynamical part of measurement is aimed for moving objects.

Wheel Alignment and Kinematic Characteristics Measurement with Use of Optical Scanners Tritop and Atos
Dvořák, Martin ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
The diploma thesis is focused to possibility utilizing of optical scanners TRITOP and ATOS for set up geometry of wheels. In background research are described the most important parameters of wheel suspension and devices for measuring these parameters. Practical part is concerned with progression of measurement, results and with determination coordinates of kinematic points. These points are made 3D model of forward and backward suspension wheels. This model helps to make kinematic characteristics and its progression due to attitude of wheel. In last part is described possibility to utilizing of optical scanner ATOS to common measurement of geometry wheels.
