Abstract
The new approach for measuring the flatness of floors or other horizontal surfaces is based on the use of vehicle-mounted sensors that moves through these surfaces in a more or less automated way. It becomes competitive in relation to the classical methods using the straightedge and the wedge or tilts or geodetic methods used interchangeably. The measurement with vehicles requires, on the one hand, the movement of the sensors along the set lines, and on the other - the appropriate frequency and precision of the readings. Research and implementation works on the implementation of kinematic tacheometric measurements to the prism moved on the floor are still underway. These works cover two aspects: the measurement capability of the instruments and the precision of evaluation of flatness as a function of prism movement in certain directions on the tested area. These topics are the subject of scientific research and are periodically published. As the part of this work, kinematic measurements of the Leica TCRP 1201+ motorized tacheometer (RTS) have been performed to the prism mounted on a remote-controlled vehicle used in modeling and robotics. Measurement models (different scan variants) were developed, the reliability of the measurement axes' position by averaging between two wheels of the vehicle was analyzed, and tests that enabled determination of the accuracy of the totalizer-type measurement for the moving target were performed. Both scan variants were tested: (i) along fixed lines and (ii) along individually defined lines, obtaining comparable results (not exceeding 10%). As a result of the research, it was concluded that the adopted theses were confirmed and thus the applied approach could be used for measuring flatness of the floor.
