The Development of Around View Monitoring System Pilot Type for Construction Equipment

Abstract

Recently, the interest on applying AVM(Around View Monitoring) systems in construction equipments have been increasing due to the demand for better control, work efficiency and safety. Most of the existing AVM systems have been developed focusing on the application in automobiles and only several AVM systems have been developed for construction equipments. However, the original technology of AVM remained the same as in the automobiles that failed to consider the main properties of construction equipments and suggest appropriate range of AVM display (Top-view). Therefore, the purpose of this study is to suggest a pilot type of AVM system for construction equipment. Accordingly, literature review, deduction of main consideration factors, selection of sensors, system design, algorithm development of a pilot type of AVM system for construction equipment have been conducted. A laboratory experiment has also been conducted for the deduction of further improvements. As a result, a minimum image refresh rate of 20 fps has been achieved that clearly reflects the actual situation of the equipment and also, the actual motions of Boom, Arm, Bucket have been displayed appropriately on the AVM system based on the angle data collected by sensors. However, the experiment results have also shown that the following tasks still remain for future work: 1)Improvement of AVM image interpolation, 2)Development of calibration module for variety construction equipment.

Development of all-in-one attachment-based PHC pile head cutting robot

“…For the productivity analysis of the automated PHC pile head cutting process (Yeom et al 2017b), the working scope (operating radius) of the automated robot was set as 7 m (Yeom et al 2016) considering the specifications and stability of the excavator used, and given the characteristics of the target job site, the working scope was divided into 15 zones (Figure 16). The average number of piles that can be worked on per zone was identified as 11.73, and analysis of the transport route of the dump truck based on the zoning results indicated that the longest traveling route was 131 m long.…”
