Review of automatic lifting obstacle detection technology for prefabricated building prefabricated components

Abstract

According to the different types of sensors used, the automatic lifting obstacle detection technology of prefabricated building prefabricated components was reviewed, and various obstacle detection techniques were analyzed. These technologies mainly include prefabricated obstacle detection technology based on laser radar, prefabricated obstacle detection technology based on millimeter wave radar, precautionary obstacle detection technology based on computer vision, and obstacle detection technology based on optical flow prefabricated components. At the same time, the author points out that any effective obstacle detection system can’t rely on a single sensor for environmental perception. Therefore, it is a research focus and difficulty in the field to detect the automatic lifting obstacles of prefabricated building prefabricated components by using various sensor information fusion technologies. In addition, in the context of the 13th Five-Year National Key R&D Program, the efforts in the “2018 Green Building and Construction Industrialization” project were introduced.
