| Abstract: | The concepts of “confining structure” and structure light are illuminated in this paper. A laser theodolite with three freedoms
of rotation, which is aimed at “confining structure”, is developed. Various scanning modes and their mathematical models based
on laser theodolite with three freedoms of rotation are discussed. According to the features of a huge object the structure
light engineering surveying based on laser theodolite with three freedoms of rotation is determined as the main method in
an actual application. The observation of four sound concrete posts and forced centering plates. Subsequently, it is transformed
into the huge object coordinate system. The scanning mode with plumb plane is selected as the main mode in the whole work.
And other assistant methods, such as close range photogrammetry and the method of using reflection sheet, are applied to the
work of “scanning dead angle”. At last, a surveying accuracy estimation of this method is done and a surveying accuracy test
is finished. It can be concluded that the structure light engineering surveying based on laser theodolite with three freedoms
of rotation is considered to be an effective and applied method, and has many superiority to some other surveying methods
in the work of surveying “confining structure”. |
