With the acceleration of globalization and regionalization of the world economy, port is playing an
increasingly important role for that it is an international transportation hub port interface and the support of
the international trade platform. How to effectively reduce labor costs, improve the working environment,
stable productivity, reduce the production cuts caused by human intervention and improve the management of
real-time monitoring of all the major ports has become a common issue faced. In order to achieve the
automatically stacking and reclaiming process of Stacker-Reclaimer in the bulk material yard, the source of its
control is expected to identify the stockpile in the bulk yard, including length, width, height, the starting
address, destination address, as well as Three-dimensional shape of the stockpile, since in the operation
process, stockpile changes the shape dynamically. As a result, the real-time three-dimensional shape and
coordinate of piles should be achieved. Based on the existing Stacker-Reclaimer in Qinhuangdao Port coal,
we study the large field of view real-time three-dimensional laser scanning imaging theory and technology.
The overall system design to achieving the three-dimensional laser scanning image is presented. The working
principle of the three-dimensional laser scanning imaging system is analysised. Moreover, the parameter
designation, the technical parameters and the composition of the whole system are all given. The research of
the thesis is also used for other large-scale three-dimensional modeling of piles and the volume computing. In
a world, the method has wide application prospect.
