THE EFFECT OF TWO- THREE-DIMENSIONAL DISPLAYS ON REMOTE CRANE CONTROL PERFORMANCE

摘要

A local freight company has implemented a camera-based system to pick-up and land containers from a yard onto a prime mover and vice versa. However, a two-dimensional (2-D) camera-based system deprives the operator of the depth perception required for container handling. In particular, the operator may encounter difficulties in judging the speed of container landing, and the distance of the container to the prime mover chassis and to another container. To support depth perception, a three-dimensional (3-D) camera and display system may be developed to enable stereoscopic vision. A mock-up of such a system that includes basic crane controls is being built, to enable an assessment of the efficacy of the proposed 3-D set-up. The assessment will involve performance testing with subjects. The results of the tests will be reported at a later date. This paper reviews the shortcomings of the existing 2-D system and describes the set-up constructed to enable performance tests on the 3-D system proposed.
