Measurement of truck carriage volume with laser triangulation

The principle and solution for measuring truck carriage volume with laser triangulation was introduced. The key technologies of the measurement system were also described. Focus was on the process of how to build the measuring system and its components in this paper. In the measurement system, the key technology of the segmenting truck carriage was presented in detail. With the third gray moment for edge detection algorithm, the volume of the carriage with all kinds of axles could be calculated without considering its head and underframe. In addition, the number of laser system could be downsized to 2 by rolling-over and merging of the cross section data of truck body. The above techniques were already utilized in the project of carriage volume measurement. Large volume of data prove its feasibility.
