Bar cross section type in spatial mesh structure is mainly steel pipe, the specification of section generally use national regulation.
In the prior art, category is detected to the sectional dimension of the components such as rod piece, solder sphere in spatial mesh structure
In a kind of conventional detection.Especially to no drawings spatial mesh structure need to the sectional dimensions of most of rod pieces, solder sphere into
Row is taken a sample test or detected totally when, traditional method is measured with the vernier caliper of large size.But due to space lattice knot
The rack of structure is usually relatively high, therefore is typically necessary and sets up scaffold or live high-altitude operation vehicle and can just measure, and has
A little projects are because place limitation can not set up scaffold or use high-altitude operation vehicle, it is sometimes necessary to which working at height personnel walk in steel pipe
On measure.Moreover, even in this way, the top boom in spatial mesh structure also is difficult to measure.
In addition, though riding track has also been set up in some spatial mesh structures in the prior art, but on the riding track
The rod piece that riding track periphery can only be measured still is unable to measure from the rod piece of riding track remotely.So either using, all compare
It is relatively time consuming laborious, and testing staff also has comparable operating risk (for example, risk etc. of working at height).
In recent years, with the continuous development of 3-D scanning technology, 3-D scanning technology can also be used to survey in the prior art
The size of all rod pieces in quantity space network.But equipment used in above-mentioned 3-D scanning technology is somewhat expensive, data
Post-processing it is also more complicated, no Site Detection is fast intuitive；Although moreover, far measuring distance, measurement error also compares
Greatly.
