Description
Technical field
The present invention relates to the image acquisition technologies of container, specifically, being to be related to a kind of container surface image
And container number image-pickup method.
Background technique
A whole set of transportation system container maximum standardization for being successfully its product and thus established.It can allow
One tens tons of load-carrying of huge monster realizes standardization, and be done step-by-step in global range based on this ship, port
The logistics system that mouth, course line, highway, terminal, bridge, tunnel, multimodal transport match, this can be rated as since the dawn of human civilization really
One of great miracle of creation.
China is the first manufacture big country of container in the world at present, and creates three worlds the in this production field
One.China's container annual production capacity is up to 5,800,000 TEU(standard packing boxes), it ranks first in the world；Produce the specification kind world of container
First, China's container production is from dry cargo container to regular general cargo container and special container, box-type carrier vehicle, rule
Lattice kind up to more than 900, is able to satisfy various transportation demands；Container car sales volume the first in the world, world container volume of production and marketing are
3920000 TEU, wherein container car sales volume in China's is up to 3,740,000 TEU.
The use of cargo transport highly developed today at sea, container are customary, corresponding container
Examine work also very universal.The purpose of Container Survey essentially consists in the safe handling of determining container, avoids and prevent goods
The generation of damage.
But the acquisition of the container representation of the prior art has the disadvantage in that the case number (CN) of container representation and container is adopted
Collect low efficiency, detection of stopping is needed in cargo transport, is unable to continuous productive process, working efficiency is not high, in addition in collection process by
It will appear omission in the certain factors of operator, acquisition is not comprehensive, since container model difference needs replacing different acquisition sides
