Description
Technical field
The present invention relates to automobile navigation technology and vehicle automation fields, and in particular to is suitable for the nothing of indoor and outdoor navigation
People drives trolley navigation system and unmanned trolley.
Background technology
The navigation mode of unmanned trolley (Automated Driving Vehicle, abbreviation ADV) is determined by its group
At logistics system flexibility and reliability when system operation, with the development of science and technology, the navigation mode of ADV is also a variety of
It is various, according to the form of ADV navigation circuits, fixed route navigation mode and free path navigation mode can be divided into.Fixed route
Its cost of navigation mode is relatively low, and positioning accuracy is higher, also more stable reliable, but path is limited, to site environment require compared with
It is high；Free path navigates, and mode its path changeover is flexible, and flexible, the requirement to site environment is relatively low, but its positioning accuracy by
The influence of device therefor and Navigation Control algorithm causes the case where obtaining positioning accuracy same with fixed route navigation mode
Under, the cost higher of ADV.
Currently, unmanned trolley commonly navigates, mode is laser navigation mode, optical guidance mode, tape navigation side
Formula, vision guided navigation mode and electromagnetic induction navigation mode.The advantage of electromagnetic induction navigation mode is that leading line is hidden, is not easy dirt
Dye and breakage, principle is simple and reliable, at low cost, however the complexity of its guidance path is limited, and expands or change battle line very
Trouble, lacks flexibility.Optical guidance mode be by walking path paint or paste colour band, by optical sensor adopt into
Colour band picture signal is easily recognized and is handled to realize navigation, and guidance path setting is more flexible, but is polluted to colour band
It is very sensitive with damaging, easily limited by site environment.It is relatively easy that the advantage of tape navigation mode is that its tape is laid with, and change is led
Bit path is also easier, but easily contaminated, is easily limited by external environment, is suitable for the preferable condition of environment.Laser navigation
Mode obtains advantage and is flexible, and without carrying out any processing to ground, path changeover is flexible and convenient, is suitable for various live rings
Border can conveniently change kinematic parameter and driving path, but its control and navigation algorithm are the most complicated, and positioning accuracy takes
Certainly in laser head and algorithm, cause the cost of ADV higher.Vision guided navigation mode obtains exemplary advantage and is ADV low costs, obtains
What is taken contains much information, and can build the three-dimensional map of panorama, it can be achieved that full-automatic navigate, however it is affected by live light,
Information processing capacity is big, and Current hardware equipment is difficult to meet its requirement of real-time, and image processing algorithm is not yet ripe.
In addition, 1 (publication number of patent document：101387522 A of CN) disclose a kind of electromagnetic tracking based on inductance coil
Method, though control and navigation algorithm are simple, it is of low cost, navigation accuracy by induction coil quantity and influence of arrangement, outside
See larger, inconvenience is used for small-sized ADV, and need to redesign number of coils and layout for different environment, excessively troublesome.
Further more, 2 (publication number of patent document：103048996 A of CN) disclose drawing automatically based on laser scanning and ranging instrument
Guide-car, system and air navigation aid, though it is then navigated using laser scanning environment construction map, relative to traditional based on anti-
Plate laser navigation mode is penetrated, the requirement to environment further decreases；But its positioning accuracy depends critically upon coding angle, gyro
Instrument, laser head and algorithm, and need more than two laser heads, cause navigation and control algolithm is complex and ADV
Cost is higher.
Patent document 3 (103777637 A of CN) discloses a kind of areflexia Laser Self navigation ADV trolleies and its navigation
Method is navigated using the method for single laser scanning environment construction map, and reflecting plate laser navigation side is based in contrast to tradition
Formula is with for more laser navigations, and requirement and algorithm to site environment further decrease, but its path planning depends critically upon
Motor encoder and gyroscope, and the calculation amount of the air navigation aid is excessive, and the complexity of navigation and control algolithm is excessively high, causes
The cost of ADV is also high.
