Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this hair
Bright embodiment, those of ordinary skill in the art's every other implementation obtained without creative labor
Example, belongs to protection scope of the present invention.
Referring to attached drawing 1, the embodiment of the invention provides a kind of viewpoints virtually shown applied to offshore oilfield safety protection three-dimensional
Control method includes the following steps:
Step 1 reads the location information of each facility and outer dimension information and target in offshore oilfield facility attribute list
Ship current motion information；
Step 2, the spacing for calculating separately target ship Yu each offshore oilfield facility choose the nearest facility conduct of spacing
" potential shelter " is analyzed；
Step 3, according to " potential shelter ", the position coordinates of target ship and current view point, judge that position is closed between three
It is and takes different operation,
If the spacing of target ship and " potential shelter " is less than or equal to one times of " potential shelter " length, view is reduced
Point height of observation is allowed to horizontal with the holding of target ship, executes step 4；
If the spacing of target ship and " potential shelter " is greater than one times of " potential shelter " length, and is greater than object ship
When only with viewpoint spacing, original viewpoint position is kept, executes step 5；
If the spacing of target ship and " potential shelter " is greater than one times of " potential shelter " length, and is less than or equal to
When target ship and viewpoint spacing, evasive action adjustment viewpoint position and observation posture are carried out to viewpoint, execute step 4；
Step 4 judges whether viewpoint is avoided " potential shelter ", if having avoided executing step 5, if not avoiding executing step
3；
Step 5, according to step 3 and step 4 processing result combining target vessel motions data, with target ship motion information
Real-time update viewpoint position.
In the embodiment of the present invention, each facility in the offshore oilfield security protection region is stored in offshore oilfield facility attribute list
Title, retrieval serial number, geometric center position coordinates, length, width and height.As shown in appendix 1.
Table 1
In the embodiment of the present invention, in step 4, the method that judges whether viewpoint is avoided " potential shelter " specifically: calculate mesh
Mark the azimuth angle interval of target ship where angle between ship geometric center and " potential shelter " length both ends；Calculate viewpoint with
Target ship azimuth, judge viewpoint azimuth whether the azimuth angle interval locating for " potential shelter ", if then not
It avoids, if otherwise avoiding.
Schematic diagram is obscured by an object referring to fig. 2 for observation object.It is (x that A, which is observation point coordinate, in figurea, ya, za)、(ha, pa,
ra), observation visual angle is α, and B point is the shelter in object observing, and coordinate is (xb, yb, zb), it is highly h, width w, C point is
Observed target, coordinate are (xc, yc, zc)。
Calculate point of observation and observed target range:
By formula 1 it is found that can determine whether it to observed object not structure if " potential shelter " and point of observation distance are greater than L
At influence, otherwise continue lower step judgement.
Point of observation direction of observation is ha, point of observation and shelter orientation:
The maximum height of observable target occlusion object:
By formula 2, formula 3 it is found that ifIt may determine that the object then to hide
Block material must take evasive action.
In the embodiment of the present invention, in step 3, evasive action is carried out to viewpoint specifically: according to the position of offshore oilfield facility
The location information of confidence breath and geological information and target ship, calculates viewing blind zone angular interval, establishes with target ship seat
It is designated as the center of circle, viewpoint and target ship spacing are the circus movement locus model of radius, utilize the blind area angular area having calculated that
Between with circus movement locus model, uniformly adjust viewpoint position be allowed to remove blind area angular interval, to reach evasive action
Purpose.
It is rotating avoiding schematic diagram referring to Fig. 3.A circle indicates that circle where shelter, B circle are circle where point of observation in figure.It hides
Block material shared angle in circle A is observation point move angle.
Shelter and observed target range:
β value can be calculated by formula 4 are as follows:
After New Observer point is moved to from former point of observation, formula 1,5 is utilized to calculate new coordinate are as follows:
xnew=L × sin β+xa (6)
ynew=L × cos β+ya (7)
hnew=ha+β (8)
Using formula 6-8 it can be concluded that new coordinate are as follows: (xnew, ynew, za)、(hnew, Pa, ra)。
Former point of observation can not observe target since shelter obstructs, and update point of observation coordinate to newly by calculating
Point of observation, so as to complete observation target.
In the embodiment of the present invention, in step 5, real-time update viewpoint position method specifically: aobvious in each three-dimensional
Show in frame image, according to target ship changes in coordinates, calculates update eye coordinates in real time, to ensure viewpoint in each frame image
Relative target ship position remains unchanged.
Known synchronization eye coordinates (xview, yview, zview), target ship coordinateThen with mesh
Mark ship is coordinate origin, and viewpoint and target ship relative coordinate are (δx, δy, δz):
According to renewable time ship coordinateAnd viewpoint and target ship relative coordinate
(δx, δy, δz), then there are renewable time eye coordinates are as follows:
The embodiment of the invention provides a kind of viewpoints' integration methods virtually shown applied to offshore oilfield safety protection three-dimensional, lead to
Cross read the current location of the offshore oilfield facility attribute list and target ship with location information and outer dimension information with
Exercise data calculates offshore oilfield facility and target ship distance, chooses away from the nearest offshore oilfield facility of target ship, analysis should
Relative positional relationship in conjunction with the location information of current view point judges the offshore oilfield facility between the two for facility and target ship
Whether present position blocks the observation to target ship, using judging result, target ship and field facility relative position and
The coursespeed information of target ship, dynamic calculates the azimuth information of viewpoint in real time, to reach optimal viewing effect.Using this hair
The viewpoints' integration method for being applied to offshore oilfield safety protection three-dimensional and virtually showing that bright embodiment provides, no manual operation the case where
Under, offshore oilfield setting, target ship and viewpoint three's positional relationship are judged automatically, and according to judging result to viewing point
