The rudder angle acquisition system can provide good data basis for steamship experimental analysis to ensure a driver can grasp the sailing direction accurately, so that the operation during sailing can be performed well.
Description
Technical field
The present invention relates to digital camera rudder angle acquisition analysis system and carried out the method for data handing with this system.
Background technology
Boats and ships can be in water according to driver's intention navigation, boats and ships are changed course or keep and specify the course, rely on to change rudder angle and realize.Helm indicator is the indispensable equipment of all size boats and ships that ride the sea, and its effect is that the rudder angle azimuth information in the ship's navigation is sent to positions such as driving steering.
Rudder angle metering system in the past is: a people reads the rudder angle number, and a people observes stopwatch, people's counting, the hand-kept rudder angle changes numerical value, for test post analysis usefulness, this process needs three people to carry out simultaneously at least, and precision, frequency all can not well be guaranteed.
The hand-kept rudder angle changes the mode of numerical value except the drawback that waste of manpower, precision can not get guaranteeing, the state-of-art of this mode and high speed development extremely are not inconsistent.
In shipping development more and more intelligentized today, be completely free of the human element in the test, adopt the digitalisation means to solve the problem that real rudder for ship angle is measured in real time, the developing direction that has necessitated.For avoid influencing accuracy of instrument, to boat on precision instrument discomforts such as rudder angle and helm indicator be fit to do under the situation of a large amount of changes, the non interference of collection also receives much attention.
Summary of the invention
At this present situation, the application's goal of the invention be to provide a kind of based on digital image processing techniques full automaticity rudder angle acquisition analysis system and carry out the method for data handing with this system, handle by image acquisition and digitized image, at limited condition on the particular surroundings of full scale test and the boat, break away from the observational error that human element causes, do not disturbing under the situation of facilities such as accurate instrument, adopt acquisition technology, digital image processing techniques, utilize the full automaticity collection of pick up camera and portable computer realization, for the follow-up test analysis provides accurate data to rudder angle.
In order to finish the application's goal of the invention, the present invention by the following technical solutions:
A kind of digital camera rudder angle acquisition analysis system of the present invention, it comprises: rudder, helm indicator, pick up camera and computer processing unit, wherein: described pick up camera be contained in helm indicator directly over, the alignment lens helm indicator of pick up camera, pick up camera also links to each other with computer processor;
A kind of digital camera rudder angle acquisition analysis system of the present invention, wherein: described pick up camera links to each other with computer processing unit by information wire;
A kind of digital camera rudder angle acquisition analysis system of the present invention, wherein: described pick up camera links to each other with computer processing unit by Bluetooth adapter;
A kind of digital camera rudder angle acquisition analysis system of the present invention, wherein: described pick up camera is a digital camera;
Of the present inventionly a kind ofly carry out the method for helm indicator data handing with digital camera rudder angle acquisition analysis system, wherein: it may further comprise the steps:
(1) gathers the dial plate image of helm indicator in real time with pick up camera;
(2) above-mentioned image is transferred to computer processing unit;
(3) in computer processing unit, described image is carried out image digitization processing, characteristics of image identification, image characteristics extraction and data analysis successively, to obtain the angle that accurate rudder angle changes;
A kind of method of the present invention, wherein: described pick up camera per second is gathered 5-25 frame picture.
System of the present invention and carry out the site environment of the method for helm indicator data handing based on full scale test with this system, and the instrument on the ship is precision instrument, if helm indicators etc. change, its precision will be interfered, the change of precision will be given in driver's operating process and be brought unnecessary trouble, the mistake that the navigation course takes place is easily controlled, and causes the risk in the navigation process to take place.Based on above limited resource, the mode that pick up camera is set up in utilization is gathered the state picture of helm indicator, helm indicator is not done any change, can guarantee its independent operation under the state that is not affected fully, and again the state picture that collects further be analyzed with system of the present invention.It can make the driver grasp the navigation direction more accurately for the boat analysis of experiments provides the good data foundation, controls in the navigation process so that better carry out.

The specific embodiment
As shown in Figure 1, digital camera rudder angle acquisition analysis system of the present invention comprises: rudder 1, helm indicator 2, pick up camera 3 and computer processing unit 4, pick up camera 3 be contained in helm indicator 2 directly over, the alignment lens helm indicator 2 of pick up camera 3, pick up camera 3 also link to each other by information wire or by Bluetooth adapter with computer processor 4.Pick up camera 3 is a digital camera.
As shown in Figure 2, of the present inventionly carry out the method for helm indicator 2 data handings with digital camera rudder angle acquisition analysis system, it may further comprise the steps:
(1). gather the dial plate image of helm indicator 2 in real time with pick up camera 3; Pick up camera 3 per seconds are gathered 5-25 frame picture; The fastest collection 25 frame pictures of pick up camera 3 per seconds;
(2). above-mentioned image is transferred to computer processing unit 4;
(3). in computer processing unit 4, described image is carried out image digitization processing, characteristics of image identification, image characteristics extraction and data analysis successively, to obtain the angle that accurate rudder angle changes.
By image acquisition the state picture that collects is transferred to and carries out image digitization in the computer processing unit 4 and handle, system utilizes digital image processing techniques then, the resource picture is carried out feature identification, image characteristics extraction and data analysis, realize the full automaticity collection and the analysis of rudder angle gauging process.
Because image acquisition obtains is data on the helm indicator, these data have directly been reacted the rudder angle location information in the ship's navigation, so rudder angle information that is that image digitization is handled, whole process has reduced the complexity of system, guaranteed the precisely interference-free of instruments such as helm indicator, reduce systematic error, improved the precision of rudder angle gauging simultaneously.
This invention selects for use noiseless digitalisation shooting mode to realize the collection and the measurement of rudder angle information.
