The Method of Data Processing Using the Digital Camera Rudder Angle Acquisition and Analysis System

Abstract

The invention relates to a digital pickup rudder angle acquisition and analysis system. The system comprises a rudder, a rudder angle indicator, a camera and a computer processing unit; the camera is arranged above the rudder angle indicator; the camera lens of the camera is aligned with the rudder angle indicator; the camera is connected with the computer processing unit; a method for processing the data of the rudder angle indicator by using the digital pickup rudder angle acquisition and analysis system comprises the following steps of: (1) acquiring the dial image of the rudder angle indicator by using the camera in real time; (2) transmitting the image to the computer processing unit; and (3) performing image digital processing, image characteristic identification, image characteristic extraction and data analysis on the image in the computer processing unit to obtain the accurate changed angle of the rudder angle. 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 [0001] The invention relates to a data processing method using a digital camera rudder angle acquisition and analysis system. Background technique [0002] The ship can sail in the water according to the driver's intention, and the ship can change the course or maintain the specified course by changing the rudder angle. The rudder angle indicator is an essential equipment for ships of various sizes navigating at sea. Its function is to transmit the rudder angle and azimuth information during the ship's navigation to the steering and other positions. [0003] In the past, the rudder angle measurement method was as follows: one person reads the rudder angle number, one person observes the stopwatch, one person counts, and manually records the rudder angle change value for post-test analysis. This process requires at least three people at the same time, and the accuracy, frequency Neither can be well guaranteed. [0004] In addition to the disadvantages of was...

[0003] In the past, the rudder angle measurement method was as follows: one person reads the rudder angle number, one person observes the stopwatch, one person counts, and manually records the rudder angle change value for post-test analysis. This process requires at least three people at the same time, and the accuracy, frequency neither can be well guaranteed

[0004] In addition to the disadvantages of wasting manpower and the accuracy cannot be guaranteed, the method of manually recording the value of the rudder angle change is extremely inconsistent with the rapid development of science and technology.
