| titleOfInvention | Contact net geometric parameter dynamic testing method based on triangulation |
| abstract | A kind of contact net geometric parameter dynamic testing method based on triangulation, applies on vehicle-mounted bow net dynamic monitoring system or hand propelled contact net inspection car, includes the following steps：(1), obtain the pixel coordinate (xPixel of contact net in image,) and the angle change (xAngle of detection device yPixel, yAngle), (2), entire test scope is divided into N sections by data processing, every section is demarcated, so as to make one group of camera calibration parameter of every section of formation；By the pixel coordinate acquired in step (1), judge and obtain the calibrated altitude section that the pixel coordinate is located at, then the camera calibration parameter by the height section, obtain stagger, lead high level；(3), Data correction by calibration shift, obtains the stagger of contact net reality and leads high level；(4), the gradient calculates；The present invention using principle of triangulation, can effectively detect leading for contact net is high, pull out, line-to-line away from and the gradient, ensure the measurement accuracy in entire range, eliminate large range of error. |
