Embodiment Construction

[0059] like Figure 1-16 As shown, a method for measuring pantograph conductance and pull-out value based on monocular images, the method includes the following steps:

[0060] Step 1: Install the roof hardware equipment, which includes industrial cameras, strobe fill lights and control panels; the images of the industrial cameras are transmitted to the vehicle-mounted industrial computer for pull-out value and guide height calculation;

[0061] Step 2: Install the bottom vibration compensation module, the roof vibration compensation module is two laser triangulation ranging modules; the laser triangulation ranging module measures the height of the train chassis from the rail in real time, and transmits the height to the on-board industrial computer;

[0062] Step 3: Calibrate the industrial camera; the specific calibration steps are:

[0063] S1: Select a suitable calibration board to calibrate the industrial camera image;

[0064] S2: Place the calibration chessboard in fr...

Abstract

The invention discloses a pantograph conductor height and stagger value measuring method based on a monocular image. The method comprises the following steps: firstly, installing car roof hardware equipment, wherein the car roof hardware equipment comprises an industrial camera, a stroboscopic light supplementing lamp and a control panel, and the image of the industrial camera is transmitted to avehicle-mounted industrial personal computer for stagger value and conductor height calculation; and secondly, installing a vehicle bottom vibration compensating module, wherein the vehicle bottom vibration compensating module comprises two laser triangulation ranging modules, the laser triangulation ranging modules are used for measuring the height from a train chassis to a rail in real time andtransmitting the height to the vehicle-mounted industrial personal computer. The invention provides a railway pantograph and overhead contact wire system real-time detection method based on a single camera, which is a non-contact type method and cannot cause bad influence on normal operation of a train, the cost of the method is far lower than that of other methods, and simultaneously, errors caused by train vibration are also taken into account, so that the accuracy of detection is further promoted. According to the method, real-time monitoring can be carried out on the state of a railway pantograph and overhead contact wire system, and real-time early warning can be performed on possible accidents.

Description

technical field [0001] The invention belongs to the field of pantograph conductance and pull-out value measurement, and relates to a monocular image, in particular to a method for measuring pantograph conduction height and pull-out value based on the monocular image. Background technique [0002] There are the following methods in the prior art for measuring the pantograph conductance height and pull-out value of monocular images, but all of them have corresponding deficiencies and defects; [0003] 1. Contact measurement; this method installs a proximity sensor on the pantograph slide to form a detection array, and dynamically measures the geometric parameters of the catenary based on the contact method. This method needs to install a large number of proximity sensors on the pantograph head. When the train is running, the windward area of ​​the pantograph is increased, and the following characteristics of the pantograph are reduced, which has the disadvantages of low reliab...
