Abstract
The invented aiming method is characterized by that a beam splitter prism is placed in the front of laser distance sensor for measuring contact network line guide height to make the exit light-beam of the laser distance sensor be perpendicular to the incident face of beam splitter prism. A camera head is placed under the incident face of the beam splitter prism to make the optical axis of said camera head be perpendicular to incident face of the beam splitter prison, and perpendicular to exit light-beam of laser distance sensor, the video output of the camera head is connected with display. When the image of measured object is coincided with crosspoint of cross-line of camera head, the aiming can be define.
Description
Technical field
The present invention relates to the contact net measuring aiming method that the electrification railway contact net geometric parameter detects.
Background technology
Present known electrification railway contact net method of sight is to adopt optical mode, form by one group of lens and cross differentiation plate, scioptics are imaged on measured target on the cross differentiation plate, and the cross wire on the image of target to be measured and the cross differentiation plate overlaps then represents run-home.
The image that adopts the optical sighting mode on view screen, to see, angle of field is all fixed, and the image size of seeing can't be adjusted and be inverted image, causes the workman can not quick identification netting twine to be measured.Influenced greatly by ambient lighting, daylight more by force, more weak all can cause image blurring.Aiming optical axis and range observation optical axis disalignment.Caused very big difficulty for accurate slewing like this.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of pointing accuracy height, fireballing electrification railway contact net measuring aiming method based on camera are provided.
The technical solution used in the present invention is:
This method of sight is to lead the place ahead of high laser distance sensor an Amici prism is set being used for measuring the contact netting twine, make the plane of incidence of the outgoing beam of laser distance sensor and Amici prism vertical, one camera is set under the plane of incidence below the Amici prism, make the optical axis of this camera vertical and vertical with the laser distance sensor outgoing beam with the Amici prism below plane of incidence, the video output of camera is connected with telltale, then is decided to be aiming when the image of measured target overlaps with camera cross wire point of crossing.
The image of contact netting twine directly sees through Amici prism and arrives camera, and the outgoing beam of laser distance sensor turns to 90 degree to arrive the contact netting twine by Amici prism.Make the light path of camera and the light path coaxial of laser distance sensor like this.Thereby eliminated the parallax that camera and laser distance sensor are produced when aiming, improved pointing accuracy.Utilize the cross line generation function of existing camera, when being overlapped with cross line, then be decided to be aiming by the image of survey line or point.Cross line can carry out the position adjustment by camera self software, provides convenience for calibration instrument like this.The minimal illumination of camera is 0Lux, so just can adapt to the various light intensity occasions that human eye can be experienced.Open the infrared mode of camera, add the narrow band pass filter of 635 nanometers, can get rid of the influence of natural daylight fully in the camera lens front.
The present invention adopts camera aiming, aims at optical axis and range observation light shaft coaxle simultaneously, and pointing accuracy height, speed are fast, adapt to all kinds of natural light environments.

The specific embodiment
Embodiment:
Fig. 1 has provided structure principle chart of the present invention.This method of sight is to lead the left of high laser distance sensor 3 and place an Amici prism 1 being used for measuring the contact netting twine, and makes the right side plane of incidence of the outgoing beam of laser distance sensor 3 and Amici prism 1 vertical.Under the plane of incidence below the Amici prism 1, place a camera 2, and make the optical axis of this camera 2 vertical and vertical with the outgoing beam of laser distance sensor 3 with the Amici prism below plane of incidence.The video output of camera 2 is connected with TFT telltale 5.
The image of electrification railway contact net line directly sees through Amici prism 1 and arrives camera 2, and the outgoing beam of laser distance sensor 3 turns to by 90 degree and arrives the contact system line.Make the light path of camera 2 and the light path coaxial of laser distance sensor 3.Fig. 2 has provided image capture displaying principle figure of the present invention, camera 2 is connected with the TFT telltale 5 of low-power consumption, the vision signal of camera 2 is passed to TFT telltale 5, the cross line that camera 2 itself produces is presented on the telltale, and the image of tested contact netting twine overlaps with the cross line point of crossing then to be represented to have aimed to contact netting twine.Start the laser measurement sensor and send laser, diffuser reflection takes place in laser on measured target, and the diffuser reflection light beam is received by the receiver lens of laser distance sensor, obtains contacting netting twine by built-in circuit analysis processing and leads height.
The present invention utilizes the cross line generation function of existing camera, and for aiming provides great convenience, cross line can carry out the position adjustment by camera self software, provides convenience for calibration instrument like this.The minimal illumination 0Lux of camera can adapt to the various light intensity occasions that human eye can be experienced.Open the infrared mode of camera, can get rid of the influence of natural daylight fully.
The present invention has improved the practicality and the applicable area of instrument, increases the degree of automation of instrument.The pointing accuracy height adapts to all kinds of natural light environments, has improved measuring speed, alleviates labor strength.
