Said synchronous trigger circuit plate (65) converts said TTL square wave into LVDS or the RS232 signal said trigger pip as said camera (3), and said LVDS or RS232 signal are sent to said camera (3).
13. tour detection method according to claim 7 is characterized in that, in said second step, the said image processing system of said host computer (7) carries out analyzing and processing to said target image and comprises the steps:
The first step, the image pre-service: said image processing system smoothly reaches denoising to target image and handles, thereby obtains muting target image;
Second step; Zone identification: said image processing system is discerned the various zones of said muting target image; Said muting target image is divided into rail zone, sleeper zone and non-rail zone, and with the input picture of each zone as follow-up defects detection;
In the 3rd step, defects detection: said image processing system detects, analyzes said input picture, thereby judges, obtains the concrete zone at defective place and the kind of said defective;
The 4th step; Defect location: the real-time speed that obtains said tour detection system operation according to the tachogenerator (61) of said external trigger module (6); Obtain the range ability of said tour detection system; The information of said range ability is one to one with the sequence number of the said target image of being gathered, and according to the corresponding relation of said range ability and detected said defective, writes down said defective and in motion process, appears at the accurate position on the said object (9);
The 5th step, Symptom and classification: from said rail zone, said sleeper zone and the corresponding different geometric characteristic of the detected said defective in said non-rail zone, utilize said different geometric characteristic said defective is described and to be classified;
In the 6th step, report output: the said defective that will describe and classify is exported as said analysis result.
