Abstract

A moving thing recognition system using a camera on a path that the moving thing (such as a train, vehicle or ship) is proceeding, in which a check aligning device is used to align each picture file of the moving thing with virtual checks to compare for the body type and speed of the moving thing. The virtual checks of the moving thing are provided in taking the length of a fixed marking article or some other fixed article on the path of the moving thing as a reference. Thereby, under the circumstance that the path of the moving thing is unchanged and there is no emitted signal, accurate recognition can be obtained.

a body-type comparing device to judge said body type of said moving thing using a way of comparing pictures from said picture file taken by said camera.

9. The moving thing recognition system as claimed in claim 8, wherein said body-type data base, said check aligning device, said body-type comparing device and said body-type comparing device are provided in a rear-end servo;

while said data of picture file taken by said camera are sent to said rear-end servo in a way of cable or wireless transmission for recognizing.

10. The moving thing recognition system as claimed in claim 8, wherein said camera takes pictures in a MJPEG form.

11. The moving thing recognition system as claimed in claim 8, wherein unit of said data of time is as small as micro seconds.

12. The moving thing recognition system as claimed in claim 8, wherein said moving thing is a train.

13. The moving thing recognition system as claimed in claim 8, wherein said moving thing is a vehicle.

14. The moving thing recognition system as claimed in claim 8, wherein said moving thing is a ship.

15. A moving thing recognition system comprising:

a camera set at an appropriate position on a path of said moving thing, and being set to have a picture taking range which at least is adapted to taking two picture files of said moving thing taken when said moving thing passes by said picture taking range;

a detecting device to activate said camera for taking a picture of said moving thing when said moving thing enters said picture taking range;

a GPS used to get data of longitudinal and latitudinal degrees and data of time of each of said picture files, thus file names of said picture files being established;

a check aligning device used to align each of said picture files of said moving thing with virtual checks;
