Embodiment 1

[0017] Embodiment 1, a kind of automatic recognition method based on plane embossed characters on the train bogie, the recognition method is realized by a character recognition instrument, and the character recognition instrument is composed of a CMOS industrial camera [1], a housing [2], and 2 LEDs Light [4], 2 rod structures, support rod [10], LED display screen [12], industrial computer [13] equipped with character image processing software, image acquisition card [15]; wherein, 2 LED The lamps are respectively installed on two identical rod structures, and the two rod structures are distributed symmetrically about the center of the housing; the rod structure and the housing are connected by screws [9], one end of the support rod is fixed on the housing, and the other end It is used to connect with the rod body [7] to support the rod structure; there are two symmetrical handles [11] on the housing, a CMOS industrial camera is installed inside the housing, and the end of the ...

Embodiment 2

[0018] Embodiment 2. An automatic recognition method based on plane embossed characters on the train bogie, wherein: the bar structure includes a rotating support [5], a piston rod [6], a bar body [7], and a rotary button [8] ], there is a hydraulic structure in the body of the rod, by controlling the rotation of the rotary button, the change of the hydraulic structure in the body of the rod can be controlled, and then the extension and retraction of the piston rod can be controlled; the rotating support is used to install the LED lamp, which can Realize the rotation of the LED light in the plane where the center of the piston rod is located, the rotation angle is between 0° and 180°, so that the angle between the LED light and the character background plane is a variable inclination angle, and the inclination angle is between 20° and 45° space; the purpose of the two rods is to enable the two LED lights to produce low-angle lighting at the flat embossed characters on the train...

Embodiment 3

[0019] Embodiment 3, an automatic recognition method based on plane embossed characters on the train bogie, wherein: 2 LED lamps all contain rechargeable batteries inside, when the power of the batteries is exhausted, the brightness of the LED lamps will dim, so The LED lamp can be disassembled from the swivel support of the L-shaped piston rod and charged.

Abstract

The invention discloses an automatic recognition method based on plane embossed characters on a train bogie. The technical solution adopted by the present invention to solve the technical problem is: two identical LED lamps are respectively installed on the rotating supports of two identical piston rods. At the same time, the reflected light generated in the character background area cannot effectively enter the CMOS industrial camera, and only part of the diffuse reflected light enters the CMOS industrial camera. Camera, so that the contrast between the character outline and the character background outline is improved in the CMOS industrial camera to form a character image; the CMOS industrial camera collects the character image signal and transmits it to the industrial computer for processing. After the industrial computer is processed, the character image signal The transmission is displayed on the LED display.

Description

technical field [0001] The invention relates to an automatic recognition method based on plane embossed characters on a train bogie. Background technique [0002] The characters on the train bogie are embossed characters. For a long time, the staff used manual recognition when recognizing such characters, that is, while observing with human eyes, they registered with a pen. This artificial recognition method is not only inefficient, but also easily recognizes wrong characters. [0003] The embossed character on the train bogie is a kind of concave-convex character, which has the following characteristics: the character is convex or concave, and is a three-dimensional character; the material of the embossed character is the same as the background material, and there is no color difference; the embossed character passes Poor reflection imaging; characters are generally smaller in size. Obviously, the existing character recognition methods cannot effectively recognize the emb...
