A simple and quick composite two-dimension code recognition system comprises a recognition method and recognition equipment, and is characterized in that the recognition method comprises the following steps:
s1, performing two-dimension code composite design, namely, improving the traditional black-and-white two-dimension code into a color two-dimension code by adopting color composite design, but requiring that the selected color has obvious color difference;
s2, capturing two-dimension code characteristic information, and capturing the two-dimension code characteristic information at any time when the identification equipment is in an initial state;
s3, calculating a visual field area where the two-dimensional code is located, and quickly calculating the visual field area where the two-dimensional code is located after the characteristics of the two-dimensional code are identified in the state of an infrared filter of identification equipment;
s4, capturing two-dimension code information of different colors, quickly replacing a filter by identification equipment, and capturing the two-dimension code information of different colors under different filters;
s5, identifying the two-dimensional code information layer by layer according to a preset category and finally obtaining effective information;
s6, ending the process, and enabling the filter of the recognition equipment to be restored to the initial state;
the identification equipment includes camera support 100, pivot, filter clamp 300 and filter 400, camera support internally mounted has rotating electrical machines 101, rotating electrical machines 101's output shaft and pivot fixed connection, filter clamp 300 and pivot fixed connection, filter 400 inlays and establishes on filter clamp 300, just the pivot rotates and sets up on camera support 100, fixed mounting has collection camera 500 on camera support 100.
When the system is used, the color composite design can be adopted for the two-dimension code in advance, namely the traditional black-and-white two-dimension code is improved into the color two-dimension code, but the selected color is required to have obvious chromatic aberration, other colors can be filtered by the filter lens 400, wherein white is a reference color and is not influenced by the filtering of the filter lens 400;
and it should be noted that the two-dimensional code is composed of conventional black, white, and red, yellow and green colors. The selected color should have the following characteristic requirements: 1. obvious color difference exists among different colors; 2. and a corresponding filter is arranged, so that the color can be effectively screened.
The two-dimensional code reading device is provided with a plurality of color filter lenses 400, and the filter lenses 400 rotate along with the rotating shaft and can be placed in front of the camera lens according to the requirement for identifying the two-dimensional codes with corresponding colors;
after the filter lens 400 is penetrated, the corresponding color and white are bright and are regarded as white, and other colors are dark and are regarded as black, so that a black-and-white two-dimensional code image under the color is formed;
in summary, in the conventional two-dimensional code image, several pieces of two-dimensional code information can be generated according to the number of colors in the scheme, and when the amount of information to be carried is large, the information can be classified in advance according to the colors, that is, the two-dimensional code values in the colors, and the information can be identified layer by layer, so that the operation rule of information identification is simplified, and even when the large amount of information needs to be carried, the requirement can still be met in a low operation capacity mode.
In addition, to two-dimensional code discernment under the dim light environment, like the AGV through two-dimensional code navigation, install the camera in the AGV bottom usually, the AGV needs go to above the two-dimensional code, lets the camera be in directly over the two-dimensional code, and the two-dimensional code is under the dim light environment because back of the body AGV covers completely, can install the discernment that the LED light source is used for assisting the two-dimensional code usually. The invention further optimizes the design of the two-dimensional code reading device aiming at the situation, uses a plurality of monochromatic light sources to replace the filter lens 400, and can play the same role as the filter lens 400. When the monochromatic light source illuminates the two-dimensional code, the color and the white which are the same as the color of the light source are bright compared with other colors, the light source is regarded as white, and the other colors are regarded as black. When the two-dimensional codes with different colors need to be read, the lamp sources with different colors only need to be turned on once.
The working principle of the system is as follows: each color in the two-dimensional code can be screened through a specific filter lens 400 (or light source), each filter lens 400 (or light source) can filter one color except white, namely, through the filter lens 400 (or light source), the camera can only see the filter color of the filter lens 400 (or light source) and white, the filter color is bright, and is regarded as white, and other colors are dark, and are regarded as black. White is the reference color and is still visible to the camera after being filtered by any filter lens 400. After the red, yellow and green filter lenses 400 are passed, for the recognition software system, according to the installation sequence of the filter lenses 400, the three two-dimensional codes of a, b and c can be known to respectively correspond to red, yellow and green.
When larger information needs to be carried, the information can be classified by color, for example, two-dimensional code data of a class a, a subclass B, a data class C and a data class C correspond to final information, and the two-dimensional code information is also presented under the colors of a and B, the information can be further classified into a plurality of classes a1, a2, A3, …, B1, B2 and B3, so that the actually read data is C1 data of a B3 subclass under information of a2 class and C1 data of a B1 subclass under information of a2 class, and because the two subclasses B1 and B3 are different, even if the two-dimensional codes under a color and C color are consistent, different information is finally represented.
The method has great difference from the general meaning of classifying the two-dimensional code information through colors, and greatly increases the storage capacity and the classifiable capacity of the information. When the two-dimensional code needs to bear larger information, the method can greatly optimize the operation amount of the two-dimensional code, so that a computer with low cost and low operation capacity can meet the operation requirement.
Further, to the first step of two-dimensional code discernment, can increase specific colour or characteristic, if adopt infrared filter, scribble the material that has infrared reflection of light on four angles of two-dimensional code, at first under infrared filter attitude, fix a position the two-dimensional code position, later change other filters again, read the two-dimensional code information under the different colours. Furthermore, the reading sequence of the two-dimensional codes with different colors can be defined, and only the corresponding two-dimensional code information representing the reading sequence needs to be added under the infrared filter.
