Description of reference numerals: light source 1, without Apocynum cannabinum trump card 2, color sensor chip 3, with reference to color object 4, literal 2-1, back side 2-2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Invention mechanism of the present invention: as shown in Figure 2, the literal major part of existing mah-jong pieces is all white, and back side major part is all blue, yellow or green.This patent utilizes the literal and colouring discrimination back side of mah-jong pieces to realize the judgement without the literal and back side of Apocynum cannabinum trump card, thereby realization is without the function of magnetic mahjong machine.
According to trichromatic principle, any color can resolve into three kinds of colors of red, green, blue.The ratio difference of three kinds of blend of colors, can be combined into any color.Human eye can set the object of different colours, be because solar radiation after object, object only reflects its corresponding color.The light that we can utilize color sensor to detect object reflection is distinguished different colors, thereby has realized the judgement without the literal and back side of Apocynum cannabinum trump card.
As shown in Figure 1, this Color Recognition System without magnetic mahjong machine, this device comprises light source 1, without Apocynum cannabinum trump card 2 and color sensor chip 3, light source 1 coordinates with forming to irradiate without Apocynum cannabinum trump card 2, color sensor chip 3 is arranged near the light of coming for receiving diffuse reflection without Apocynum cannabinum trump card 2, by measuring the component of every kind of color of three primary colors in reverberation, calculate the color without measuring position on Apocynum cannabinum trump card 2, thereby judge the literal and back side without Apocynum cannabinum trump card 2.Irradiate at light source 1 with without Apocynum cannabinum trump card 2 between coordinating, be provided with transportable maybe can be blocked with reference to color object 4, for calculating this three primary colors parameter with reference to color object 4.
Color identification method without magnetic mahjong machine of the present invention, step is as follows: adopt color sensor chip 3 to receive from the light without diffuse reflection is come Apocynum cannabinum trump card 2, by measuring the component of every kind of color of three primary colors in reverberation, calculate the color without measuring position on Apocynum cannabinum trump card 2, judge the literal and back side without Apocynum cannabinum trump card 2 by the result of color.
In theory, the light that light source sends must be to cover all spectrum.That is to say, the trichromatic component of the light that light source sends must be completely equal, because if the trichromatic component of the light that light source sends is unequal, after reflection, the result of test just can not be accurately.In fact, do not cover the light source of all spectrum, there is no two identical light sources yet.And the parameter of each sensor chip also can not be identical.Result is, same testee, and in different color sensor systems, the result difference that sensor chip calculates.Like this, do not have reliable method to be just difficult to the reliable and stable of guarantee system.This patent be exactly in order to address this problem, make different systems draw identical result.
Because the literal major part of existing mah-jong pieces is all white, and there is the difference such as blueness, green at the back side.At every turn in the time of mahjong machine electrifying startup, first with reference to color object 4 (being generally white) as a benchmark, color sensor chip calculates this three primary colors parameter with reference to color object 4, and by the result store calculating in CPU; In the time of normal work, sensing system is by the parameter comparison of the measured parameter of reading and storage, and in the time that result is relatively in the error range of permission, tested object is with homochromy with reference to color object 4, otherwise is not just.Like this, no matter be to change light source, or sensor chip, as long as ensure the uniformity with reference to color object 4 as benchmark, just can ensure the reliability of test result.
As: in a certain color sensor system, the three primary colors parameter of reading as the white object of benchmark is respectively red 255, green 230, blue 220.By theoretical calculating, the result that this parameter draws is white certainly not, and white light should equate by each component, and red 255, green 255, blue 255.Meanwhile, the parameter that this white reference is read in each system can be not identical, and this is to cause because of light source, the inconsistent of chip.The in the situation that of batch production, can not debug separately each sensor.But we record after the parameter of this system, we just know the value of this system each color component in the time of white reverberation, have and the identical or approaching reverberation of stored parameter, and it be white for us just to know.Thereby reach the object that sets the literal and back side of mah-jong pieces.At this moment, light source and chip itself is not just so important, whether similar to benchmark be only important.Once the color of benchmark is wrong, just can not correctly judge the literal and back side of mah-jong pieces.
As a same reason, in the time changing the reverberation color of benchmark, we can change the literal color of mah-jong pieces.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
