This optical identification image 100 is to be made up of 10 of a plurality of optical identification codes; See also Fig. 1 to Fig. 3, the optical identification code 10 of present embodiment is to be that example is explained with a kind of OID sign indicating number wherein, and is as shown in Figure 2; The OID sign indicating number is the permutation and combination through a plurality of small picture points 11 in inside; Discharging 4096 different optical identification codes, and then can be picked out 4096 different store informations, can join TaiWan, China equally about the detailed principle of OID sign indicating number and invent the I235926 patent by optical identification device 200.
Please consult Fig. 1, Fig. 3 again, in present embodiment, said optical identification code 10 is on light surface of contact 101, to be printed as two-dimensional array A2 with suitable printed resolution; This two-dimensional array A2 is made up of a plurality of identical vertical one-dimensional array A1; In this one-dimensional array A1, be to be arranged to many 4096 different optical identification codes 10, each optical identification code 10 is represented a metrical information (in the present embodiment preliminary information that to be optical identification device 200 taken out from this optical identification code 10 respectively) respectively; This metrical information is digital code in present embodiment; Be for the integer between 0 to 4095, as shown in Figure 3, and the arrangement of said optical identification code 10 on this light surface of contact 101; It is digital code ordering according to correspondence; Present embodiment is from 0 arranging continuously to 2800 (quantity be look scalable maximum length and decide), and adjacent two optical identification codes 10 are to adopt continuous row sign indicating number, between do not have the interval; So far, promptly complete and can be applicable to the optical identification image 100 that length measures.The optical identification image 100 of below putting off until some time later bright present embodiment can be used for principle and the practical operation that length measures:
Respectively this optical identification code 10 has a height H and a width W, and at this wherein a kind of OID sign indicating number that illustrates, its true altitude is 0.423mm, and width is 0.508mm.And the digital code of each optical identification code 10 is to point to a pair of length numerical value of answering, in present embodiment, and the product of the digital code of height H that this length numerical value is optical identification code 10 and correspondence thereof, and this calculating is to be carried out by optical identification device 200.For instance; The digital code of the rightmost optical identification code 10 of secondary series is 1; Its length numerical value is 1*0.423, is to equal 0.423mm, and the optical identification device 200 of present embodiment is to be set at three bit value behind the radix point of this length numerical value more than or equal to 0.250mm as the carry benchmark; Therefore, 0.423mm is 0.5mm after carry; In like manner, digital code is 2800 optical identification code, and the length numerical value of its sensing is 2800*0.423 (being 1184.4mm) (being 1184.5mm) after carry; Hence one can see that; The said optical identification code 10 of the optical identification image 100 of present embodiment is to arrange according to its corresponding length numerical value, and precision reaches 0.5mm, and via the rough physical length that equals of the length numerical value that is drawn behind the optical identification; And this error measures as being applied to height, is permissible.
More than be the principle illustration that the optical identification image applications measures in length, what only must explain is that above-mentioned size and quantity only illustrate, not as limit.For instance, be 0.5mm just if any the height of another kind of optical identification code, the optical identification image that then institute's construction goes out behind row's sign indicating number continuously, the length numerical value measured through the optical identification device will equal physical length.
Again, between the said metrical information ordinal relation might not be arranged, also can be random number and arrange, as long as have corresponding length numerical value in the optical identification device.
Person very, the metrical information of above-mentioned optical identification code also can directly store into the form of length number value in advance, does not need to calculate through product again.
Please cooperate Fig. 4 again, during actual the use, optical identification image 100 is can be printed in earlier on the transparent base 300; Thereafter this transparent base 300 affixes to wall 400 workplaces such as grade again; And will to be printed on digital code be to align with ground 500 in transparent base 300 bottoms 301 of 0 optical identification code, and thus, the user only needs optical identification device 200 is pressed against the crown; And make the front end conflict or, so can record user's height near this transparent base 300; And because it is all identical to be positioned at the optical identification code 10 of same row in the optical identification image 100, therefore, so long as measure in same at, numerical value all can be identical, as far as the user, uses more convenient and simple and easy.
Even the present invention can further be made into the optical identification image 100 ' of measurement length and width simultaneously, and is as shown in Figure 5; The metrical information of each optical identification code 10 ' can be endowed and include X value and Y value (i.e. (X; Y)) two-digit code reads for the optical identification device, and with the Y of the optical identification code 10 ' that the reads height H that goes up on duty; The X width W that goes up on duty; The carry computation of selectively being scheduled to afterwards obtaining this optical identification code 10 ' width numerical value and length numerical value pointed, thereby need to can be applicable to the device of measurement length and width simultaneously.Certainly, above-mentioned X value and Y value also can directly store into the form of width numerical value and length numerical value respectively in advance, do not need to calculate through product again.
In addition, because the OID sign indicating number is prone to ignore for visual inspection, very having needs electron microscope to observe, and adds that it is to be printed on the transparent base 300, therefore can't destroy the outward appearance of wall 400 workplaces such as grade.
Certainly, this transparent base 300 also can be attached at existing wall height chi (figure do not show), does not observe and both deposits pattern and scale on this height chi and can not have influence on the user, to reach the measurement of physics and electronics simultaneously.Certainly, the OID sign indicating number also can be printed on nontransparent base material.
From the above; But present embodiment utilizes the function of optical identification code recorded information; Again through selecting existing or make the optical identification code of new suitable length metering, and give the length numerical value that each optical identification code points to a correspondence, and according to the said optical identification code of the series arrangement of length numerical value; Construction goes out to imitate the optical identification image of rule thus; And can arrange in pairs or groups with the optical identification device, construction goes out the length measurement system of an applied optics identification, and then is implemented in the application of measurement length.Compare existing person, the invention provides a kind of length measurement system and method not seen before, and reach by optical identification code that can store information because be; Therefore; Optical identification device of the present invention switching on and shutting down are at any time used, and do not need to make zero again, and are quite convenient in the use; Moreover no matter user's fast moving optical identification device how as long as be to be anchored on the optical identification pattern at last, all can show correct value.
Other what deserves to be mentioned is, makes the optical identification image of the measurement precision that is different from the foregoing description like desire, be can identical optical identification code is neighbour to arrange, and the quantity of neighbour identical optical identification sign indicating number is many more, and precision is just low more.For instance; The ordering of optical identification code 10 in one-dimensional array A1 like above-mentioned embodiment; Follow digital code is 0,0,1,1 instead ... 2800,2800 series arrangement, then the measurement precision of the optical identification image that goes out of construction will change to 1mm from 0.5mm, and other is by that analogy.Thus, can increase design freedom of the present invention and range of application.
Again, adjacent two optical identification codes 10 of the foregoing description also can so also can be adjusted precision in being provided with at interval between the two; And, if it is optical identification code is to select one-dimensional bar code or two-dimensional bar for use, as shown in Figure 6; Then between adjacent two bar codes 20 interval 30 must be set usually; Therefore need to cooperate special optical identification device, for example: have the optical identification device of two optical image-taking heads, but or other identification and filtering optical identification device at interval.In addition, bar code 20 equally can be by being endowed the metrical information of length number value should be arranged, and said bar code 20 also sorts according to length numerical value, promptly can be applicable to the measurement of length.
Except that above-mentioned illustration, the present invention more can be applicable to bendable height chi 600 shown in Figure 7.Show though this measure meeting causes the optical identification code 10 on the optical identification pattern 100 when using, to be on-plane surface, but still be and to read by optical identification device (figure does not show) institute's identification, this point be known capacitance formula digital encoder can't reach.
In addition; The present invention also can be applicable to telescopic type electronics body height measuring device 700 shown in Figure 8; In detail; Optical identification pattern 100 can be through being printed in interior chi 701 surfaces that are pasted to body height measuring device 700 on the base material 300 more earlier, and optical identification device 200 is integrated into control panel 702, so can reach the purpose that measures height equally.
