s6.3: and a laser scanner is utilized to obtain a local 3D model of the reinforcing rib, and the aluminum template is subjected to characteristic coding through a computing platform of an industrial personal computer 5.
When this embodiment is implemented, because the plate type is different, its strengthening rib also respectively is different, and the data characteristics of Pa plate roof are: the outline of the reinforcing rib of the plate is obvious, the outline of the reinforcing rib is 25cm, the height of the reinforcing rib is flush with the height of the plate, and the two sides of the plate are free of angle aluminum; the data characteristics of the Pb plate wall template are as follows: the outline of the reinforcing rib of the plate is obvious, the width of the reinforcing rib is 50cm, the height of the reinforcing rib is not parallel to the height of the plate, and double-side angle aluminum is arranged on two sides of the plate; the data characteristics of S plate wall end plate (K board) do: the plate strengthening rib profile is obvious with non-strengthening rib profile, and the strengthening rib width is 50cm and highly and plate height not parallel and level, and there is unilateral angle aluminium plate both sides. The data characteristics of the plate beam side template are as follows: the outline of the reinforcing rib and the outline of the non-reinforcing rib of the plate are obvious, the width of the reinforcing rib is 30cm, the height of the reinforcing rib is flush with the height of the plate, and double-angle aluminum is arranged on two sides of the plate; the data characteristic of Fh panel is: the plate strengthening rib profile is obvious with non-strengthening rib profile, and the strengthening rib width is 20cm and highly and the high parallel and level of plate, and plate angle aluminium portion profile line characteristic is obvious, and there is unilateral angle aluminium plate both sides.
According to the scheme, the obtained characteristic value of the plate is compared with the characteristic value of the plate with the corresponding model, the binary code corresponding to each plate is obtained, and the corresponding binary code sequence is formed. Aiming at different differences of different plate pieces among codes, a unique corresponding binary code sequence of the plate piece can be established. And matching the binary code sequence corresponding to each plate with the preset 6 binary code sequences, and when the matching is successful, determining that the plate has the target characteristic at the position corresponding to the target area, thereby determining the type of the plate.
Specifically, the matching module in the scheme only needs to use a five-bit binary code to perform matching judgment. And according to the coding rule described in S6.3, when the plate is scanned by the laser profiler to extract the characteristic information, obtaining a group of five-bit binary coding sequences. Binary coding sequence x of plate to be tested4′x3′x2′x1′x0Subtracting the coded sequences of the five types of plate pieces respectively, taking an absolute value, and when the calculated result is 00000, considering that the plate piece to be detected belongs to the type matching success.
x4′x3′x2′x1′x0′-x4x3x2x1x0＝00000
And after the plate is successfully matched, the plate is not subjected to sequence subtraction absolute value calculation with binary codes of other remaining types of plates, so that the plate to be detected can be classified in a matching way by judging the type of one plate at least once and judging at most five times, and the plate to be detected is determined to be matched with the preset plate type. The method and the system realize accurate identification of the target plate, improve identification efficiency and save manpower, material resources and time.
S6.3, when the characteristic coding is carried out on the aluminum template, the method comprises the following steps:
s6.3.1: judging the width value of the reinforcing ribs of the plate;
considering that the laser scanner may have errors in the calculation of the width of the plate, setting the width value of the plate to be a range in the coding rule, wherein the range is set to have an error of one centimeter in absolute value with the width value of each type of plate, and then judging the width value of the reinforcing rib of the plate; if the width is 24-26 cm, encoding it as x4x3When the width is 38-42 cm, the code is x 014x3When the width is 54-56 cm, the code is x when the width is 104x311; if the width of the plate does not fall within the ranges, the plate is coded as x4x3＝00；
S6.3.2: judging whether the plate has an extension part or not, if not, coding the plate as x2x1With 01, only the single stretch is coded as x2x110, with a double stretch coded as x2x1＝11；
S6.3.3: judging whether the height of the reinforcing ribs of the plate is flush with the plate or not; if so, it is encoded as x0Otherwise, x is coded as0＝0。
In this embodiment, since the 6 plate members are different from each other, the classification is performed according to the respective characteristics of the plate members. After the plate to be detected passes through the characteristic value judgment condition, the binary code corresponding to each plate is obtained to form a corresponding binary code sequence.
Specifically, according to the coding rule stated in S6.3, binary coding sequences of 6 plate members can be obtained. Wherein, the code of the Pa plate can be expressed as: x is the number of4x3x2x1x010011; the code of the Pb pieces can be expressed as: x is the number of4x3x2x1x011110; the coding of the S plate may be expressed as: x is the number of4x3x2x1x011100; the coding of the D-plate may be expressed as: x is the number of4x3x2x1x010111; the code for the Fh plate may be expressed as: x is the number of4x3x2x1x001101. The coding of the profiled sheet may be expressed as: x is the number of4x3x2x1x000011 for the above coding rule, the coding of each plate is unique and corresponding.
Considering that in the actual identification process of the scheme, other false identification conditions such as back plate rib false identification and the like caused by other environmental problems such as the cement cleaning of the plate is not in place or the laser profilometer is influenced by light rays and the like are possible, when the plate code is not matched with the preset code, the plate to be detected has already finished the operation of taking the absolute value by the quintic binary subtraction method, and a new group of binary coding sequences is obtained, and because no matching type plate exists, the explained difference sequence result is not an ideal 00000 coding sequence. And when the number of the '1' in one group of binary coding sequences is 1, the plate is considered to be a preset plate which is correspondingly subtracted from the plate to obtain an absolute value to obtain the difference binary coding sequence, if the number of the '1' is not 1, the plate is judged to be an opposite plate, and matching classification is finished.
The specific operation steps for encoding the binary sequence whose operation result is not all 00000 are as follows: and (3) performing AND operation from the highest bit of the coding sequence to '1', if the operation result is '1', counting and adding 1, then shifting and continuing operation until the last bit jumps out of the cycle, obtaining the number of '1' from the obtained output counting result, and when the number of the output 1 is 1, stopping judgment operation and judging that the plate belongs to the type of the plate corresponding to the differential binary coding sequence participating in AND operation at this time.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
