The tolerance of the X axis, the tolerance of the Y axis and the tolerance of the Z axis are respectively expressed as delta X, delta Y and delta Z, if delta X is larger than delta X, the deviation of the actually measured X coordinate of the positioning hole is considered to be unqualified, and if delta X is not larger than delta X, the deviation of the actually measured X coordinate of the positioning hole is considered to be qualified. The definition of Y-axis and Z-axis is similar.
S40: correcting the deviation result by a matrix transformation solving method according to the target hole group, and obtaining a target coordinate of the target hole;

in the specific implementation process, the target hole group is formed by grouping four positioning holes, the positioning holes in the target hole group are target holes, the positioning holes are process positioning holes which are defined according to a theoretical digital-analog or set independently according to actual needs, the positioning hole data should include actual position information, normal vector information and connecting piece information, and the actual position information represents the actual position of the hole; the method comprises the steps that the normal vector information represents the normal vector information coincident with the axis of a hole, the method is matched with a digital assembly system hole making device for use, a positioning hole photographing and identifying system and a data system are mounted on an end effector of the method, the position information of the positioning hole can be identified and output in a coordinate mode, and corresponding data can be stored or adjusted and modified by an operator; the connecting piece information represents the connecting pieces to be connected at the hole-making positions, the connecting mode, the connecting strength and other information in the manufacturing process of the closed structure of the aircraft, and is used for guiding the assembling work.
S101: identifying the positioning holes, numbering the positioning holes, and obtaining first positioning holes;

in the specific implementation process, the collected positioning hole data is analyzed and processed and divided to form target hole groups, and in the actual situation, the deviation along the axis direction of the positioning hole does not affect the hole position, so that except for the axis direction, the axis direction is set to be a Z axis by only comparing the directions on the surface of the external application part, the X axis and the Y axis correspond to a first direction and a second direction, the plane where the two directions are located is the surface of the external application part, and the numbers of the target holes in one group of target hole groups are recorded as P1, P2, P3 and P4, so that the subsequent correction can be performed by utilizing matrix transformation.
In one embodiment, after comparing the coordinate difference of the target hole with the calibration coordinate tolerance and obtaining the deviation result, the hole making method further comprises:
obtaining a deviation target hole according to the deviation result; wherein the deviation target holes are unqualified target holes in the target hole group.
In the specific implementation process, the deviation result includes all comparison results of the coordinate difference and the calibration coordinate tolerance, including the conditions of passing and failing, and for the passing difference, the corresponding coordinate deviation is not required to be corrected, so in this embodiment, the coordinate deviation is screened to obtain a deviation target hole, that is, a deviation-failing target hole in the target hole group.
Correspondingly, according to the target hole group, correcting the deviation result by a matrix transformation solving method, and obtaining the target coordinates of the target hole, the method comprises the following steps:
and correcting the deviation result by a matrix transformation solving method according to the target hole group and the deviation target hole, and obtaining the target coordinates of the target hole.
In one embodiment, since the number of the target holes in the target hole group is four, the number of the target holes with unqualified deviation is zero to four, and for the case that no target hole has deviation, no correction is obviously needed, and the subsequent steps are directly executed according to the situation; when the number of target holes with unqualified deviation is four, obviously, the unqualified target holes are not used as supports to correct the target holes, and even if the target holes can be corrected, all the target holes are identified and then corrected, the process is more complicated, and the process is not as simple as directly re-determining and recognizing all the target holes.
Therefore, the embodiments of the present application specifically describe the correction manner when the number of target holes with the deviation being not qualified is one, two, and three. Specifically, from the deviation results, the deviation target hole is obtained:
when the number of the deviation target holes is one:
correcting the deviation result by a matrix transformation solving method according to the target hole group and the deviation target hole, and obtaining the target coordinates of the target hole, wherein the method comprises the following steps:
acquiring the actual measurement coordinates of each target hole in the target hole group according to the target hole group;
obtaining a deviation coordinate of the deviation target hole according to the deviation target hole; the deviation coordinates are measured coordinates of the deviation target hole, and the coordinate difference is larger than the coordinates corresponding to the calibration coordinate tolerance;

and obtaining the target coordinates of the target hole according to the result of correcting the deviation result.
In the specific implementation process, when any target hole is unqualified in deviation, the deviation coordinate needs to be obtained according to the coordinate judgment of the deviation target hole, namely the deviation unqualified is generated in which coordinate, and after the judgment is finished, other three points can be used for correction; there are two cases of an unacceptable deviation: the first is that the coordinate on only one coordinate axis is unqualified; the second is that the coordinates on both axes are not qualified. It should be noted that, since the qualification of the deviation on the Z axis does not affect the hole making, the determination of the deviation target hole number in this embodiment is based on the X axis and the Y axis.
For the first condition, the actual measurement coordinates corresponding to the qualified hole sites are utilized, other parameters are kept unchanged, and matrix transformation is used for solving so that the coordinate deviation of the target holes with unqualified deviation meets the condition that the coordinate deviation is not greater than the calibration tolerance; and in the second case, the parameters of the two coordinate axes are respectively corrected according to the correction method in the first case.
In one embodiment, the number of deviation targets is two:
according to the target hole group and the deviation target hole, the deviation result is corrected by a matrix transformation solving method, and before the target coordinate of the target hole is obtained, the hole making method further comprises the following steps:
judging whether the deviation target holes are positioned in the same coordinate axis direction or not and whether the actual measurement coordinates with unqualified deviation are positioned in different coordinate axis directions or not, and obtaining a judgment result;

and correcting the deviation result by a matrix transformation solving method according to the target hole group, the deviation target hole and the judgment result, and obtaining a target coordinate of the target hole.
In the specific implementation process, reference may be made to the composition of a rectangle, if only two points located on the same side exist, it is impossible to determine the uniquely determined rectangle, and therefore, when the number of target holes with unqualified deviation is two, it is necessary to determine whether the target holes with the deviation are located in the same coordinate axis direction, and whether the measured coordinates with unqualified deviation are located in different coordinate axis directions, if the determination result of determining whether the target holes with the deviation are located in the same coordinate axis direction is yes, and if the determination result of determining whether the measured coordinates with unqualified deviation are located in different coordinate axis directions is no, it is impossible to correct, and only positioning and identification can be performed again.
If the judgment results are yes, the two target holes can be subjected to matrix transformation, in a simple way, the diagonal line of the rectangle is determined, the only rectangle can be determined, and then the matrix transformation solution is correspondingly executed according to the target hole group, the deviation target holes and the judgment results to correct the deviation results, and the target coordinates of the target holes are obtained.
If the judgment result of judging whether the deviation target holes are positioned in the same coordinate axis direction is negative;
correcting the deviation result by a matrix transformation solving method according to the target hole group, the deviation target hole and the judgment result, and obtaining a target coordinate of the target hole, wherein the method comprises the following steps:
and correcting the deviation result by a matrix transformation solving method according to the target hole group, the positioning hole adjacent to the target hole group in the adjacent hole group, the deviation target hole and the judgment result, and obtaining the target coordinate of the target hole.
If two points in different directions are unqualified, hole site information meeting matrix transformation can be formed by using adjacent P5 and P6 hole sites, and matrix transformation solving and correction is carried out.
In one embodiment, when the number of the deviated target holes is three, based on the matrix transformation solving and correcting, one hole site in the target hole group is corrected, the hole site must be in a form capable of forming a three-point correcting point with the adjacent hole sites, and on the basis, two hole sites in the target hole group are re-identified, so that the correction of all the target holes in the target hole group is completed.
In an embodiment, the number of the target holes in the target hole group may be more than four, and it is ensured that at least four point locations may be subjected to matrix transformation solution to complete correction, and for a large number of target holes, if the number of the holes with qualified deviation exceeds eighty percent and the deviation is less than half of the tolerance, other unqualified holes may not be corrected, and the correction is performed according to the theoretical holes.
In one embodiment, after the hole site information of the hole is corrected by a four-point correction method according to the target coordinates of the target hole, the hole making method further includes: and regenerating the identification program according to the corrected result, and simulating by using off-line programming software or simulation software. So as to check and verify the performability and the safety of the program.
