In order to make the person skilled in the art better understand the solution of the present application, the technical solution of the embodiment of the present application will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1, a flowchart of an implementation of the dual-layer interpolation method according to the first embodiment of the present application is shown, and for convenience of explanation, only a portion relevant to the present application is shown.
The double-layer interpolation method comprises the following steps:
in step S101, an interpolation request carrying an original double-layered ionization chamber is received.
In the embodiment of the present application, the original double-layer ionization chamber refers to the original information of three-dimensional space rays obtained by probes distributed on the surface of an object to be measured, referring to the schematic tiling diagram of the double-layer ionization chamber shown in fig. 2, dark colors and light colors are respectively ionization chambers of an inner ring and an outer ring, and it is seen that the ionization chambers of the inner ring and the outer ring are distributed in a staggered manner, the ionization chamber of the outer ring is approximately located at the center of a square lattice point formed by the ionization chambers of the inner ring (because of the limitation of the hardware manufacturing process, the whole is actually offset by 0.1mm from the exact center, and the error is ignored here), and vice versa.
In the embodiment of the application, because the number of probes is quite limited, interpolation operation is needed to obtain the distribution of the dose on the surface of the object to be measured.
In step S102, a filling operation is performed on the boundary of the original double-layer ionization chamber, so as to obtain a filled double-layer ionization chamber.
In the embodiment of the application, the ionization chambers are distributed on the surface of the object to be measured, and the periodicity is considered in interpolation, and in addition, the interpolation needs to use the values of points in a certain range near the point to calculate the difference value, so that the boundary of the original double-layer ionization chamber is filled.
In the embodiment of the application, the filling operation can be to perform periodic filling operation on the horizontal boundary of the double-layer ionization chamber according to periodic data to obtain a periodic filling double-layer ionization chamber; and repeatedly filling the vertical boundary of the periodically filled double-layer ionization chamber according to boundary data to obtain the filled double-layer ionization chamber.
In step S103, diagonal interpolation operation is performed on the second filled ionization chamber of the filled double-layer ionization chamber according to the first filled ionization chamber of the filled double-layer ionization chamber in the diagonal direction, so as to obtain an intermediate double-layer ionization chamber.
In the embodiment of the application, the first filling ionization chamber and the second filling ionization chamber are opposite and respectively refer to the inner layer and the outer layer in the double-layer ionization chamber.
In the embodiment of the application, the diagonal interpolation operation may be to calculate a first diagonal difference of the first filling ionization chamber in a diagonal direction; calculating a second diagonal interpolation weight of the second filling ionization chamber according to the first diagonal difference; performing diagonal interpolation operation on the second filling ionization chamber according to the second diagonal interpolation weight; calculating a second diagonal difference of the second filling ionization chamber in the diagonal direction; calculating a first diagonal interpolation weight of the first filling ionization chamber according to the second diagonal difference; and performing diagonal interpolation operation on the second filling ionization chamber according to the first diagonal interpolation weight to obtain the middle double-layer ionization chamber.
In an embodiment of the present application, the diagonal interpolation operation is expressed as:
Wherein w Pj represents the weight coefficient of the point to be interpolated P and the known point j; p j represents the known reading at point j; e is a small amount to avoid 0.
In step S104, a horizontal-vertical interpolation operation is performed on the intermediate double-layer ionization chamber in the horizontal-vertical direction, to obtain a resultant double-layer ionization chamber.
In the embodiment of the application, the horizontal-vertical interpolation operation can be to calculate the first horizontal-vertical difference of the first middle ionization chamber of the middle double-layer ionization chamber in the horizontal-vertical direction; calculating a first horizontal-vertical interpolation weight of the first intermediate ionization chamber according to the first horizontal-vertical difference;
Performing horizontal-vertical interpolation operation on the first middle ionization chamber according to the first horizontal-vertical interpolation weight; calculating a second horizontal-vertical difference of a second middle ionization chamber of the middle double-layer ionization chamber in the horizontal-vertical direction; calculating a second horizontal-vertical interpolation weight of a second intermediate ionization chamber according to the second horizontal-vertical difference; and performing horizontal-vertical interpolation operation on the second middle ionization chamber according to the second horizontal-vertical interpolation weight to obtain a result double-layer ionization chamber.
In step S105, a cancellation operation is performed on the resultant double-layer ionization chamber, resulting in a cancellation double-layer ionization chamber.
In the embodiment of the application, after one round of interpolation is completed, the filled rows and columns are removed, and then the next round of interpolation is performed.
In step S106, it is determined whether the cancellation-compensation double-layer ionization chamber satisfies a preset resolution requirement.
In the embodiment of the application, the user can adjust the preset resolution requirement according to the actual situation.
In step S107, if the cancellation-compensation double-layer ionization chamber satisfies the resolution requirement, the cancellation-compensation double-layer ionization chamber is output.
In step S108, if the resolution requirement is not satisfied by the two-layer cancellation ionization chamber, the filling operation, the diagonal interpolation operation, the horizontal-vertical interpolation operation, and the cancellation operation are repeatedly performed until the resolution requirement is satisfied by the two-layer cancellation ionization chamber, and the two-layer cancellation ionization chamber is output.
In the embodiment of the application, the method is inversely multiplexed to the gradient (difference) between the points, and the difference value between the adjacent points can be calculated first for simplifying calculation, and the time for use is required to be called. And repeated calculation is avoided, and the speed is increased.
In the embodiment of the application, the original single-layer resolution is doubled by successfully utilizing the information of another layer of ionization chamber. The steps can be repeated further to increase the resolution of the single layer, only because the inner and outer layer lattice points are not staggered any more at this time, only the single layer interpolation is performed, q in the step S103 is replaced by p, or the second method of the reference step S104 is referred to, and values of centers of A, B1, I1 and M are required to be set, and then |p A-pM | and the values of centers of M are comparedThe smaller one is selected, and the average is calculated.
In the embodiment of the application, the resolution is doubled every time the method is repeated, and the coordinates of the interpolation points are relatively fixed. The general interpolation method can calculate the value of any point, but the method cannot. After the resolution reaches the requirement, the method can be replaced by a general interpolation method such as linear interpolation and the like, and flexible processing is realized.
In the embodiment of the application, the application is not limited to the surface of a cylinder, and any interpolation problem of double-layer staggered distribution can be referred to the method.
In an embodiment of the present application, a dual-layer interpolation method is provided, including: receiving an interpolation request carrying an original double-layer ionization chamber; filling the boundary of the original double-layer ionization chamber to obtain a filled double-layer ionization chamber; performing diagonal interpolation operation on a second filled ionization chamber of the filled double-layer ionization chamber in the diagonal direction according to a first filled ionization chamber of the filled double-layer ionization chamber to obtain an intermediate double-layer ionization chamber; performing horizontal and vertical interpolation operation on the middle double-layer ionization chamber in the horizontal and vertical directions to obtain a result double-layer ionization chamber; performing a compensation operation on the result double-layer ionization chamber to obtain a compensation double-layer ionization chamber; judging whether the cancellation and compensation double-layer ionization chamber meets a preset resolution requirement or not; outputting the cancellation and compensation double-layer ionization chamber if the cancellation and compensation double-layer ionization chamber meets the resolution requirement; if the resolution requirement is not met by the cancellation double-layer ionization chamber, repeating the filling operation, the diagonal interpolation operation, the horizontal and vertical interpolation operation and the cancellation operation until the resolution requirement is met by the obtained cancellation double-layer ionization chamber, and outputting the cancellation double-layer ionization chamber. The application fully utilizes the distribution characteristics of arcmap double-layer ionization chambers, applies the information of another layer to assist single-layer interpolation, and utilizes gradient information to overcome the problem of large error of algorithms such as linear interpolation in large gradient areas. And the calculation is relatively simple and convenient, and the speed is high.
With continued reference to FIG. 3, a flowchart of one embodiment of step S102 of FIG. 1 is shown, only those portions relevant to the present application being shown for ease of illustration.
In some optional implementations of the present embodiment, step S102 specifically includes:
in step S301, a period filling operation is performed on the horizontal boundary of the double-layer ionization chamber according to the periodic data, so as to obtain a period filled double-layer ionization chamber.
In step S302, the vertical boundary of the periodically filled double-layer ionization chamber is repeatedly filled according to the boundary data, so as to obtain the filled double-layer ionization chamber.
In the embodiment of the application, the points with the range larger than or equal to the left and right boundaries of fig. 2 are filled with periodic boundary conditions. If the range is 1, the left and right are filled in a row.
In the embodiment of the present application, the upper and lower boundaries of fig. 2 are padded with points equal to or greater than the range, and the padding rule is a value of the duplicate boundary.
With continued reference to fig. 4, a flowchart of one embodiment of step S103 of fig. 1 is shown, only the portions relevant to the present application being shown for ease of illustration.
In some optional implementations of the present embodiment, step S103 specifically includes:
In step S401, a first diagonal difference of the first padded ionization chamber in a diagonal direction is calculated.
In step S402, a second diagonal interpolation weight of a second padded ionization chamber is calculated from the first diagonal difference.
In step S403, a diagonal interpolation operation is performed on the second padded ionization chamber according to the second diagonal interpolation weight.
In step S404, a second diagonal difference of the second padded ionization chamber in the diagonal direction is calculated.
In step S405, a first diagonal interpolation weight of the first padded ionization chamber is calculated from the second diagonal difference.
In step S406, diagonal interpolation is performed on the second filled ionization chamber according to the first diagonal interpolation weight, so as to obtain an intermediate double-layer ionization chamber.
In an embodiment of the present application, all interpolation algorithms can be formally written as:
Where p i,pj is the value at point i, j and w ij is a coefficient, so interpolation of a point i is a weighted average of the values of other known points j. In general, the closer to i the point, the greater its weight. A range may be set, and points outside the range may be set as weights w to 0. As an example, referring to the diagonal interpolation diagram shown in fig. 5, if the deep color points are all known points, the point P is interpolated, and if the range is set to 2, the values of 16 points (all the deep color points in fig. 5) of size 4*4 around P are weighted averaged; if the range is taken to be 1, the values of the four points are taken E, F, J, K for calculation. For simplicity, the following discussion is for a range of 1, it being understood that the examples of interpolation herein are for ease of understanding only and are not intended to limit the application.
In the embodiment of the application, the center position of the square lattice point of the inner ring is interpolated by means of the ionization chamber information of the outer ring. As in fig. 5, now to interpolate point P, it is necessary to determine E, F, J, K the weights of the four points. In order to solve the problem of boundary blurring, the general idea is that the local weight with small gradient is large and the local weight with large gradient is small. The outer ring point P and surrounding points (light color points in fig. 5) position readings are known and can be used to approximate the gradient at the inner ring point P. The application, we take the following form of weights:
Where q is the value of the point on the outer ring and e is a small amount to avoid 0, preferably 10 -10. After the weights are obtained, the value of the point P can be expressed as:
where e is a small amount to avoid 0. The denominator is to normalize the weights.
With continued reference to fig. 6, a flowchart of one embodiment of step S104 of fig. 1 is shown, only the portions relevant to the present application being shown for ease of illustration.
In some optional implementations of the present embodiment, step S104 specifically includes:
In step S601, a first horizontal-vertical difference in the horizontal-vertical direction of a first intermediate ionization chamber of the intermediate double-layer ionization chamber is calculated.
In step S602, a first horizontal-vertical interpolation weight of the first intermediate ionization chamber is calculated from the first horizontal-vertical difference.
In step S603, a horizontal-vertical interpolation operation is performed on the first intermediate ionization chamber according to the first horizontal-vertical interpolation weight.
In step S604, a second horizontal-vertical difference in the horizontal-vertical direction of a second intermediate ionization chamber of the intermediate double-layer ionization chamber is calculated.
In step S605, a second horizontal-vertical interpolation weight of the second intermediate ionization chamber is calculated from the second horizontal-vertical difference.
In step S606, performing horizontal-vertical interpolation on the second intermediate ionization chamber according to the second horizontal-vertical interpolation weight, to obtain a resultant double-layer ionization chamber.
In the embodiment of the present application, as shown in the schematic diagram of horizontal-vertical interpolation in fig. 7, the values of the inner ring deep color point and the shallow color point are known, and the white point is interpolated. Taking point M1 as an example, the point of range 1 is E, J, O, P. The steps S601 to S603 are simulated, the gradients in the four directions of up, down, left and right are considered, and weights are calculated:
alternatively |p E-pJ | and |p O-pP | can be compared, the small ones selected, averaged, i.e.:
in summary, the present application provides a dual-layer interpolation method, including: receiving an interpolation request carrying an original double-layer ionization chamber; filling the boundary of the original double-layer ionization chamber to obtain a filled double-layer ionization chamber; performing diagonal interpolation operation on a second filled ionization chamber of the filled double-layer ionization chamber in the diagonal direction according to a first filled ionization chamber of the filled double-layer ionization chamber to obtain an intermediate double-layer ionization chamber; performing horizontal and vertical interpolation operation on the middle double-layer ionization chamber in the horizontal and vertical directions to obtain a result double-layer ionization chamber; performing a compensation operation on the result double-layer ionization chamber to obtain a compensation double-layer ionization chamber; judging whether the cancellation and compensation double-layer ionization chamber meets a preset resolution requirement or not; outputting the cancellation and compensation double-layer ionization chamber if the cancellation and compensation double-layer ionization chamber meets the resolution requirement; if the resolution requirement is not met by the cancellation double-layer ionization chamber, repeating the filling operation, the diagonal interpolation operation, the horizontal and vertical interpolation operation and the cancellation operation until the resolution requirement is met by the obtained cancellation double-layer ionization chamber, and outputting the cancellation double-layer ionization chamber. The application fully utilizes the distribution characteristics of arcmap double-layer ionization chambers, applies the information of another layer to assist single-layer interpolation, and utilizes gradient information to overcome the problem of large error of algorithms such as linear interpolation in large gradient areas. And the calculation is relatively simple and convenient, and the speed is high.
It should be emphasized that, to further ensure the privacy and safety of the above described cancellation-double ionization chamber, the above described cancellation-double ionization chamber may also be stored in a node of a blockchain.
