[0002] In the field of machine vision, a commonly used machine vision camera interface standard is the Gigabit Ethernet Vision Standard (GigE Vision) protocol. The Gigabit Ethernet Vision Standard protocol consists of two parts: the Gigabit Ethernet Vision Streaming Protocol (GVSP) and the Gigabit Ethernet Vision Control Protocol (GVCP), which are used in scenarios with extremely high real-time requirements. Usually, when the network card receives a GVSP protocol message, the network card sends the GVSP message to the CPU software for framing processing, and combines the contents of multiple GVSP messages belonging to an image into one image frame.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention. The terms used in the implementation mode of the present invention are only used to explain the specific embodiments of the present invention, and are not intended to limit the present invention.

[0024] See also Figure 1 , Figure 1 This is a flow chart of a verification message generation method provided by this application. Figure 1 As shown, the verification message generation method of the present application includes: S101: A computing device generates a first matrix.

[0025] The first matrix includes a plurality of matrix columns, for example, a first matrix column and a second matrix column. The first matrix corresponds to a first image frame, and the first image frame may include a plurality of image slices, for example, the first image frame may include 64 image slices, may include 128 image slices, etc., which are not specifically limited here.

[0026] The following description will be made by taking the first matrix column and the second matrix column as examples.

[0027] The first matrix column includes a first discard start element, a first discard end element, a first retransmission start element, a first retransmission end element, and a first fragmentation number element.

[0028] The first discard start element is used to indicate the first discard start sequence number of the image slices to be discarded in the first image frame. Therefore, according to the first discard start sequence number and the first discard end element, it is possible to determine which image slices in the first image frame are to be discarded.

[0029] The first retransmission start element is used to indicate the first retransmission start sequence number of the image slice that needs to be retransmitted in the first image frame. The first retransmission end element is used to indicate the first retransmission end sequence number of the image slice that needs to be retransmitted in the first image frame. Therefore, according to the first retransmission start sequence number and the first retransmission end element, it is possible to determine which image slices in the first image frame are to be retransmitted. Since only the discarded image slices need to be retransmitted, the interval formed by the first retransmission start element and the first retransmission end element belongs to the interval formed by the first discard start element and the first discard end element. Here, belonging means that the interval formed by the first retransmission start element and the first retransmission end element is equal to the interval formed by the first discard start element and the first discard end element, or the interval formed by the first retransmission start element and the first retransmission end element is smaller than the interval formed by the first discard start element and the first discard end element.

[0030] The first number of slices element is used to indicate the number of image slices in the first image frame. The first discard start element, the first discard end element, the first retransmission start element, and the first retransmission end element are all smaller than the first number of slices element.

Therefore, according to the second discard start sequence number and the second discard end element, it is possible to determine which image slices in the first image frame are to be discarded.

[0033] The second retransmission start element is used to indicate the second discard start sequence number of the image slices that need to be retransmitted in the first image frame, and the second retransmission end element is used to indicate the second discard end sequence number of the image slices that need to be retransmitted in the first image frame. Therefore, according to the second retransmission start sequence number and the second retransmission end element, it is possible to determine which image slices in the first image frame are to be retransmitted. Since only the discarded image slices need to be retransmitted, the interval formed by the second retransmission start element and the second retransmission end element belongs to the interval formed by the second discard start element and the second discard end element. Here, belonging means that the interval formed by the second retransmission start element and the second retransmission end element is equal to the interval formed by the second discard start element and the second discard end element, or the interval formed by the second retransmission start element and the second retransmission end element is smaller than the interval formed by the second discard start element and the second discard end element.

[0034] The second matrix column may further include a matrix column quantity element. The matrix column quantity element is generated by a random function or is input by a user. The value in the matrix column quantity element is equal to the number of columns of the first matrix, that is, the value in the matrix column quantity element indicates how many image slices need to be discarded in the first image frame.

[0035] The second discard start element, the second discard end element, the second retransmission start element, and the second retransmission end element are all smaller than the first fragment quantity element.

[0036] There is no intersection between the interval formed by the first discard start element and the first discard end element and the interval formed by the second discard start element and the second discard end element. For example, the second discard start element is greater than the first discard end element.

[0037] The elements in the first matrix may all be generated by a random function, or may be input by a user, which is not specifically limited here.

[0038] The following will Figure 2 Taking the example shown in the figure as an example, the first matrix is ​​introduced in detail. Figure 2As shown, the values ​​of the first slice number element and the matrix column number element in the fifth row of the first matrix are 15 and 5 respectively. Therefore, the first image frame has a total of 15 image slices, and 5 of the image slices need to be discarded. The discard start sequence number in the first matrix column is 1, and the discard end sequence number is 2; the discard start sequence number in the second matrix column is 4, and the discard end sequence number is 7; the discard start sequence number in the third matrix column is 8, and the discard end sequence number is 8; the discard start sequence number in the fourth matrix column is 10, and the discard end sequence number is 11; the discard start sequence number in the fifth matrix column is 13, and the discard end sequence number is 14. The retransmission start sequence number in the first matrix column is 1, and the retransmission end sequence number is 2; the retransmission start sequence number in the second matrix column is 5, and the retransmission end sequence number is 6; the retransmission start sequence number in the third matrix column is 8, and the retransmission end sequence number is 8; the retransmission start sequence number in the fourth matrix column is 10, and the retransmission end sequence number is 11; the retransmission start sequence number in the fifth matrix column is 13, and the retransmission end sequence number is 14.

[0039] It can be understood that the above-mentioned first matrix is ​​only a specific example. In actual applications, the number of columns of the first matrix can be less or more, and the value of each element in the first matrix can also be other numerical values. Various different matrices can be obtained by changing the number of columns of the first matrix and the values ​​of the elements in the first matrix.

[0040] S102: The computing device generates a first data stream and a first retransmission data stream of a first image frame according to a first matrix.

[0043] It can be understood that the above-mentioned first data stream and first retransmission data stream are only used as specific examples. In actual applications, different matrices can generate different first data streams and first retransmission data streams accordingly, thereby constructing a variety of verification messages to verify the smart network card.

[0048] The first discard start element is used to indicate the first discard start sequence number of the image slices to be discarded in the first image frame. Therefore, according to the first discard start sequence number and the first discard end element, it is possible to determine which image slices in the first image frame are to be discarded.

[0049] The first retransmission start element is used to indicate the first retransmission start sequence number of the image slice that needs to be retransmitted in the first image frame. The first retransmission end element is used to indicate the first retransmission end sequence number of the image slice that needs to be retransmitted in the first image frame. Therefore, according to the first retransmission start sequence number and the first retransmission end element, it is possible to determine which image slices in the first image frame are to be retransmitted. Since only the discarded image slices need to be retransmitted, the interval formed by the first retransmission start element and the first retransmission end element belongs to the interval formed by the first discard start element and the first discard end element. Here, belonging means that the interval formed by the first retransmission start element and the first retransmission end element is equal to the interval formed by the first discard start element and the first discard end element, or the interval formed by the first retransmission start element and the first retransmission end element is smaller than the interval formed by the first discard start element and the first discard end element.

[0050] The first number of slices element is used to indicate the number of image slices in the first image frame.

[0053] The second retransmission start element is used to indicate the second retransmission start sequence number of the image slice that needs to be retransmitted in the second image frame. The second retransmission end element is used to indicate the second retransmission end sequence number of the image slice that needs to be retransmitted in the second image frame. Therefore, according to the second retransmission start sequence number and the second retransmission end element, it is possible to determine which image slices in the second image frame are to be retransmitted. Since only the discarded image slices need to be retransmitted, the interval formed by the second retransmission start element and the second retransmission end element belongs to the interval formed by the second discard start element and the second discard end element. Here, belonging means that the interval formed by the second retransmission start element and the second retransmission end element is equal to the interval formed by the second discard start element and the second discard end element, or the interval formed by the second retransmission start element and the second retransmission end element is smaller than the interval formed by the second discard start element and the second discard end element.

[0056] The following will Figure 4 Taking the example shown in the figure as an example, the first matrix is ​​introduced in detail. Figure 4 As shown, the 5 slice number elements in the fifth row of the first matrix are 6, 8, 6, 6, and 4. That is, the first image frame has 6 image slices, the second image frame has 8 image slices, the third image frame has 6 image slices, the fourth image frame has 6 image slices, and the fifth image frame has 4 image slices.

In other words, the first image frame needs to discard the image slices with sequence numbers 1 to 3, and retain the image slices with sequence numbers 0, 4 to 5; the second image frame needs to discard the image slices with sequence numbers 2 to 4, and retain the image slices with sequence numbers 0, 5 to 7; the third image frame needs to discard the image slices with sequence numbers 4 to 5, and retain the image slices with sequence numbers 0 to 3; the fourth image frame needs to discard the image slices with sequence numbers 0 to 5; the fifth image frame needs to discard the image slice with sequence number 3, and retain the image slices with sequence numbers 0 to 2.
