Embodiment 1

[0074] Such as figure 1 Shown is a flow chart of a test paper positioning method of the present invention, the method may include the following steps:

[0075] Step S101: Obtain the initial position information of the positioning frame of each type of test paper pad in the test paper picture set by the operator.

[0076] Wherein, the initial position information of the positioning frame may include: the length and width of the positioning frame of each type of test paper pad, and the initial coordinate value of the first vertex. Preferably, the first vertex may be the vertex of the lower left corner of the positioning frame.

[0077] In the embodiment of the present invention, since the test strip is only a part of the input picture, it needs to be separated from the input picture, and then each type of test paper pad can be separated from the test strip. For this process, the initial positioning of the test strip of the input image can be obtained by relying on the observat...

Embodiment 2

[0106] Such as Figure 4 Shown is a flow chart of another test paper positioning method of the present invention, which method may include:

[0107] Step S401: Obtain the initial position information of the positioning frame of each type of test paper pad in the test paper picture set by the operator.

[0108] Wherein, the acquired initial position information of the positioning frame includes: the length and width of the positioning frame of each type of test paper pad, and the initial coordinate value of the first vertex.

[0109] In the embodiment of the present invention, the operator can directly use the mouse to mark the initial position of the positioning frame of each type of test paper pad in the input test paper picture. Of course, before step S401 is performed, the operator can also initially position the test paper pad, that is, use the mouse to initially calibrate the coordinate values ​​of the four vertices of the test paper picture in the input test paper pictu...

Embodiment 3

[0150] Such as Figure 7 As shown, it is a structural schematic diagram of a test paper positioning system of the present invention, and the system may include:

[0151] The first obtaining module S701 is used to obtain the initial position information of the positioning frame of each type of test paper pad in the test paper picture set by the operator.

[0152] Wherein, the acquired initial position information of the positioning frame includes: the length and width of the positioning frame of each type of test paper pad, and the initial coordinate value of the first vertex.

[0153] As another embodiment of the present invention, the operator can first set the coordinates of the four vertices of the test strip picture in the input test strip picture, and then calibrate the initial positions of various test paper pads on the test strip picture. Therefore, The first obtaining module is also used to obtain the coordinate values ​​of the four vertices of the test strip picture ...

Abstract

The invention discloses a test paper location method and a test paper location system. When a system receives an initial position of a location frame of each type of test paper pad in a test paper picture set by an operator, to the location of each type of the teat paper pad, the system obtains first pixel information of a picture in the location frame of the test paper pad so as to compute the main color energy of the picture in the location frame of the test paper pad, and then the system adjusts a position of the location frame of the test paper pad in a preset adjustment range and determines the corresponding position of the location frame when the main color energy is maximized to be the final position of the location frame of the test paper pad; therefore, the precise and quick location on each test paper pad of a test paper picture is realized, and the precision and high efficiency of the examination of the test paper are ensured.

Description

technical field [0001] The invention relates to the technical field of test paper inspection, and more specifically relates to a test paper positioning method and system. Background technique [0002] According to the survey, when conducting virus testing, water quality testing, solution pH testing, blood testing, and urine testing, etc., the test results of the samples are obtained through test strips, especially in hospitals, which are carried out every day. A large number of test papers are inspected. At this time, if the concentration identification of the test papers is carried out by manual identification, the workload will be very large. Therefore, in order to improve the inspection efficiency, the test papers are usually made into test paper pads and arranged on the test paper strips. The equipment realizes the detection of multiple types of test paper at one time. Among them, in the detection process, it is necessary to quickly and accurately position each test pap...
