Embodiment 1
[0038] Quantitative analysis is carried out with nitrite test strips, using the first method, the specific process is as follows:
[0039] Step 1: The user places a nitrite test paper standard card and two new unknown samples in the same field of view, and takes pictures, see references figure 1 .1.
[0040] in reference figure 1 .1 is the original picture taken, different cameras have different resolutions, and the pictures taken are of different sizes. figure 1 .1 The resolution is 1936*2592, and the size is 1.17M. For the convenience of calculation, the figure 1 .1 Compressed into a size of no more than 40K (see references figure 1 .2);
[0041] The second step: in the reference material figure 1 .2 Carry out threshold segmentation edge recognition, extract the standard sample area and unknown sample area in the picture, as in the reference figure 1 .3 shown.
[0042] After extracting the weighted gray value of each pixel in the pixel area corresponding to the standa...
Embodiment 2
[0048] The semi-quantitative analysis is carried out by the determination of pesticide residues, and the first method is adopted. The specific process is as follows:
[0049] Step 1: Place three pesticide residue standard cards and a new unknown sample in the same field of view, see references for photos figure 2 .1.
[0050] in reference figure 2 .1 is the original picture of the pesticide residues captured in the reference materials figure 2 .1 The resolution is 2322*4128, for the convenience of calculation, the figure 2 .1 compressed into a resolution of 360*270 (see the reference figure 2 .2).
[0051] The second step: in the reference material figure 2 .2 Perform threshold segmentation to extract the standard sample area and unknown sample area in the picture, as in the reference figure 2 .3 shown.
[0052] The fourth step is to calculate the H, I, S values of the standard sample area. According to the value of the largest difference between H, I, and S i...
Embodiment 3
[0057] Determination of salbutamol with colloidal gold reagent card adopts the first method, and the specific process is as follows:
[0058] Step 1: Take pictures of the albuterol standard card and sample card, as in the reference materials image 3 .1 shown.
[0059] Since the color block of colloidal gold is small, it is easy to cause pixel distortion after compression, so it is necessary to directly intercept the color block information according to the position of the CT line.
[0060] The second step: in the reference material image 3 .1 Carry out threshold segmentation, extract the standard sample area and unknown sample area in the picture according to the position of the CT line, as in the reference material image 3 .2 shown.
[0061] Step 3: Obtain the optimal standard curve.
[0062] The weighted gray value of the standard sample obtained in the above step, H value, I value, the ratio of the respective T line and C line in the S value, according to the semi-lo...
