Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, an embodiment of the present invention provides a kind of testing results of Urine test paper to determine method, which can be with
Include the following steps：
S101 determines that the target color values of Urine test paper image detection region, target color values are each picture in detection zone
The average value of plain color value.
Urine test paper image is made of pixel, and each pixel has corresponding color value, it is thus determined that detection zone
The average value of each pixel color value, i.e. target color values in domain.The purpose for determining target color values is in order to by target color values
It is compared with the color value of reference colour, so that it is determined that the testing result of Urine test paper.

Difference is：In RGB color, the value of chromatism between target color values and preset standard color color value.
Urine test paper can quantify the concentration of a certain ingredient in detection urine, and with concentration difference, Urine test paper shows
Color it is also different, this just needs to be compared with the color of detected Urine test paper using standard color, so that it is determined that the inspection
The concentration of ingredient in test paper.Standard color is typically preset, and different standard colors corresponds to different constituent concentrations.
Existing testing result determines method, is usually compared Test paper from different standard colors by naked eyes
It is right, searching and the immediate standard color of Test paper color, therefore there is a problem of that error is big.It, can in the embodiment of the present invention
