Abstract
The present invention is a kind of Urine test paper image-recognizing method that ability is corrected with color.After the test paper urine examination, urine test paper and standard color card are generated into correction model together, pass through mobile phone photograph, automatic data collection test paper image, is uploaded to cloud platform, and Harris Corner Detection uncalibrated images are carried out afterwards, cloud platform carries out the reduction of color, and recognition result is returned into mobile phone after treatment.The recognition methods obtains test paper image first；Then according to the color correction colour atla color data in image and standard color card data generation color correction model, it is uploaded to cloud platform, Harris Corner Detection uncalibrated images are carried out afterwards, brightness adjustment and color correction are carried out to test paper image, carry out accurate color rendition, finally, result is identified, mobile phone is returned to.This method efficiency high is simple to operate, and cost is low, it is to avoid the problem of ambient light interference and low eye recognition accuracy rate, while available for screening early stage Patients with Chronic Renal Disease, reducing disease risks.
Description
Technical field
The invention belongs to image recognition category, more particularly to a kind of Urine test paper image recognition that ability is corrected with color
Method, is detected for hospital to Urine in Patients, or patient self carries out urine detection.
Background technology
Usually require to carry out the diagnosis of disease, profit with reference to a variety of medical parameters in the diagnosis in medical domain, many diseases
It is than one of wide and maneuverable detection method that medical parameter is obtained with test paper detection.And in numerous detections, urine
Liquid analysis is the important analysis and assessment means of many disease detections, and the medical parameter of urine is significant in clinical diagnosis.Mesh
Before, many electronic equipments have been enter into medical domain, and Urine Analyzer also occurs in succession.Urine Analyzer typically has special examination
Agent band, reagent strip row includes several reagent blocks, is equally distributed on test paper.Scribbled on indicator paper block and be specifically used to detect respective items
Purpose chemical reagent, the number of reagent block determines the number of detection project.The chemistry of measurement respective item is scribbled on reagent block
Material, can occur color reaction with urine contact.According to the color change degree of reagent block, it can be determined that go out homologue in urine
The concentration of matter simultaneously obtains testing result.
Urinalysis quilt in terms of diagnosis of urinary diseases, observation of curative effect and prognosis, the diagnosis of metabolic system disease
Extensive use.Uroscopy is carried out using conventional method, process is complicated and the cycle is longer.Although Urine Analyzer can be quickly accurate
The indices of true measurement urine, but most of Urine Analyzers are prohibitively expensive and detection range is limited, it is necessary to using supporting
Test paper detected.And traditional human eye contrast knowledge method for distinguishing efficiency is low, and easily by staff's subjective factor
Influence, in order to solve these problems, it is proposed that it is a kind of with color correct ability Urine test paper image-recognizing method, move
Routine urinalysis detection can be carried out in dynamic equipment, helps user to be in and carries out urine self-inspection, employ the side of Dry Chemical Analysis on Urine
Method, it is that can obtain test paper color of image value to scan test paper and correction colour atla using mobile device camera, analytic index concentration, tool
Have with low cost, the advantages of detecting quick, easy to use.
The content of the invention
The invention reside in provide a kind of Urine test paper image-recognizing method that ability is corrected with color, with low cost, letter
It is single directly perceived, detection time is shortened, with higher accuracy rate.
The invention reside in provide a kind of Urine test paper image-recognizing method that ability is corrected with color, including following step
Suddenly：
Step 1, acquisition urine test paper image；
Step 2, Urine test paper and standard color card data are generated into color correction model, be uploaded to cloud platform；
Step 3, cloud platform Harris Corner Detection uncalibrated images, cloud platform carry out color rendition；
Recognition result is beamed back mobile phone by step 4, cloud platform.
Brief description of the drawings
Fig. 1 is the structural representation of the urine test paper.
Fig. 2 is the color correction model of Urine test paper and the generation of standard color card data.
Fig. 3 is Urine test paper color correction capability operation flow chart.
Embodiment
The Urine test paper image-recognizing method for correcting pattern based on color given by the present invention is carried out below in conjunction with the accompanying drawings
Describe in detail.
Step 1：It is described in detail with reference to Fig. 1, Fig. 1 is the urine test paper structural representation, including two parts：It is coated with
The detection zone numeral 2,3,4 of particular detection reagent, digital 1 region of handle portion of Test paper, patient obtains I
The sample of urine, the right hand holds the part of the handle of detection, and the detection zone for being coated with particular detection reagent is instilled into urine, treated
After reaction completely, Urine test paper sample to be detected is obtained.
Step 2：It is described in detail with reference to Fig. 2, Fig. 2 is correction model, two parts composition is had, above and below the model is divided into
Two parts, last point is Urine test paper sample graph 1 to be detected, and next part is standard color card, and standard color card has 5 color marks
Quasi- region unit（Zone digit 6,7,8,9,10）.
Step 3：The model is shot with mobile phone, the image of shooting is uploaded to cloud platform, Harris angles are carried out by cloud platform
Point detection, the Harris Corner Detections uncalibrated image is used to eliminate shadow of the shake in shooting process to image taking results
Ring, after Harris processing images, establishing criteria colour atla treats Test paper, carries out accurate color rendition.
Step 4：By the image after color rendition, stored with jpg forms, cell-phone customer terminal is beamed back again, for patient
Check result.
Claims (2)
1. a kind of Urine test paper image-recognizing method that ability is corrected with color, it is characterised in that comprise the following steps：Step
