Problems solved by technology

[0004] The existing technology does not help the WeChat program of the mobile phone. Through the sensors on the three fixed points of the knee joint, the range of motion of the knee joint cannot be accurately measured, and it is not convenient for medical staff to pay attention to the range of motion of the patient's knee joint at any time, so as to ensure the patient's operation. after recovery

Embodiment 1

[0086] In the present invention, the WeChat applet running steps include:

[0087] The essence of a WeChat applet is an app between a web app and a native app. It has a rich interface for calling various functions of the mobile phone, and at the same time has flexibility and cross-platform functions.

[0088] WeChat applets run on three terminals: iOS, Android, and developer tools for debugging.

[0089] iOS: The javascript code of the applet runs in JavaScriptCore and is rendered by WKWebView. The environments include iOS8, iOS9, and iOS10.

[0090] Android: The javascript code of the applet is parsed by X5 JSCore and rendered by X5 based on the MobileChrome 53 / 57 core.

[0091] On the development tool: the javascript code of the applet runs in nwjs and is rendered by Chrome Webview (from the official documentation).

[0092] The WeChat applet operating framework involved in the present invention includes two parts View layer (one or more), App Service logic layer (one), th...

Embodiment 2

[0116] How WeChat Mini Programs perform rendering and event processing, including:

[0117] rendering:

[0118] There are three main ways of page rendering:

[0119] Pure web rendering;

[0120] Pure NATIVE rendering;

[0121] Hybrid rendering, that is, the combination of web rendering and NATIVE rendering.

[0122] The rendering process of the page is as follows:

[0123] (1) Enter the official website to register the appId and download the WeChat developer tools;

[0124] (2) After entering the developer tool, click the app.json file, and create a new page under the pages field;

[0125] (3) Create a folder under the Wechat Development Code directory to store static resources (icons, pictures, etc.) The newly created page will have four files:

[0126] .wxml file: render the page structure with tag language;

[0127] .wxss file: set the style of page components;

[0128] .js file: logic to manage pages and data;

[0129] .json file: set the title bar of the page, etc....

[0143] javascript running engine:

[0144] A "JavaScript runtime" is often referred to as a virtual machine.

[0145] The JavaScript virtual machine is a process virtual machine, specially designed to interpret and execute JavaScript code.

[0146] The basic job of the JavaScript engine is to convert the JavaScript code written by developers into efficient and optimized code, so that it can be interpreted by the browser or even embedded in the application. Every JavaScript engine implements a version of ECMAScript, of which JavaScript is a fork. As ECMAScript continues to evolve, so do JavaScript engines. The reason there are so many different engines is because each of them is designed to run in a different web browser, headless browser, or runtime environment like Node.js, and its sole purpose is to read and Compile JavaScript code.

[0147] The parsing engine is to dynamically execute JavaScript strings according to the language standard defined by ECMAScript;

Abstract

The invention belongs to the technical field of WeChat applets, and discloses an image-based knee joint motion range measurement method, a terminal, a medium and a mobile phone. The method comprises the steps of: enabling a WeChat client to call various native interfaces through the WeChat applets; and performing rendering and event processing on a single page through an analysis engine according to the obtained motion track data of the marks attached to the joint of the patella and the middle of the knee joint attached to the middle line of the diseased limb and attached to the joint of the patella and the middle line of the leg, translating the processed data into native data, and presenting the native data on a native interface. In view of wide application of the intelligent mobile phone at present, a WeChat applet is developed by means of the WeChat program of the mobile phone of the patient, the motion range of the knee joint can be accurately measured through the inductors on the three fixed point positions of the knee joint, medical care can pay attention to the motion range of the knee joint of the patient at any time through the applet, and postoperative rehabilitation of the patient is guaranteed. The method can be conveniently obtained and spread in WeChat, and has excellent use experience.

Description

technical field [0001] The invention belongs to the technical field of WeChat applets, and in particular relates to a method, a terminal, a medium, and a mobile phone for measuring the range of motion of a knee joint based on an image. Background technique [0002] At present, after total knee arthroplasty, patients are required to perform knee joint movement every day. The knee joint movement angle is the gold standard for evaluating and measuring total knee arthroplasty. Joint activities until the patient is discharged from the hospital 4 days after the operation. The patient needs to reach a knee joint movement angle of 110°. After returning home, the patient needs to perform functional exercises at home until 6-8 weeks after the operation, but the patient can perform functional exercises at home It is impossible to confirm whether the degree of motion of the knee joint reaches the standard every day, and the existing technology does not provide a way of thinking. [000...
