ios免越狱自动化测试脚本开发(10)-屏幕截图与OCR文字识别

OCR测试

在IDEA中运行如下代码:

    logd("开始执行脚本...")

    if (appLaunch("com.ss.iphone.ugc.Aweme")) {
        sleep(5000);
        logd('已启动应用')
    } else {
        logw('应用启动失败')
    }

    //ocr初始化,参数要根据自己的电脑系统和环境进行修改
    let ocrLite = {
        "type": "ocrLite",
        "baseDir": "/Users/feiyun/Downloads/IOS/v2.1.0/center/ios-center-2.1.0/OcrLiteNcnn",
        "cpuType": "Darwin-Lib-CPU"
    }

    let inited = ocr.initOcr(ocrLite)
    logd("初始化结果 -> " + inited);
    if (!inited) {
        loge("error : " + ocr.getErrorMsg());
        return;
    }

    var cap = image.captureFullScreen();   //屏幕截图
    if (cap) {
        var data = file.getSandBoxDir();   //获取当前设备沙盒的文件夹路径
        let path = data + "/Temp/Image/"   //临时图片存储路径
        if (!file.exists(path)) {
            file.mkdirs(path);   //创建临时文件目录
        }

        if (image.saveTo(cap, path + "screen.png")) {
            image.recycle(cap);  //图片回收

            //读取一个bitmap
            let bitmap = image.readBitmap(path + "screen.png");
            if (!bitmap) {
                loge("读取图片失败");
            }

            console.time("1")
            logd("start---ocr");
            // 对图片进行识别
            let result = ocr.ocrBitmap(bitmap, 20 * 1000, {});
            //图片要回收
            image.recycle(bitmap)
            //释放所有资源
            ocr.releaseAll();

            logd(result)
            if (result) {
                logd("ocr结果-》 " + JSON.stringify(result));
                for (var i = 0; i < result.length; i++) {
                    var value = result[i];
                    logd("文字 : " + value.label + " x: " + value.x + " y: " + value.y + " width: " + value.width + " height: " + value.height);
                }
            } else {
                logw("未识别到结果");
            }

            logd("耗时: " + console.timeEnd(1) + " ms")
        } else {
            loge("文件保存失败");
        }
    } else {
        loge("截图失败");
    }

代码优化

在前文中,我们详细讲解了ocr初始化参数的获取方法。
其中,参数baseDir是ocr库的目录路径。这里我们可以自动获取。
这样,在不同的系统环境中,就不需要判断和配置了。

来运行一段测试demo:

let baseDir = file.getSandBoxDir();   //获取当前设备沙盒的文件夹路径
    var arrurl = baseDir.split('/');
    if(arrurl[arrurl.length-2] == 'scriptbin') {
        baseDir = baseDir.replace(arrurl[arrurl.length-2] + "/" + arrurl[arrurl.length-1],"") + "OcrLiteNcnn"
        logd(baseDir);
    }

运行后,即可得到OcrLiteNcnn库文件的目录:
/Users/feiyun/Downloads/IOS/v2.1.0/center/ios-center-2.1.0/OcrLiteNcnn

温馨提示:此处内容需要后才能查看!

参数cpuType,可以根据baseDir的值,进行粗略判断。
具体的判断方法,大家可以自行思考并测试。由于我有点懒,
这里就不提供具体的代码了。
