求助：Appium中matchImagesFeatures方法无法正常使用问题排查

我在Appium框架中使用matchImagesFeatures方法时遇到问题，该方法始终返回无匹配结果，也无法生成预期的可视化对比图。其他图像对比方法（如findImageOccurrence和getImagesSimilarity）均可正常工作，但我需要matchImagesFeatures的灵活性来处理图像缩放与旋转场景。

环境配置 #

• Appium客户端版本：9.3.0
• Appium服务端版本：2.12.1
• images插件版本：images@3.0.21
• JDK版本：jdk-21.0.5.11-openj9

代码实现 #

public boolean isImagePresent(String baseImagePath, String secondImagePath) {
    try {
         // Load the base image as a byte array
        byte[] baseImage = Files.readAllBytes(Paths.get(baseImagePath));
        byte[] secondImage = Files.readAllBytes(Paths.get(secondImagePath));

        // Generate diff image path automatically based on baseline image path
        String diffImagePath = baseImagePath.replace(".png", "_present_diff.png");

        // Perform feature-based image comparison
        FeaturesMatchingResult result = driver.matchImagesFeatures(
            baseImage , 
            secondImage,
            new FeaturesMatchingOptions()
            .withDetectorName(FeatureDetector.ORB)    // Use ORB detector
            .withGoodMatchesFactor(40)             // Adjust match threshold
            .withMatchFunc(MatchingFunction.BRUTE_FORCE_HAMMING)  // Matching function
            .withEnabledVisualization()                // Enable visualization
        );

        System.out.println("result : " + result);
        
        // Assertions
        if (result.getCount() > 0) {
            Files.write(Paths.get(diffImagePath), result.getVisualization());
            System.out.println("Visualization saved at: " + diffImagePath);
            System.out.println("Match found! Good matches: " + result.getCount());
            return true;
        } else {
            System.out.println("No match found.");
            return false;
        }
        
    }catch (Exception e) {
        e.printStackTrace();
        return false; // Return false if an exception occurs
    }
}

控制台输出 #

result : io.appium.java_client.imagecomparison.FeaturesMatchingResult@87dfcecc
No match found.

预期结果 #

期望生成带有特征匹配连线的可视化对比图，清晰展示两张图像中匹配的特征点关联关系。
