【Elasticsearch】-图片向量化存储

需要结合深度学习模型

1、pom依赖

注意结尾的webp-imageio 包，用于解决ImageIO.read读取部分图片返回为null的问题

<dependency><groupId>org.openpnp</groupId><artifactId>opencv</artifactId><version>4.7.0-0</version></dependency><dependency><groupId>com.microsoft.onnxruntime</groupId><artifactId>onnxruntime</artifactId><version>1.17.1</version></dependency><!-- 服务器端推理引擎 --><dependency><groupId>ai.djl</groupId><artifactId>api</artifactId><version>${djl.version}</version></dependency><dependency><groupId>ai.djl</groupId><artifactId>basicdataset</artifactId><version>${djl.version}</version></dependency><dependency><groupId>ai.djl</groupId><artifactId>model-zoo</artifactId><version>${djl.version}</version></dependency><!-- Pytorch --><dependency><groupId>ai.djl.pytorch</groupId><artifactId>pytorch-engine</artifactId><version>${djl.version}</version></dependency><dependency><groupId>ai.djl.pytorch</groupId><artifactId>pytorch-model-zoo</artifactId><version>${djl.version}</version></dependency><!-- ONNX --><dependency><groupId>ai.djl.onnxruntime</groupId><artifactId>onnxruntime-engine</artifactId><version>${djl.version}</version></dependency><!-- 解决ImageIO.read 读取为null --><dependency><groupId>org.sejda.imageio</groupId><artifactId>webp-imageio</artifactId><version>0.1.6</version></dependency>

2、加载模型

注意提前设置环境变量，pytorch依赖环境dll文件，如果不存在，则默认下载

System.setProperty("ENGINE_CACHE_DIR", modelPath);

import ai.djl.Device;
import ai.djl.modality.cv.Image;
import ai.djl.repository.zoo.Criteria;
import ai.djl.training.util.ProgressBar;
import ai.djl.translate.Translator;public Criteria<Image, T> criteria() {Translator<Image, T> translator = getTranslator(arguments);try {JarFileUtils.copyFileFromJar("/onnx/models/" + modelName, PathConstants.ONNX, null, false, true);} catch (IOException e) {throw new RuntimeException(e);}
//        String model_path = PathConstants.TEMP_DIR + PathConstants.ONNX + "/" + modelName;String modelPath = PathConstants.TEMP_DIR + File.separator+PathConstants.ONNX_NAME+ File.separator + modelName;log.info("路径修改前:{}",modelPath);modelPath= DjlHandlerUtil.getFixedModelPath(modelPath);log.info("路径修改后:{}",modelPath);Criteria<Image, T> criteria =Criteria.builder().setTypes(Image.class, getClassOfT()).optModelUrls(modelPath).optTranslator(translator).optDevice(Device.cpu()).optEngine(getEngine()) // Use PyTorch engine.optProgress(new ProgressBar()).build();return criteria;}protected Translator<Image, float[]> getTranslator(Map<String, Object> arguments) {BaseImageTranslator.BaseBuilder<?> builder=new BaseImageTranslator.BaseBuilder<BaseImageTranslator.BaseBuilder>() {@Overrideprotected BaseImageTranslator.BaseBuilder self() {return this;}};return new BaseImageTranslator<float[]>(builder) {@Overridepublic float[] processOutput(TranslatorContext translatorContext, NDList ndList) throws Exception {return ndList.get(0).toFloatArray();}};}

3、FaceFeatureTranslator

import ai.djl.modality.cv.Image;
import ai.djl.modality.cv.transform.Normalize;
import ai.djl.modality.cv.transform.ToTensor;
import ai.djl.ndarray.NDArray;
import ai.djl.ndarray.NDList;
import ai.djl.translate.Batchifier;
import ai.djl.translate.Pipeline;
import ai.djl.translate.Translator;
import ai.djl.translate.TranslatorContext;/*** @author gc.x* @date 2022-04*/
public final class FaceFeatureTranslator implements Translator<Image, float[]> {public FaceFeatureTranslator() {}@Overridepublic NDList processInput(TranslatorContext ctx, Image input) {NDArray array = input.toNDArray(ctx.getNDManager(), Image.Flag.COLOR);Pipeline pipeline = new Pipeline();pipeline// .add(new Resize(160)).add(new ToTensor()).add(new Normalize(new float[]{127.5f / 255.0f, 127.5f / 255.0f, 127.5f / 255.0f},new float[]{128.0f / 255.0f, 128.0f / 255.0f, 128.0f / 255.0f}));return pipeline.transform(new NDList(array));}@Overridepublic float[] processOutput(TranslatorContext ctx, NDList list) {NDList result = new NDList();long numOutputs = list.singletonOrThrow().getShape().get(0);for (int i = 0; i < numOutputs; i++) {result.add(list.singletonOrThrow().get(i));}float[][] embeddings = result.stream().map(NDArray::toFloatArray).toArray(float[][]::new);float[] feature = new float[embeddings.length];for (int i = 0; i < embeddings.length; i++) {feature[i] = embeddings[i][0];}return feature;}@Overridepublic Batchifier getBatchifier() {return Batchifier.STACK;}
}

4、BaseImageTranslator

5、添加到ES

float[] feature;
// 构建文档Map<String, Object> dataMap = req.getDataMap();// 内置参数dataMap.put("_es_doc_type", "IMAGE");dataMap.put("vector", feature);IndexRequest<Map> request = IndexRequest.of(i -> i.index(req.getIndexLib()).id(req.getDocId()).document(dataMap));IndexResponse response = esClient.index(request);boolean flag = response.result() == Result.Created;log.info("添加文档id={},结果={}", req.getDocId(), flag);
