ImageAI续-DeepStack(一) 使用Python快速简单实现人脸检测、人脸匹配、人脸比较

上一篇人脸识别 使用了VISION-FACE功能 这一次物体检测需要VISION-DETECTION

#linux
docker run -e VISION-DETECTION=True -e MODE=High -v localstorage:/datastore -p 8080:5000 deepquestai/deepstack

#windows
deepstack --VISION-DETECTION True --PORT 8080

import requests

import matplotlib.pyplot as plt
import cv2

def useUrl():
    host = "http://192.168.0.101:8080"
    # 加载待测图片
    image_data = open("1.jpg","rb").read()
    img = cv2.imread("1.jpg")
    
    # 调用 http://192.168.0.101:8080/v1/vision/detection 检测图片内物体
    response = requests.post(host+"/v1/vision/detection",files={"image":image_data}).json()
    # 将检测结果在图片内框出标注
    font = cv2.FONT_HERSHEY_SIMPLEX
    for obj in response["predictions"]:
        print(obj)
        conf = obj["confidence"]*100
        label = obj["label"]
        y_max = int(obj["y_max"])
        y_min = int(obj["y_min"])

        pt1 = (x_min,y_min)
        pt2 = (x_max,y_max)
        cv2.rectangle(img,pt1,pt2,(255,0,0),2)
        cv2.putText(img,'{} {:.2f}'.format(label,conf),(x_min,y_min-15),font,1,(255,0,0),4)
    plt.imshow(img)
    plt.axis('off')
    plt.show()

def pythonsdk():
    config = ServerConfig("http://192.168.0.101:8080")
    detection = Detection(config)
    
    ##检测图片中物体
    response=detection.detectObject("2.jpg",output="2_output.jpg")
    for obj in response:

Name: person, Confidence: 0.5288314, x_min: 195, y_min: 220, x_max: 464, y_max: 816
Name: horse, Confidence: 0.5871692, x_min: 135, y_min: 220, x_max: 475, y_max: 821
Name: dog, Confidence: 0.9199933, x_min: 105, y_min: 496, x_max: 350, y_max: 819
