第一种方法

通过settings.json配置“subwindows”字段去显示

settings.json

{
    "SettingsVersion": 1.2,
    "SeeDocsAt": "https://github.com/Microsoft/AirSim/blob/master/docs/settings.md",
    "SimMode": "Multirotor",
    "ViewMode": "FlyWithMe",
    "SubWindows": [
        {
            "WindowID": 0,
            "CameraName": "front_center_custom",
            "ImageType": 0,
            "Visible": true,
            "ImageSize": [480, 270],
            "CameraPosition": [0.0, 0.0, -2.5],
            "CameraRotation": [0.0, 0.0, 0.0]
        },
        {
            "WindowID": 1,
            "CameraName": "front_center_custom",
            "ImageType": 3,
            "Visible": true,
            "ImageSize": [480, 270],
            "CameraPosition": [0.0, 0.0, -2.5],
            "CameraRotation": [0.0, 0.0, 0.0]
        },
        {
            "WindowID": 2,
                "CameraName": "front_center_custom",
                "ImageType": 5,
                "Visible": true,
                "ImageSize": [480, 270],
                "CameraPosition": [0.0, 0.0, -2.5],
                "CameraRotation": [0.0, 0.0, 0.0]
        }
    ],
    "Vehicles": {
        "Drone": {
            "VehicleType": "SimpleFlight",
            "DisplayName": "My First Drone",
            "AutoCreate": true
        }
    }
}

第二种方法

利用pygame绘制窗口并获取无人机FPV实时图像呈现

键盘控制及摄像机实时显示.py

import numpy as np

# >------>>>  pygame settings   <<<------< #
pygame.init()

screen = pygame.display.set_mode((800, 144))
pygame.display.set_caption("screen")
screen.fill((0, 0, 0))

# >------>>>  AirSim settings   <<<------< #
# 这里改为你要控制的无人机名称(settings文件里面设置的)

    "segmentation": airsim.ImageType.Segmentation,
    "disparity": airsim.ImageType.DisparityNormalized,
    "Infrared": airsim.ImageType.Infrared
}

# 基础的控制速度(m/s)
