AirSim在UE4中運(yùn)行時(shí)顯示第一人稱捕獲圖像窗口——settings.json配置和pygame兩種方法

一、通過settings.json配置“subwindows”字段去顯示
{
? ? "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
}
? ? }
}
自己修改時(shí)注意窗口索引的正確性。
二、利用pygame繪制窗口并獲取無(wú)人機(jī)FPV實(shí)時(shí)圖像呈現(xiàn)
import sys
import time
import airsim
import pygame
import CV2
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 ? <<<------< #
# 這里改為你要控制的無(wú)人機(jī)名稱(settings文件里面設(shè)置的)
vehicle_name = "Drone"
AirSim_client = airsim.MultirotorClient()
AirSim_client.confirmConnection()
AirSim_client.enableApiControl(True, vehicle_name=vehicle_name)
AirSim_client.armDisarm(True, vehicle_name=vehicle_name)
AirSim_client.takeoffAsync(vehicle_name=vehicle_name).join()
image_types = {
? ?"scene": airsim.ImageType.Scene,
? ?"depth": airsim.ImageType.DepthVis,
? ?"seg": airsim.ImageType.Segmentation,
? ?"normals": airsim.ImageType.SurfaceNormals,
? ?"segmentation": airsim.ImageType.Segmentation,
? ?"disparity": airsim.ImageType.DisparityNormalized,
? ?"Infrared": airsim.ImageType.Infrared
}
# 基礎(chǔ)的控制速度(m/s)
vehicle_velocity = 2.0
# 設(shè)置臨時(shí)加速比例
speedup_ratio = 10.0
# 用來(lái)設(shè)置臨時(shí)加速
speedup_flag = False
# 基礎(chǔ)的偏航速率
vehicle_yaw_rate = 5.0
while True:

? ?# 設(shè)置速度控制以及設(shè)置偏航控制
? ?AirSim_client.moveByVelocityBodyFrameAsync(vx=velocity_x, vy=velocity_y, vz=velocity_z, duration=1,
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? yaw_mode=airsim.YawMode(True, yaw_or_rate=yaw_rate), vehicle_name=vehicle_name)
? ?temp_image1 = AirSim_client.simGetImage('0', image_types["scene"], vehicle_name=vehicle_name)
? ?image1 = CV2.imdecode(airsim.string_to_uint8_array(temp_image1), CV2.IMREAD_COLOR)
? ?CV2.imwrite('screen/visual1.png', image1)
? ?# 利用pygame庫(kù)加載保存的第一視角圖像,
? ?screen_image1 = pygame.image.load("screen/visual1.png")
? ?# 圖像坐標(biāo)系,左上角為(0, 0),在此放置圖片
? ?screen.blit(screen_image1, (0, 0))
? ?pygame.display.flip()
? ?pygame.display.update()
? ?temp_image2 = AirSim_client.simGetImage('0', image_types["Infrared"], vehicle_name=vehicle_name)
