如何把全景照片转换成视频opencv

要将全景照片转换为视频，可以使用OpenCV库中的Python编程语言。具体步骤如下：

1.导入必要的库：

import cv2
import numpy as np

2.读入全景照片并确定视频分辨率：

panorama = cv2.imread('panorama.jpg')
height, width = panorama.shape[:2]
size = (width, height)

3.创建一个VideoWriter对象以保存视频：

fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi', fourcc, 20.0, size)

其中，fourcc参数是视频编码器，20.0是帧率，size是视频分辨率。

4.将全景照片分割成若干个小图像：

num_frames = 100 #视频的帧数
step = width // num_frames
frames = []
for i in range(num_frames):
    left = i * step
    right = (i+1) * step
    frame = panorama[:, left:right, :]
    frames.append(frame)

5.将每个小图像写入视频：

for i in range(len(frames)):
    out.write(frames[i])

6.释放资源：

out.release()

完整代码如下：

import cv2
import numpy as np

panorama = cv2.imread('panorama.jpg')
height, width = panorama.shape[:2]
size = (width, height)

fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi', fourcc, 20.0, size)

num_frames = 100
step = width // num_frames
frames = []
for i in range(num_frames):
    left = i * step
    right = (i+1) * step
    frame = panorama[:, left:right, :]
    frames.append(frame)

for i in range(len(frames)):
    out.write(frames[i])

out.release()
