Python 制作全息图金字塔

Question

我正在研究全息视觉。我想把 4 张图片放到黑屏上。

我写了这段代码：

import numpy as np
import cv2
from screeninfo import get_monitors

if __name__ == '__main__':
    screen = get_monitors()[0]
    print(screen)
    width, height = screen.width, screen.height

    image = np.zeros((height, width, 3), dtype=np.float64)
    image[:, :] = 0  # black screen
    img = cv2.imread("newBen.png")
    p = 0.25
    w = int(img.shape[1])
    h = int(img.shape[0])
    new_img = cv2.resize(img, (w, h))
    image[:h, :w] = new_img
    window_name = 'projector'
    cv2.namedWindow(window_name, cv2.WND_PROP_FULLSCREEN)
    cv2.moveWindow(window_name, screen.x - 1, screen.y - 1)
    cv2.setWindowProperty(window_name, cv2.WND_PROP_FULLSCREEN,
    cv2.WINDOW_FULLSCREEN)
    cv2.imshow(window_name, image)
    cv2.waitKey()
    cv2.destroyAllWindows()

但我的图像看起来像这样。

我该如何解决？

Answer 1

普通RGB图像的dtype是uint8，不是float64。

image = np.zeros((height, width, 3), dtype=np.uint8)

顺便说一句：您不必设置 image[:, :] = 0 # black screen。 np.zeros.
