occupancygrid保存为图片

要将occupancy grid保存为图片，您可以使用Python中的OpenCV库或Pillow库。以下是使用Pillow库将occupancy grid保存为图片的示例代码：

from PIL import Image

# assume occupancy grid is stored in a numpy array called "grid"
# convert grid values to 0-255 grayscale values
grid_img = (grid * 255).astype('uint8')

# create image from grid and save it
img = Image.fromarray(grid_img, mode='L')
img.save('occupancy_grid.png')

这将把occupancy grid转换成灰度图像，并将其保存为名为"occupancy_grid.png"的文件。您可以根据需要更改文件名和路径。
