这个错误提示是因为 `outframe` 是一个三维数组，但是在赋值时使用了三个索引，导致维度不匹配。你可以尝试修改代码如下：

outframe = hdmi_out.newframe()
outframe[:,:,0] = frame[:,:]
outframe[:,:,1] = frame[:,:]
outframe[:,:,2] = frame[:,:]
hdmi_out.writeframe(outframe)

这样就可以将灰度图像 `frame` 复制到 `outframe` 的所有通道中，然后输出到 HDMI。

这个错误提示表明你的 `outframe` 的维度为 2，而你尝试对其进行三维索引。你可以通过 `outframe.shape` 查看 `outframe` 的维度，然后确认你对其进行的索引是否正确。如果你想将灰度图像复制到 `outframe` 的第三维度上，你需要将其转换为彩色图像。可以通过 `cv2.cvtColor()` 将灰度图像转换为彩色图像。例如：

color_image = cv2.cvtColor(gray_image, cv2.COLOR_GRAY2BGR)
outframe[0:480,0:640,:] = color_image[0:480,0:640,:]

这样就可以将灰度图像复制到 `outframe` 上了。

这个问题的错误提示是因为你的 `outframe` 数组是二维的，而你试图使用三个索引访问它的某个元素。

你可以修改代码，将 `outframe` 数组改为三维的，例如：

outframe = np.zeros((480, 640, 3), dtype=np.uint8)

然后再进行赋值：

outframe[0:480, 0:640, :] = frame[0:480, 0:640, :]

这样就可以正确地将 `frame` 数组中的内容赋值到 `outframe` 数组中了。
