这个错误是由于 `outframe` 和 `frame` 的维度不一致造成的。从错误信息可以看出,`outframe` 是一个二维数组,而你尝试使用三个索引来访问它。一种可能的解决方法是使用 `np.dstack()` 函数将 `frame` 中的三个通道组合成一个三维数组,然后将它赋值给 `outframe`,如下所示:
```python
outframe = np.dstack((frame, frame, frame))
hdmi_out.writeframe(outframe)
```
这样,`outframe` 就与 `frame` 具有相同的维度,可以通过相同的索引方式进行访问。

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:
```python
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。
