問題

無法打印actual_exposure不知怎么回事

print(color_frame.get_frame_metadata(rs.frame_metadata_value.actual_exposure))

結果：

D:\20191031_tensorflow_yolov3\python\python.exe D:/2_pycharm測試項目/200108_測試獲取Intel_Realsense_options參數/200110_測試攝像頭實時獲取曝光值.py 攝像頭838212073161初始化成功 Traceback (most recent call last):File "D:/2_pycharm測試項目/200108_測試獲取Intel_Realsense_options參數/200110_測試攝像頭實時獲取曝光值.py", line 52, in <module>print(color_frame.get_frame_metadata(rs.frame_metadata_value.actual_exposure)) RuntimeError: metadata not availableProcess finished with exit code 1

另外，auto_exposure、auto_white_balance_temperature、exposure_roi_bottom 也不行，不知咋回事
