您对PicamCameraID结构的定义不正确：
sensor_name并且
serial_number是arrays：
"""struct PicamCameraID { PicamModel model; PicamComputerInterface computer_interface; pichar sensor_name[PicamStringSize_SensorName]; pichar serial_number[PicamStringSize_SerialNumber]; };"""import ctypes as cPicamStringSize_SensorName = PicamStringSize_SerialNumber = 64PicamModel = PicamComputerInterface = c.c_intpichar = c.c_charclass PicamCameraID(c.Structure): _fields_ = [("model", PicamModel), ("computer_interface", PicamComputerInterface), ("sensor_name", pichar * PicamStringSize_SensorName), ("serial_number", pichar * PicamStringSize_SerialNumber)]似乎第二个参数只是一个字符串，因此您无需对其进行应用
pointer()。这是功能的
ctypes原型
Picam_ConnectDemoCamera()：
"""Picam_ConnectDemoCamera(PicamModel model, const pichar* serial_number, PicamCameraID* id)"""pichar_p = c.c_char_p # assume ' '-terminated C stringsPicam_ConnectDemoCamera.argtypes = [PicamModel, pichar_p, c.POINTER(PicamCameraID)]Picam_ConnectDemoCamera.restype = c.c_int # assume it returns C int
调用它：
picam_id = PicamCameraID()rc = Picam_ConnectDemoCamera(2, "serial number here", c.byref(picam_id))print(rc)print(picam_id.sensor_name.value) # C stringprint(picam_id.sensor_name.raw) # raw memory
