在Python中调用名为`CR_RegisterEventCallback`的函数,并实现`ICallback`接口,可以使用以下代码示例:
```python
from ctypes import cdll, c_int, c_void_p, CFUNCTYPE, POINTER, Structure
# 加载动态链接库
lib = cdll.LoadLibrary('your_library_path')
# 定义结构体和枚举
class CR_EventID:
CR_EVT_SERVER_DISCONNECTED = 0
CR_EVT_DETR_DISCONNECTED = 1
CR_EVT_TEMPERATURE_INFO = 2
CR_EVT_NEW_FRAME = 3
CR_EVT_CALIBRATION_IN_PROGRESS = 4
CR_EVT_CALIBRATION_FINISHED = 5
CR_EVT_ACQ_STAT_INFO = 6
class CR_Event(Structure):
_fields_ = [
('nDetrIdx', c_int),
('nWidth', c_int),
('nHeight', c_int),
('nPixelDepth', c_int),
('pData', c_void_p),
]
class CR_AcquisitionStatInfo(Structure):
_fields_ = [
('nTotalFrameNum', c_int),
('nLostFrameNum', c_int),
('fStatFrameRate', c_float),
('fTransmissionSpeed', c_float),
('nAcqDuration', c_longlong),
]
# 定义回调函数原型
CallbackFunc = CFUNCTYPE(None, c_int, POINTER(CR_Event))
# 定义函数原型
lib.CR_RegisterEventCallback.argtypes = [c_int, CallbackFunc]
lib.CR_RegisterEventCallback.restype = c_int
# 实现回调函数
def callback_func(nEventID, pEvent):
# 处理事件的逻辑
if nEventID == CR_EventID.CR_EVT_SERVER_DISCONNECTED:
print("Server disconnected")
elif nEventID == CR_EventID.CR_EVT_DETR_DISCONNECTED:
print("Detector disconnected")
elif nEventID == CR_EventID.CR_EVT_TEMPERATURE_INFO:
print("Temperature info received")
elif nEventID == CR_EventID.CR_EVT_NEW_FRAME:
print("New frame received")
elif nEventID == CR_EventID.CR_EVT_CALIBRATION_IN_PROGRESS:
print("Calibration in progress")
elif nEventID == CR_EventID.CR_EVT_CALIBRATION_FINISHED:
print("Calibration finished")
elif nEventID == CR_EventID.CR_EVT_ACQ_STAT_INFO:
# 将pData强制转换为CR_AcquisitionStatInfo指针,并解引用获取结构体对象
acq_stat_info = cast(pEvent.contents.pData, POINTER(CR_AcquisitionStatInfo)).contents
print("Acquisition stat info received:", acq_stat_info.nTotalFrameNum, acq_stat_info.nLostFrameNum)
# 调用函数
def CR_RegisterEventCallback(nDetrIdx):
result = lib.CR_RegisterEventCallback(nDetrIdx, CallbackFunc(callback_func))
return result
```
请注意,这里的`your_library_path`应该替换为包含`CR_RegisterEventCallback`函数的动态链接库的实际路径。另外,你可能需要根据实际情况修改函数原型的参数和返回类型。在这个例子中,`nDetrIdx`是整数类型的参数。回调函数`callback_func`用于处理不同事件类型,并根据需要进行逻辑处理。
