start_capturing
Starts to process images consecutively.
def start_capturing(self, template_name: str = "", wait_for_thread_exit: bool = False) -> Tuple[int, str]:
Parameters
template_name Specifies a CaptureVisionTemplate to use for capturing.
wait_for_thread_exit Indicates whether to wait for the capture process to complete before returning.
Remarks
- There are two types of
CaptureVisionTemplate: the preset ones which come with the SDK and the custom ones that get initialized when the user calls InitSettings / InitSettingsFromFile. - Please be aware that the preset
CaptureVisionTemplateswill be overwritten should the user callInitSettings/InitSettingsFromFileand pass his own settings. - If parameter
template_nameis not specified, the preset one named ‘Default’ will be used. However, if the preset ones have been overwritten as described above, the firstCaptureVisionTemplatefrom the user’s own settings will be used instead.
Return Value
Returns a tuple containing following elements:
error_code<int>: The error code indicating the status of the operation.error_message<str>: A descriptive message explaining the error.
