Smart_GrabImage_WebCamera

Header:	ThirdPartySdk.h
Namespace:	fil

Captures an image from a smart camera. Allows for remote access to the runtime system.

Syntax

bool fil::Smart_GrabImage_WebCamera
(
	Smart_State& ioState,
	const fil::SmartIPAddress& inIpAddress,
	ftl::Optional<int> inDeviceID,
	fil::Image& outImage,
	bool& outIsRemote
)

Parameters

Name	Type	Default	Description
ioState	Smart_State&		Object used to maintain state of the function.
inIpAddress	const SmartIPAddress&		IP address of the runtime system
inDeviceID	Optional<int>	NIL	Tries to find the camera in all available IDs (UserID, VendorName, ModelName...)
outImage	Image&		Captured frame
outIsRemote	bool&		Specifies whether the program is currently executed on the runtime (True) or development (False) system

Hints

Check the IP address of your runtime system (e.g. using the "ipconfig" command) and set it to the inIpAddress input.
Run the program on you runtime system and the camera filter will acquire images directly on it.
Run the program on your development machine (e.g. your laptop) connected to the same Ethernet and the camera filter will receive images through a connection with the runtime system.
