    No it's not... that relay uses about 35mA to drive the coil. If you get that current straight from the Pixhawk I/0 pin you will damage the Pixhawk. You need to use a transistor or a Solid state relay.

    No you won't damage the Gopro, but you will damage the pixhawk as a relay will use more than the allowed 15mA you can get from the I/O pins. 

    You have to use a solid state realy like this http://www.jaycar.com.au/pcb-mount-solid-state-dil-relay/p/SY4090 or use an alternative solution like the Pico switch suggested.

    I already open the Gopro and get out two wires for power switch just need to connect it to relay to operate throw Pixhawk

    The camera has it's own power throw it's battery ,

    the relay function is just switch to close for 3 second and release .

    If you don't want to open the GoPro and risk damaging it, there is a way to control it using the HD bus port.
    If you google for "gopro hd bus", you can find a lot of sites showing how to control the GoPro using the HD bus, for example: http://benlo.com/msp430/GoProController.html
