Hi Arif,
Unfortunately it is not possible to use Google map as a base map in Pix4Dmapper.
You can choose between Satellite or Maps basemap :
It has been suggested to our developers for future implementation. But at the moment we cannot guarantee anything.
However, it is possible to display Google maps for image acquisition in Pix4Dcapture for both iOS and Android.
Please avoid duplicate posts/comments (as you already asked it here)
Best,
