You should check the tool gdal_grid. http://www.gdal.org/gdal_grid.html.

Differently, you can either open the csv in qgis as a shapefile as done here:

OR directly in python

https://gis.stackexchange.com/questions/202922/create-shapefile-from-csv-using-ogr-and-python 

Subsequently, you can use gdal_translate to rasterize the vector based on all the necessary fields http://www.gdal.org/gdal_rasterize.html.

Dear experts,
