Narrative:

I was flying around hacienda heights to check out the location of my house with my family members in-flight. I am just using the estimated elevation from el monte airport to estimate my field elevation. Due to the altimeter only shown the MSL but not AGL; I mis-estimated the minimum altitude on the congested area. After I checked out my house; suddenly; I found out that there was a black helicopter flying towards me. I felt that helicopter was a little bit strange. I just pulled my yoke to climb back again instantly. Then I continued to fly back to my home airport (el monte airport). At that moment; the cops contacted the tower frequency to talk to me; said that I violated the far from flying too low.
