I had worked in this industry for the past 5 years. I tried to start 3 years ago a company in this sector (outdoor billboard analytics). I will tell you one word: "Go away !".

The problem isn't the technology you use (facial recognition is working well but is too expensive). The average technology used to measure billboards is phone gps positions sent by applications that have contracts with data providers.

It's working pretty well but the sector is moving really slowly (in the US is much better than in Europe where all the services are corrupted). Nobody in the industry wants to change the method because they are selling the same amount of ODV (views) for 20 years and they don't want to have the allowed budgets advertisers are given to them.
