To provide a visitor quantity estimation device and the like capable of estimating the quantity of visitors to a store in real time (with high temporal resolution) and accurately (with high spatial resolution).SOLUTION: The visitor quantity estimation device that estimates the number of visitors of stores lined up along a road includes: a store database storing logo images in association with respective stores; vehicle information reception means that receives a captured video in a traveling direction from a moving vehicle; store image recognition means that image-recognizes logo images in the store database from the captured video to identify a store; vehicle image recognition means that image-recognizes a vehicle reflected on a side of the road from the captured video in which the logo image is reflected; and visitor quantity estimation means that estimates, as the quantity of visitors to the store, a number of recognized vehicles that have been image-recognized from the captured video in which the logo image is reflected.SELECTED DRAWING: Figure 2 【課題】リアルタイムに（時間解像度が高い）、店舗の訪問者数を正確に（空間解像度が高い）推定することができる訪問者数推定装置等を提供する。【解決手段】道路側面に並ぶ店舗の訪問者数を推定する訪問者数推定装置において、店舗毎に、ロゴ画像を対応付けて記憶した店舗データベースと、走行中の車両から、進行方向の撮影映像を受信する車両情報受信手段と、撮影映像から、店舗データベースのロゴ画像を画像認識し、店舗を特定する店舗画像認識手段と、当該ロゴ画像が映り込む撮影映像から、道路側面に映り込む自動車を画像認識する自動車画像認識手段と、当該ロゴ画像が映り込む撮影映像から画像認識された当該自動車の認識台数を、当該店舗の訪問者数として推定する訪問者数推定手段とを有する。【選択図】図２
