Abstract: Methods, systems, and computer program product for generating location fingerprint data for a venue are described. A sampling device surveying a venue can move inside the venue. While the sampling device moves, the sampling device can record environmental readings including, for example, strengths of signals from multiple radio signal sources. The sampling device can take the recording at fixed or various time intervals. Meanwhile, the sampling device can determine, based on a starting point and motion sensor readings, an estimated location of the mobile device for each time the sampling device takes the recordings. The sampling device can display a motion path of the estimated locations and a user interface item for receiving a user input for correcting the estimated locations. The sample device can tag the recorded environmental readings with the corrected locations, and submit the tagged readings to a server for determining a location fingerprint for the venue.

Abstract translation: 描述了用于为场地生成位置指纹数据的方法，系统和计算机程序产品。 调查场地的抽样装置可以在场地内移动。 当取样装置移动时，采样装置可以记录环境读数，包括例如来自多个无线电信号源的信号的强度。 采样设备可以固定或不同的时间间隔进行记录。 同时，采样装置可以基于起点和运动传感器读数，每次采样装置进行记录时，确定移动装置的估计位置。 采样设备可以显示估计位置的运动路径和用于接收用户输入的用户界面项目，用于校正估计位置。 样品设备可以用修正的位置标记记录的环境读数，并将标记的读​​数提交给服务器，以确定场地的位置指纹。
