WIFI intersection calibration method

The invention discloses a WIFI intersection calibration method comprising the steps that step one, the first time of WIFI signal measurement is performed on a POI, and acquisition data are expressed by using a JSON format; step two, the second time of WIFI signal measurement is performed on the POI, and the acquisition data are expressed by using the JSON format; and step three, intersection calibration is performed, the intersection of the two times of acquisition data is taken to act as calibration data, and the calibration data are described by using an XML format. The advantages of the WIFI intersection calibration method are that "ineffective WIFI" data can be greatly reduced, accuracy of location calculation can be enhanced and can be basically guaranteed for over 90% and aging speed of the data can be greatly reduced. 本发明公开了种WIFI交集标定方法，其包括：步骤，对POI进行第次WIFI信号测量，使用JSON格式来表示采集数据；步骤二，对POI进行第二次WIFI信号测量，使用JSON格式来表示采集数据；步骤三，交集标定，取两次采集数据的交集作为标定数据，并使用XML格式来描述。本发明的优点在于能够大幅减少"无效WIFI"数据，提高位置解算的准确率，基本能够保证在90%以上，并且数据
