The indoor navigation method for the indoor parking lot comprises the following steps: (1) based on a parking lot parking space navigation platform, the platform comprises a front-end mobile terminal and a background system, and the parking lot parking space navigation platform comprises a mobile terminal, a background management terminal, a hardware equipment terminal, a third-party position service and a cloud service; the method is characterized in that (1) a hardware equipment terminal comprises a parking space detection unit, a communication unit and a microcontroller, each parking space is provided with an infrared detection module, and parking space information, namely the existence condition of a vehicle, is sensed through an infrared sensor module or a camera; (2) a parking lot indoor navigation step: after a user arrives at the parking lot, checking a current idle parking space distribution diagram in the parking lot by using a mobile terminal, after a parking space is selected for parking, acquiring license plate information by a camera, binding a license plate and the parking space information, and uploading the license plate and the parking space information; and during vehicle searching, the mobile terminal sends the optimal vehicle taking route to the mobile user side according to the license plate number and the current position. And the functions of quick parking space searching, indoor navigation and reverse vehicle searching are realized.

室内停车场室内导航方法，(1)基于停车场车位导航平台，平台包括前端移动端和后台系统的实现，停车场车位导航平台包括移动端、后台管理端、硬件设备终端、第三方位置服务和云服务这4个部分组成；1)硬件设备终端包括车位检测，通信单元、微控制器、每个车位均设有红外检测模块，通过红外传感器器模块或再加摄像头感知车位信息，即车辆的存在状况情况；(2)停车场室内导航步骤，用户到达停车场后，利用移动终端查看停车场内当前空闲车位分布图，选好车位停车后，摄像头获取车牌信息，将车牌和车位信息绑定后上传；寻车时，移动终端根据车牌号和当前位置，将最佳取车路线发送到移动用户端。实现快速的车位查找、室内导航、反向寻车功能。
