Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] Such as figure 1 As shown, in the vehicle running process, the present invention comprises the following steps:
[0033] 1) Set up a signal point recorder in the navigation system, and automatically record a signal point information after the signal point recorder starts;
[0034] 2) The signal point recorder records and refreshes the signal points in real time, and completes the adding process;
[0035] 3) Based on the time criterion and the distance criterion, the rationality judgment is made on the signal point sequence of the added path;
[0036] 4) In the embedded navigation device, the Kalman filter and the point-sequence thinning algorithm are used to perform real-time smoothing processing on the path-adding shape points.
[0037] The specific implementation methods of the above steps are described as follows:
[0038] Step 2) The re...
