Embodiment Construction
[0031] In the calculation and analysis of road conditions based on floating cars, it is necessary to preprocess the original floating car data to filter out normal data that can be used for subsequent calculations. The present invention improves the method of the prior art, and proposes a data preprocessing device and method, which can utilize the front and back relationship of each data point in the floating car data, and filter out from the original floating car data that are easy to be regarded as normal data. The temporary parking data points of the data, so as to avoid the interference of the temporary parking data points on the subsequent road condition calculation and analysis, reduce the calculation intensity, and improve the calculation speed and accuracy.
[0032] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention is not limited to the following exemplary embodiments. ...
