Embodiment Construction

[0045] see figure 1 , which is a flow chart of a method for optimizing a vehicle track display provided by an embodiment of the present invention, the method includes the following steps:

[0046] Step S100: Obtain vehicle track data and total track display time.

[0047] In the embodiment of the present invention, the collection of vehicle trajectory data is completed by an intelligent terminal installed on the vehicle. The intelligent terminal will irregularly collect trajectory point data according to the driving condition of the vehicle. According to the actual driving condition of the vehicle, the distance between adjacent trajectory points The time intervals are different. For example, when the vehicle is turning, the collection frequency of the vehicle's trajectory points is greater than that of the vehicle when it is straight, so as to ensure that the collected and received vehicle trajectory can be close to the actual vehicle driving route. After the smart terminal c...

Abstract

The invention discloses a method and a device for optimizing vehicle track display, and a terminal system. The optimization method comprises the following steps: obtaining vehicle track data and a total track display time; calculating an actual total track time and an acquisition time difference between adjacent track points; calculating the display time weight of the adjacent track points; calculating the display times of the adjacent track points; fitting the coordinates of the track points to form a track curve, and calculating an actual distance between the adjacent track points; calculating the display speed of the adjacent track points; and displaying the vehicle track along the track curve. The display time weight of the adjacent track points is calculated to distribute the track display time according to the weight for every track formed by the two adjacent track points, and the track display speed is calculated according to the track display time, so the track display speed correspondingly changes according to the speed change during vehicle running, and the transformation state between rapid acceleration and rapid deceleration of the vehicle can be visually observed on aamp.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a vehicle trajectory display optimization method, device and terminal system. Background technique [0002] Global Positioning System (Global Positioning System; hereinafter referred to as: GPS) is a global, all-weather and continuous satellite radio navigation system that can provide real-time three-dimensional coordinates, three-dimensional speed and high-precision time information. Because GPS has the advantages of high positioning accuracy, fast speed and wide range, the application of GPS is very extensive, covering almost all fields of the national economy. [0003] According to the characteristics of GPS, solutions such as positioning monitoring based on GPS and Geographic Information System (GIS for short) are widely used. The positioning supervision solution is to install GPS receivers on various carriers that need supervision, such as: personnel ...
