Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0034] See figure 1 , figure 1 The discrete trajectory analysis method provided by the embodiment of the present application is shown. The method can be executed by an electronic device. The electronic device can be a terminal device or a server. The method specifically includes the following steps S110 to S140:

[0035] Step S110, determine the search direction coordinate axis according to the coordinate values ​​of the plurality of main track points of the main discrete track.

[0036] The search direction coordinate axis is used to reflect the overall extension direction of the main discrete trajectory. The main discrete trajectory may be the discrete trajectory of the movement of the vehicle driven by the user in the ADAS, which is composed of multiple main trajectory points, and the multiple ...

Abstract

The invention provides a discrete track analysis method and device, electronic equipment and a readable storage medium. The method comprises the steps of determining a search direction coordinate axisaccording to the coordinate values of a plurality of main track points of a main discrete track; obtaining a first target track point of the target discrete track and a coordinate value of the firsttarget track point in the search direction coordinate axis; according to the search direction coordinate axis, screening out a primary main track point from the plurality of main track points; and determining the distance between the first target track point and the main discrete track according to the primary main track point and the adjacent main track points. Compared with the prior art, the method is small in calculation amount and high in calculation efficiency.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a discrete trajectory analysis method, device, electronic equipment and readable storage medium. Background technique [0002] In the Advanced Driving Assistant System (ADAS for short), it is often necessary to calculate the distance between the discrete trajectory of the vehicle and the discrete trajectory of the target. [0003] In the prior art, when calculating, it is often to calculate the distance between each track point in one of the discrete tracks and each track point in another discrete track, and then take the shortest distance among the above-mentioned multiple distances; Or every time a distance is calculated, it is compared with a preset distance threshold, and a distance smaller than the preset distance threshold is taken as the distance between two discrete trajectories. The existing calculation method has a large amount of calculation and low...
