Embodiment Construction

[0049] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments do not constitute a limitation to the present invention.

[0050] This embodiment provides a real-time image tracking method for vehicles based on GPS trajectory data, which is used to implement real-time image tracking of designated vehicles through images of monitoring points. This method does not require the purchase and installation of cumbersome tracking equipment and can be well controlled. cost.

[0051] Such as figure 1 As shown, the real-time image tracking method for vehicles based on GPS trajectory data includes:

[0052] Step S1. Obtain GPS trajectory data collected in the last t seconds (for example, 10 seconds) during the driving of the vehicle, arrange the GPS trajectory data in chronological order, and store the longitude and latitude in the GPS trajectory data in the sequence after ar...

Abstract

The invention discloses a vehicle real-time image tracking method based on GPS trajectory data, comprising the following steps: estimating positions of vehicles at a future time point by using historical GPS trajectory data, pre-selecting monitoring points where vehicles may possibly be captured according to the estimated position information to narrow the scope of investigation and prepare for capture in advance so as to enhance the capture effect, detecting the images of the monitoring points by a deep convolutional neural network model with high real-time, filtering the vehicle-free monitoring points, and storing the images taken by the monitoring points with vehicles is, thereby realizing the no-delay tracking of images.

Description

Technical field [0001] The invention relates to the technical field of vehicle tracking, in particular to a real-time image tracking method of a vehicle based on GPS track data. Background technique [0002] An unmanned car is a smart car that senses the road environment through the on-board sensor system, automatically plans the driving route and controls the vehicle to reach a predetermined goal. It uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle location, and obstacle information obtained by the perception, so that the vehicle can safely and reliably drive on the road. [0003] With the development of unmanned vehicles, the testing of unmanned vehicles has gradually developed. However, most of the existing vehicle test systems are manual operation tests and lack automated tools. [0004] The testing of unmanned vehicles is an important link that affects the development of u...
