A kind of intelligent car search method and system based on car networking

Abstract

The invention discloses an intelligent car-finding method and system based on the Internet of Vehicles. The method includes: obtaining the signal-to-noise ratio information of the vehicle positioning information and judging whether it is lower than a threshold value, if so, saving and uploading, and recording the current time t1; judging Whether the car is turned off, if so, detect whether the car has moved; if the car has not moved, read the driving image n seconds before the car is turned off; confirm that the car is turned off and take a picture every preset time t within the preset time period Compress and save; extract the key frame image and combine it with the image obtained after turning off the engine to deduplicate and store and upload; obtain the identification information and combine the deduplicated key frame image and the image obtained after turning off the engine to form an auxiliary video file; generate a parking position report and Push it to the mobile terminal; check the parking location report, and find the vehicle according to the shortest car-finding path. The invention extracts key images from parking images, identifies identification information, reduces traffic consumption, saves browsing time, and is convenient and accurate.

Description

technical field [0001] The present invention relates to the field of the Internet of Vehicles, and more specifically, to an intelligent car finding method and system based on the Internet of Vehicles. Background technique [0002] With the development of society, the number of car ownership is increasing year by year, and car travel has become the main choice of people. However, with the increase of cars, there are fewer open-air or outdoor parking lots, and most of them are underground parking lots. Generally, GPS is used to realize vehicle parking. The location of the parking lot and the current location of the user are located, and then the path is planned for the user according to the location of the user and the location of the vehicle in the parking lot, so that the user can quickly find the location of the vehicle, but GPS positioning There is a certain range of errors, and some parking lots have weak or no GPS signals. For large and complex parking lots lacking refer...
