Android-based low-cost waiting driving reminding system

Abstract

The invention provides an Android-based low-cost waiting driving reminding system, which comprises a video acquisition module, a video processing module, a GPS speed measurement module, a user graphic interface module, a voice prompting module and a display module, wherein the video acquisition module is used for acquiring original image data captured by an Android equipment camera; the video processing module is used for carrying out background subtraction and other operation on the original image data and judging the driving state of the vehicle and the driving state of a former vehicle; the GPS speed measurement module is used for acquiring the speed of the vehicle in real time, when the vehicle speed is lower than a set threshold, the video processing module is started, or otherwise, the video processing module is closed to save operation resources; and the display module and the voice prompting module are used for providing dynamic information of the former vehicle in real time via the user graphic interface module. The system of the invention is based on low-cost Android platform development, and has the advantages of low cost, integration, one-key mounting, simple maintenance, and convenient and quick operation.

Description

technical field [0001] The invention relates to the fields of digital image processing and driving assistance, in particular to an Android-based low-cost parking and waiting driving reminder system. Background technique [0002] With the rapid development of modern cities, the number of cars in China continues to increase, and cars have gradually integrated into people's lives. While cars bring us great convenience, they also bring problems such as traffic jams and parking difficulties, especially On urban arterial roads, congestion problems often occur. When waiting for traffic lights on congested roads or intersections, drivers need to pay attention to the start and stop status of the vehicle in front at all times to ensure smooth and orderly traffic flow. exacerbate road congestion. [0003] After searching the literature of the prior art, it is found that the Chinese utility model patent application number: 201020296525.1 discloses a system for detecting the relative d...

AI Technical Summary

Problems solved by technology

However, in order to accurately obtain the relative distance from the vehicle in front, there are certain requirements for the sensor. For visual ranging, it is necessary to obtain image depth information. Ordinary monocular cameras, such as the cameras on common Android phones, cannot Obtaining image depth information requires the use of a binocular camera or a stereo vision camera, which undoubtedly increases the cost of the system. For the parking waiting reminder system, most users are not willing to invest too much money, and there is also the accompanying professional installation , maintenance issues, etc., so the operability and practicability of the above patents are not strong
