Embodiment 1

[0033] Such as figure 1 A kind of traffic violation intelligent voice capture method shown, comprising:

[0034] Step S-0, collecting driving data and driving images in a fixed time period T and storing them in the data center. The vehicle position information I, vehicle speed information v, vehicle acceleration information a, vehicle driving direction information d and current time information t are collected in real time by the mobile vehicle terminal installed on the vehicle. The above information set x(t)={l, v, a, d} collected by the mobile vehicle terminal at time t is used as the driving data set at time t and stored in the data center. At the same time, the vehicle-mounted terminal also includes a recording device such as a camera for recording images in front of the vehicle. The recording device records the image in front of the vehicle in real time and stores it in the data center while the vehicle is running. The data center can be a storage device such as a loca...

Embodiment 2

[0053] The present invention also provides an intelligent voice capture system for traffic violations, which includes a voice detection device, a camera, a data center, and a controller, and uses the capture method in Embodiment 1 to perform capture.

Abstract

The invention relates to the technical field of the traffic violation evidence, and especially relates to a traffic violation intelligent voice snapshot method and system. The method comprises the following steps: step S-1, extracting a traveling data sequence when detecting a voice instruction, wherein the traveling data sequence comprises vehicle location information 1, vehicle speed informationv, vehicle acceleration information a, driving direction information d and time information t; step S-2, computing snapshot weight W based on the voice instruction and the travelling data sequence, and entering the step S-3 when the snapshot weight W is greater than the snapshot weight threshold Ws; step S-3, performing traffic violation snapshot, wherein the snapshot weight W is the sum of at least one of the speed weight w2, the location weight w3 and the acceleration weight w4, and the voice weight w1. By integrating the location, the speed, the acceleration and multi-element information of the vehicle, the vehicle violation information of the vehicle can be sensed, and the recognition accuracy rate of the snapshot is improved.

Description

technical field [0001] The invention relates to the technical field of evidence collection for traffic violations, in particular to an intelligent voice capture method and system for traffic violations. Background technique [0002] With the sharp increase in the number of cars in our country, urban road traffic congestion is becoming more and more serious, which has caused serious road rage ("road rage" is driving anxiety, which refers to the driver's swearing and random changes in driving due to bad road conditions. , forced overtaking, running yellow lights, etc.). Many drivers are prone to irregular driving behaviors in the face of bad traffic conditions; at the same time, irregular driving behaviors will also cause other drivers, especially road rage drivers, to attack, leading to a vicious circle. Irregular driving behaviors such as malicious congestion, dangerous overtaking, random lane changes, etc., are prone to minor traffic accidents such as vehicle scratches and...
