The utility model relates to an automatic control technical field, in particular to synchronous photographing system that car range finding tested speed.
Background
In recent years, with the continuous improvement of living standard of people, the number of motor vehicles is increasing, more and more families use automobiles as transportation tools, although the automobiles can greatly meet the travel requirements of people, the road traffic condition is worse, and the following phenomena of serious traffic accidents and harming traffic and transportation safety are more and more severe. Automobile collision accidents occur occasionally, and more owners pay attention to trip safety. When a car touches a pedestrian or rear-end collisions occur between front and rear cars, the public security department mainly judges accident responsibility by on-site observation and road monitoring video, and a driving recorder arranged in the car can also play a certain role in judging the accident responsibility.
However, the monitoring camera and the driving recorder always have some dead angles which cannot be observed, and the video recordings acquired by the monitoring camera and the driving recorder can only qualitatively present the process of accident occurrence, and lack accurate and quantitative data analysis. When law enforcement officers identify accident responsibilities according to the video recordings, a large amount of time is often spent on repeatedly watching the video recordings, even the video recordings are analyzed frame by frame, and the requirement on professional level of the law enforcement officers is high. Even so, it is sometimes difficult to conclude that both parties to the accident are unanimous. Somebody has just drilled the vacancy and intentionally touched porcelain with vehicles running at a traffic intersection at a slow speed, thereby achieving the purpose of breaking out money and money.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention easier to be clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
As shown in figures 1 and 2, the synchronous photographing system for measuring the distance and the speed of the automobile 1 comprises a measuring module, a camera module and a storage module, wherein the measuring module comprises a distance measuring element 2 and a speed measuring element, the distance measuring element 2 is installed in the front and the side of the automobile 1 and used for detecting the distance between an automobile body and the front and the distance between the automobile body and an obstacle, and the distance measuring element 2 is one or more of an ultrasonic sensor, a laser sensor, an infrared sensor and a microwave radar. If an ultrasonic sensor is used, the time from sending a detection sound wave signal to receiving echo is measured, and the distance between the model car and the front obstacle can be calculated according to the propagation speed (about 340 m/s) of the sound wave in the air, wherein the calculation formula is as follows:
distance (echo received time-detected sound wave emitting time) sound speed/2.
The speed measuring element is arranged near the rotating shaft of the automobile 1 and used for detecting speed data, and the speed measuring element is a Hall speed measuring sensor or the speed data is directly obtained from an instrument panel of the automobile 1. In order to meet the actual requirement, the vehicle speed is lower when the driver passes through the intersection for preventing porcelain collision, generally less than 36km/h (namely 10m/s), and the vehicle speed data is converted into m/s.
The camera module comprises a camera 3, the camera 3 is arranged in front of and at the side of the automobile 1, the model of the camera 3 is OV5640, the resolution of the camera 3 is 500 ten thousand pixels, and the camera frame rate is set to be 50-60 frames/s;
the storage module comprises an SD card 5, an HC06 unit and an ESP8266 unit, the SD card 5 is used for synchronously storing data information acquired by the measurement module and the camera module, the memory size of the SD card 5 is 32G, and the access speed of the SD card 5 is 80 MB/s; for convenience of viewing, the HC06 unit sends data information to the bound mobile devices through a bluetooth channel, and the ESP8266 unit sends the data information to the cloud server through a WIFI channel; the measuring module, the camera module and the storage module are all connected to the core processor 4.
The working principle is as follows:
when the distance between the vehicle body and the obstacle is smaller than a safety threshold (the threshold can be set according to actual needs, sensor response speed and other factors), the camera 3 is automatically started to shoot a static photo at each moment in the accident process at the speed of 50 frames to 60 frames per second, and the data of the instantaneous driving speed of the vehicle, the distance between the vehicle body and the obstacle, the time of shooting the photo and the like are synchronously formed into a complete data record and stored in the storage module.
Normally, the driver usually takes deceleration measures when the distance between the vehicle 1 and the pedestrian in the driving direction is less than a safety threshold. When the vehicle running speed is reduced to 0, that is, it is already in a stopped state, if the distance between the vehicle and the pedestrian is still greater than 0 at this time, it is judged that the vehicle does not touch the pedestrian during running. If the vehicle has stopped and the distance between the vehicle and the pedestrian is still decreasing, so that zero distance contact occurs, it can be concluded that the pedestrian is actively approaching the stopped vehicle, and the driver should not be responsible for the accident, so that the person who cares about "porcelain collision" cannot achieve the purpose of corruption.
When the vehicle starts on a steep slope, if the driver slips off the slope due to improper operation, the rear-end collision accident occurs with the vehicle which is not started at the rear, and by utilizing the technology of the patent, the driver of the vehicle at the rear can be judged to not bear main responsibility more simply and quickly even under the condition of no monitoring video.
The utility model can provide quantitative basis for the judgment of automobile accidents by installing elements such as distance measurement, speed measurement, photographing and storage; when detecting that the automobile body and the barrier are smaller than the safe distance, the distance measurement, the speed measurement and the photographing operation are continuously executed, the three data at each moment are synchronously combined and stored in the storage module, and the person responsible for the accident can be effectively judged when the accident happens.
The utility model discloses when going to the car, prevent to be provided the ration foundation by "bumping porcelain" at crossing etc..
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
