Abstract
The utility model discloses an equidistance speed measurement photographing device which is characterized by: arranging a wide angle camera being perpendicular to the floor in a position above the floor with a certain height; setting the time for pavement distance through the wide angle camera in the course of driving for vehicles; and calculating for obtaining the driving speed for vehicles. The equidistance speed measurement photographing device provided by the utility model has the advantages that: simply one wide angle camera can realize speed measurement function and image record function at the same time so that not only the construction cost is significantly saved, but also the speed measurement point can stop speed measurement for vehicles immediately when the wide angle camera goes wrong, thus avoiding erroneous judgment to decrease traffic disputes.
Description
Technical field
The utility model relates to the velocity measuring technique field, particularly a kind of device that utilizes video camera that driving vehicle is tested the speed and takes pictures.
Background technology
High speed development along with highway and automotive engineering; The traffic administration of road is also more and more skillful, and particularly along with development of science and technology, the application of electronic communication management more and more receives people's attention; Whether this technology can be monitored the vehicle that goes in real time, exceed the speed limit to judge vehicle.And requirement must be driven over the speed limit to motor vehicles and carried out dynamic image and retain in the new traffic law, with as the evidence of enforcing the law.Yet existing speed measuring device adopts the induction detecting element to combine some video cameras to realize jointly mostly, as utilizes radar Doppler wave reflection, infrared induction, ground buried coil etc., can carry out work through together setting up just with video camera.The radar Doppler wave reflection is tested the speed and is adopted the microwave device launched microwave, utilizes its reflection to carry out velocity determination.As everyone knows, long-term low dose of microwave has stronger injury effect to human body equally, is unfavorable for building the social development environment of harmony, environment-friendly type so the public arena is supposed the microwave transmitter on a large scale.The infrared induction method need accurately be installed infrared transmitter in the place beyond video camera, and higher to installing and using environmental requirement, investment is also bigger simultaneously.Ground buried coil need cut out the laying installation that coil is carried out in large-area slit on the road surface of accomplishing of constructing; The damaged condition of road pavement is serious; Cold and hot along with the road surface simultaneously, sedimentation changes; Ground buried coil can receive very big cutting force and damage, and this coil method can not reuse, and causes the waste of material and the pollution of environment.No matter therefore adopt which kind of sensing element, all can increase the whole cost of equipment, strengthen the difficulty of maintaining.
The utility model content
The technical matters that the utility model solves provides a kind ofly can carry out short distance to vehicle and test the speed in real time, do not have that the erroneous judgement phenomenon takes place, and the equidistance that can the reduce construction cost camera arrangement that tests the speed.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
The equidistance camera arrangement that tests the speed; Comprise the support that fixes on the ground and the video camera on the support is set; With the central control system that the wide-angle imaging machine is connected through data line, said video camera is the wide-angle imaging machine, only is provided with a wide-angle imaging machine on the said support.
Owing to adopted above technical scheme, the acquisition of technology progress of the utility model institute is:
The utility model only need be set the height of a wide-angle imaging machine apart from ground exactly; Can realize mensuration to Vehicle Speed; And can arbitrarily be provided with according to the specific requirement of different speed measuring points, also can not produce and destroy, significantly reduced construction cost ground.When the wide-angle imaging machine broke down, this speed measuring point just stopped the measurement to car speed immediately, and the generation of avoiding judging by accident phenomenon has reduced the traffic dispute.The set wide-angle imaging machine of the utility model not only can fix a point to test the speed to dynamic vehicle, can also realize dynamic image retention function; The wide-angle imaging machine also can be stored and analysis and judgement measurement result except having these two functions, has only when speed surpasses setting speed and just can give central control system with information transmission, has alleviated the working load of central control system greatly.
The employed wide-angle imaging machine of the utility model can not produce any electromagnetic radiation when working, and can not work the mischief to the person, is applicable to the construction of environment-friendly type society.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model embodiment 1;
Fig. 2 is the vertical view of the utility model embodiment 2.
Wherein: 1. wide-angle imaging machine, 2. support, 3. vehicle, 4. angular field of view.
Embodiment
To combine specific embodiment and accompanying drawing that the utility model is further elaborated below.
The equidistance camera arrangement that tests the speed is applied on highway or the ordinary road driving vehicle tested the speed and takes pictures.As shown in Figure 1, vertically set up a wide-angle imaging machine 1 in a side of the required speed measuring point of road through support 2.The wide-angle imaging machine according to its angular field of view 4 and the vertical height H overhead that sets up, calculates the measuring distance S of measurement point when setting up.
When vehicle 3 gets into the angular field of view of wide-angle imaging machine certainly, the t1 that picks up counting, when leaving angular field of view, timing ends up being t2, and the mistiming in this segment distance is Δ t=t2-t1, calculates the speed v=S/ Δ t of measurement point vehicle ' at last.When travel speed surpasses setting speed, give central control system with information transmission, carry out penalty and handle.
The wide-angle imaging machine carries out image to dynamic vehicle and retains when vehicle is tested the speed.
The difference of present embodiment and embodiment 1 is: the utility model is applied to the crossroad traffick is tested the speed and the image retention, and the position of wide-angle imaging machine is positioned at the center of crossroad, and its angular field of view is radiated whole crossroad.When current vehicle occurred violating the regulations or exceed the speed limit phenomenon, the wide-angle imaging machine was promptly taken pictures to vehicles peccancy, and is transferred to central control system.
Claims (1)
1. the equidistance camera arrangement that tests the speed; Comprise the support that fixes on the ground and the video camera on the support (2) is set; The central control system that is connected through data line with the wide-angle imaging machine; It is characterized in that: said video camera is wide-angle imaging machine (1), only is provided with a wide-angle imaging machine on the said support.
