The utility model discloses an at two constant spacing's of car afterbody installation infrared emission unit, to vehicle rear transmission infrared signal, after infrared signal is caught to the camera of rear vehicle, through the processing of central processing unit to infrared signal, the range display with the front truck on LCD display element, the distance of reminding car owner and front truck is supported for the safety traffic of car provides powerful.
Description
Technical field
The utility model relates to traffic safety technology field, particularly relates to a kind of based on infrared distance survey system.
Background technology
At present at automotive field, automatic Pilot has become a very popular topic, research basic a bit is all being done for reaching automatic Pilot by a lot of companies, wherein the very important point is exactly measure the spacing with front truck, there is now a variety of method, but wherein most methods is measured is not very accurate, but also is subject to the restriction in the visual field.
Utility model content
The utility model proposes a kind of based on infrared distance survey system, use active infrared monumented point to measure spacing, accurately can measure spacing and not by the restriction in the visual field.
The technical solution of the utility model is achieved in that
A kind of based on infrared distance survey system, comprise the first infrared emission unit, the second infrared emission unit, camera, central processing unit and LCD display unit, described first infrared emission unit and described second infrared emission unit are arranged on automobile tail with constant spacing, launch infrared signal to rear view of vehicle; Described camera is arranged on automotive front, catches the infrared signal that front vehicles afterbody is launched; Described central processing unit accepts and processes the infrared signal that described camera catches, and result is presented at described LCD display unit.
As preferably, described first infrared emission unit and the second infrared emission unit outside are provided with diffuse reflector.
As preferably, described central processing unit is 16 single-chip microcomputers.
As preferably, described central processing unit is 32 single-chip microcomputers.
As preferably, described LCD display unit is film crystal tubular type display screen.
Employing the beneficial effects of the utility model are:
It is a kind of based on infrared distance survey system that the utility model provides, by installing the infrared emission unit of two constant spacings at automobile tail, automobile in the process of moving, the infrared ray that the infrared emission unit of front truck afterbody is launched can be caught by the camera of automotive front, through the process of central processing unit to infrared signal, distance with front truck can be presented on LCD display unit, remind the distance of car owner and front truck, the utility model structure is simple, and the active safety for running car provides strong support.

Embodiment
Below in conjunction with the drawings and specific embodiments, clear, complete explanation is carried out to the utility model.
As shown in Figure 1, the utility model provides a kind of based on infrared distance survey system, comprise the first infrared emission unit 1, second infrared emission unit 2, camera 3, central processing unit 4 and LCD display unit 5, first infrared emission unit 1 and the second infrared emission unit 2 are arranged on automobile tail with fixing spacing, powered by vehicle power, launch infrared signal to rear view of vehicle; Camera 3 is arranged on automotive front, catches the infrared signal that front vehicles afterbody is launched; Central processing unit 4 is arranged on vehicle interior, is powered by vehicle power, and central processing unit 4 accepts and processes the infrared signal that described camera catches, and result is presented at LCD display unit 5.
Further, as shown in Figure 2, the first infrared emission unit 1 and the second infrared emission unit 2 outside are provided with diffuse reflector 6.
Further, central processing unit 4 is 16 single-chip microcomputers or 32 single-chip microcomputers.
Further, LCD display unit 5 is film crystal tubular type display screen.
As in Figure 3-5, the concrete steps of native system measurement spacing are as follows:
1) under static state in advance, the spacing of the first infrared emission unit 1 and the second infrared emission unit 2 is fixed as a rice, the focal length of camera 3 is s, camera 3 is placed on distance first infrared emission unit 1 and the second infrared emission unit 2 is d rice, and now the first infrared emission unit 1 of camera imaging and the second infrared emission unit 2 spacing are b rice; Dollying head 3 backward, makes camera 3 be L rice apart from the first infrared emission unit 1 and the second infrared emission unit 2, is now c rice at the first infrared emission unit 1 of camera 3 imaging and the second infrared emission unit 2 spacing; According to similar triangle theory, draw L/d=b/c, when measurement camera 3 is 1 ~ 1000 meter apart from the first infrared emission unit 1 and the second infrared emission unit 2 respectively in this way, first infrared emission unit 1 and the second infrared emission unit 2 spacing of corresponding camera 3 imaging, forms a number value table of comparisons;
2) the numerical comparatives table that the static data in above-mentioned steps is formed is stored in central processing unit 4;
3) under transport condition, after camera 3 catches the infrared signal of front vehicles afterbody transmitting, central processing unit 4 can according to the first infrared emission unit 1 and the second infrared emission unit 2 spacing of camera imaging, in numerical comparatives table, find corresponding vehicle distance data, be presented on LCD display unit 5.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; the Method and Technology content of above-mentioned announcement can be utilized to make possible variation and amendment to technical solutions of the utility model; therefore; every content not departing from technical solutions of the utility model; the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all belong to the protection domain of technical solutions of the utility model.
