Abstract
The utility model is related to a kind of laser range sensor accuracy measuring device, the testing field of laser range sensor.It includes a L-type track steel plate, and the L-type track steel plate is placed on horizontal table, and the medial shaft that gauge block is close to L-type track steel plate is faced directly, and laser range sensor is close to gauge block opposite side.L-type track steel plate of the present utility model is that a kind of being postponed to sensor fuselage amount carries out the auxiliary material of correspondence processing, and sensor can be allowed to occur without skew, the interference outside reduction in being preferably fixed on track；The utility model simple structure, it is easy to use.
Description
Technical field
The utility model is related to a kind of laser range sensor accuracy measuring device, the test neck of laser range sensor
Domain.
Background technology
Laser range sensor be it is a kind of using transmission time come the device of measurement distance, general principle is optical triangulation
Method, semiconductor laser focuses on testee by eyeglass.Reflected light is collected by eyeglass, is projected on CMOS array；At signal
Reason device obtains the distance away from object by the light spot position on trigonometric function computing array.
Automobile collision preventing detector：In general, the laser range sensor of most of existing car crass prevention systems makes
It is used to recognize that automobile, in distance preceding or between the object vehicle of rear situation, works as automobile with the not way of contact with laser beam
When being smaller than predetermined safe distance, car collision avoidance System carries out emergency brake to automobile, or alarm is sent to driver, or
Person's integration objective car speed, spacing, automobile brake distance, response time etc. carry out instant judgement and sound to running car
Should, can be with substantial amounts of reduction driving accident.Use on a highway, its advantage is more obvious.
The illegal monitoring of traffic：Because the light beam of laser range sensor is not substantial obstacle, laser is being utilized
When distance measuring sensor road pavement is monitored, the normal operation that can't be blocked the traffic.Therefore, stop or prohibit in some taboos
Only the current section of Pedestrians and vehicles, is fixed with certain altitude with the parallel road surface of laser beam and launches or carry out at a certain angle
Scanning, has vehicle illegal to stop to make a dash across the red light or the illegal leap guardrail of pedestrian etc. when running into, and laser ranging distance value changes, can be with
Alarmed or warned.This application light beam is unnecessary too wide, but general requirement range finding is apart from long, to ensure certain road
The protection distance of segment length.The illegal monitoring system of intelligent transportation that this mode is constituted will obtain very big in traffic Internet of Things
Using.
Traditional laser range sensor accuracy test, be on the metope got in laser, to metope fixed standard gauge block,
The method needs two people to cooperate with could be completed, and when standard gauge block is fixed to metope, difficulty operation is larger, and
It is also possible to gap occurs after fixing.
The content of the invention
The purpose of this utility model is to provide a kind of laser range sensor accuracy measuring device, and the utility model will be solved
Technical problem certainly is that：（1）The simple test of laser range sensor precision is realized, is occurred without it is difficult to control need to measure right
If as, easily be subject to external influence, cumbersome and poor reliability, change laser range sensor measure when, occur it is sharp
The infrared ray that light is difficult to project is difficult to be mapped to measurand, needs when can just be tested and tested after constantly being adjusted
Needing two people to cooperate jointly can just complete the problem of accuracy test.
The utility model to achieve these goals, is adopted the following technical scheme that：
A kind of laser range sensor accuracy measuring device, it includes a L-type track steel plate, and the L-type track steel plate is put
Put on horizontal table, the medial shaft that gauge block is close to L-type track steel plate is faced directly, and it is another that laser range sensor is close to gauge block
Side.
Laser range sensor is a kind of target spacing device, after having the laser diode alignment target in sensor hardware
Transmitting laser pulse, laser is scattered to all directions after being reflected through target, some scattered light is had after scattering returns to sensor and connect
Device is received, is imaged onto on avalanche photodide after being received by optical system.Avalanche photodide is internal with enlarging function
Optical pickocff, therefore it can detect extremely faint optical signal.Record and process to be issued to return from light pulse and received
The time experienced, you can determine target range.
The beneficial effects of the utility model：
L-type track steel plate of the present utility model is that a kind of being postponed to sensor fuselage amount carries out the auxiliary material of correspondence processing
Material, can allow sensor to occur without skew, the interference outside reduction in being preferably fixed on track；The utility model simple structure,
It is easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
1 pair of the utility model is described in detail below in conjunction with the accompanying drawings：
A kind of laser range sensor accuracy measuring device, it includes a L-type track steel plate 1, the L-type track steel plate 1
Place on horizontal table, the medial shaft that gauge block 2 is close to L-type track steel plate 1 is faced directly, and laser range sensor 3 is close to gauge block 2
Opposite side.
Laser range sensor is a kind of target spacing device, after having the laser diode alignment target in sensor hardware
Transmitting laser pulse, laser is scattered to all directions after being reflected through target, some scattered light is had after scattering returns to sensor and connect
Device is received, is imaged onto on avalanche photodide after being received by optical system.Avalanche photodide is internal with enlarging function
Optical pickocff, therefore it can detect extremely faint optical signal.Record and process to be issued to return from light pulse and received
The time experienced, you can determine target range.
