Abstract
The utility model relates to a laser radar technical field discloses a panorama laser rangefinder radar, including area array CCD, toper speculum and linear laser instrument, the round laser beam can be caught to linear laser instrument to get to on the barrier that awaits measuring, the barrier reflects through awaiting measuring on the toper speculum, the reecho forms the barrier image to the area array CCD, according to the awaited measuring distance of barrier of barrier image. The utility model discloses can simplify laser radar's structure to improve its reliability and stability, also enlarged laser radar's range finding angle scope simultaneously.
Description
Technical field
The utility model relates to laser radar technique field, in particular, and particularly a kind of panorama range laser radar.
Background technology
Rapidly, small low-cost laser radar especially prospect is extensive in laser radar technique development in recent years.Existing laser radar many employings driven by motor range cells carries out 360 degree of comprehensive scannings, and this structure requires higher to motor and gear train, and traditional power supply and data transmission adopt electronics slip ring, the requirement worked when can not meet farm labourer.
Summary of the invention
The purpose of this utility model is the technical matters existed for prior art, provides a kind of panorama range laser radar, can simplify the structure of laser radar, and improve its reliability and stability, have also been enlarged the range finding angular range of laser radar simultaneously.
In order to solve problem set forth above, the technical solution adopted in the utility model is:
A kind of panorama range laser radar, comprises area array CCD, taper reflection and linear laser; Described linear laser can get a circle laser beam, and gets on barrier to be measured; Reflexed on described taper reflection by barrier to be measured, then reflex on area array CCD and form obstructions chart picture, obtain the distance of barrier to be measured according to described obstructions chart picture.
Adopt three described linear laser fixing in one plane, be namely arranged on laser instrument holder, three linear laser angle is between any two 120 °.
Described taper reflection is positioned at immediately below area array CCD, and its taper surface is corresponding with the position of area array CCD, and both are positioned at directly over three described linear laser.
Described area array CCD can adopt cmos sensor to replace.
Compared with prior art, the beneficial effects of the utility model are:
Fixed planar array type panorama laser radar is adopted in the utility model, the mechanical drive of laser radar during rotation, electrical machinery life, vibrations etc. series of problems can be eliminated, the more important thing is and solve Signal transmissions and powerup issue, simplify the structure of laser radar, thus improve the reliability and stability of radar; In addition, coordinated by full shot and CCD and taper reflection, the range finding angular range of laser radar can be expanded, improve the performance of laser radar.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model panorama range laser radar.
Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in instructions of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Consult shown in Fig. 1, a kind of panorama range laser radar that the utility model provides, comprise area array CCD 1, taper reflection 2 and linear laser 4, described linear laser 4 can get a circle laser beam, and gets on barrier 5 to be measured; Reflexed on described taper reflection 2 by barrier 5 to be measured, then reflex on area array CCD 1 and form obstructions chart picture, obtain the distance of barrier 5 to be measured according to described obstructions chart picture.
In above-mentioned, three described linear laser 4 are fixing in one plane, in order to install and convenient fixing, are namely arranged on laser instrument holder 3, three linear laser 4, between any two in 120 ° of distributions, are convenient to the laser beam that three linear laser 4 can get a circle like this.
In above-mentioned, a full shot is installed above linear laser 4, described full shot comprises an area array CCD 1 and a taper reflection 2, described taper reflection 2 is positioned at immediately below area array CCD 1, its taper surface is corresponding with the position of area array CCD 1, and both are positioned at directly over three described linear laser 4.
What get due to three linear laser 4 is a circle laser beam, after being acted on by taper reflection 2, the obstructions chart picture that area array CCD 1 obtains is exactly the image and panoramic picture that within the scope of the whole week 360 °, all laser spots reflect, digital processing is carried out by range of triangle algorithm again according to panoramic picture, the range information around barrier 5 to be measured can be obtained, namely expand the finding range of laser radar.
In above-mentioned, described area array CCD 1 can adopt cmos sensor to replace.
In above-mentioned, according to a linear laser 4, by driven by motor, it rotates, and is also planar to get a circle laser beam.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
