Abstract

The invention provides a laser radar housing. The laser radar housing is in the shape of a barrel. On a cross section comprising a central axis of the laser radar housing, an outer bus and an inner bus of the laser radar housing are arcs bending in the same direction; and at the bottom end and the top end of the housing, the thicknesses of the housing are different. The laser radar housing has the advantages of easy processing and small influence on laser radar and the like.

Description

Laser radar outer housing
Technical field
The present invention relates to photoanalysiss, more particularly to laser radar outer housing.
Background technology
Laser radar is a kind of conventional distance measuring sensor, due to disturbing little etc. excellent with high resolution, by environmental factorss Point, which is widely used in fields such as industrial circle, intelligent robot, automobiles.
At present, laser radar outer housing is mostly cylindrical cover, and such as in patent US8767190B2, HDL-32E laser radars is outer Cover.
In traditional cylindricality cover horizontal direction, due to outer shroud radius of curvature be more than internal ring radius of curvature, optically equivalent to Concavees lens, after detection light is reflected by barrier, when being back to detector through laser radar outer housing, outer housing has diverging to light Effect.In vertical direction equivalent to a plate glass, light is neither assembled nor dissipated.
Therefore there is astigmatism in traditional cylindrical cover, makes image patch become big, reduces detector 15% or so in laser radar Receiving efficiency.
The content of the invention
To solve the deficiency in above-mentioned prior art, the invention provides a kind of laser radar outer housing, it is right to reduce The impact that laser radar detection device is received, improves the receiving efficiency of detector.
The purpose of the present invention is achieved through the following technical solutions:
A kind of laser radar outer housing, the laser radar outer housing are cylindrical in shape;
Comprising the laser radar outer housing central axis section on, the outer side bus of the laser radar outer housing and Interior side bus are the camber line to equidirectional bending, and in the bottom of outer housing and top end, the thickness of the outer housing is different.
According to above-mentioned laser radar outer housing, alternatively, the outer side bus and interior side bus are and bend from inside to outside, Radius of curvature of the radius of curvature of the outer side bus more than interior side bus;Thickness of the thickness on the top of the outer housing less than bottom Degree.
According to above-mentioned laser radar outer housing, alternatively, top plan and the curvature half of the laser radar outer housing Distance between the datum line of footpath is more than zero, and the radius of curvature datum line is non-intersect with outer housing.
According to above-mentioned laser radar outer housing, alternatively, the outer side bus and interior side bus are and bend from the outside to the core, Radius of curvature of the radius of curvature of the interior side bus more than outer side bus;Thickness of the thickness on the top of the outer housing more than bottom Degree.
According to above-mentioned laser radar outer housing, alternatively, bottom plane and the curvature half of the laser radar outer housing Distance between the datum line of footpath is more than zero, and the radius of curvature datum line is non-intersect with outer housing.
Compared with prior art, the device have the advantages that being:
By preferred outer side bus and the radius of curvature of interior side bus so that disperse function vertically and horizontally Quite so that detector receiving efficiency reduces the adverse effect received to detector more than 97%, to greatest extent.
