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.
