The present apparatus utilizes machine vision range measurement principle, passes through the laser and area array cameras pair below locomotive car body
The relative distance of locomotive and track measures, and the different distance data arrived according to locomotive car body both sides camera calibration, utilizes
Triangle polyester fibre principle calculate locomotive center line and rail plane angle and underbody both ends to rail plane range difference, so as to push away
Offset data when locomotive sidewinders skew is calculated, finally obtained offset data is added in the dynamic detection result of bow net,
Solve for a long time because body oscillating causes the not high problem of dynamic detection data precision, further increase dynamic detection
Precision.And laser and area array cameras are assembled into a module by the present apparatus, structural volume is small, can be direct by mounting bracket
Easy for installation on underbody crossbeam, potential safety hazard is small.
As preferred scheme of the present utility model, it is big that each described device body by mounting bracket is fixed on the underbody
Liang Shang, it is easy for installation.
As preferred scheme of the present utility model, each mounting bracket is welded on the underbody crossbeam.
As preferred scheme of the present utility model, each described device body is screwed in the mounting bracket
On.
As preferred scheme of the present utility model, two described device bodies relative to the locomotive the symmetrical cloth of center line
Put, the vibration compensation result precision calculated is higher.

Shell.
As preferred scheme of the present utility model, aviation plug is additionally provided with the shell.
As preferred scheme of the present utility model, the aviation plug is waterproof aviation plug.
As preferred scheme of the present utility model, the area array cameras is high frame per second area array cameras.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
(1) present apparatus utilizes machine vision range measurement principle, passes through the laser below locomotive car body and face battle array phase
The relative distance of machine-to-machine car and track measures, and the different distance data arrived according to locomotive car body both sides camera calibration,
Using triangle polyester fibre principle calculate locomotive center line and rail plane angle and underbody both ends to rail plane range difference, from
And offset data when locomotive sidewinders skew is extrapolated, obtained offset data is finally added to the dynamic detection result of bow net
In, solve for a long time because body oscillating causes the not high problem of dynamic detection data precision, further increase dynamic
The precision of detection.
(2) laser and area array cameras are assembled into a module by the present apparatus, and structural volume is small, can be straight by mounting bracket
Connect on underbody crossbeam, easy for installation, potential safety hazard is small.
