Description
Technical field
The present invention relates to a kind of unmanned automobile-used camera mounting bracket more particularly to a kind of automatic driving car look around it is adjustable
The lockable camera adjustable support of angle.
Background technique
The outer parameter of the camera calibration of unmanned vehicle needs to adjust the field-of-view angle of camera, guarantees that the visual field of camera can see institute
Some scaling boards, calibration need to rigidly fix in camera after terminating, and camera has occurred after offset will lead to once position
Continuous image procossing goes wrong.Camera due on the outside of vehicle body, it is daily it is inevitable scratch, so needing a kind of angle adjustable can
Locked camera support can carry out angular adjustment when calibration, adjust and arrive suitable angle, to complete to demarcate, complete
It is locked by screw means after calibration, to guarantee stability.
Summary of the invention
The purpose of the present invention is to provide a kind of vehicle, especially automatic driving car to look around camera angle adjustable lockable
Camera support can carry out angular adjustment when calibration, adjust and arrive suitable angle, to complete to demarcate, complete calibration
It is locked by screw means afterwards.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of automatic driving car looks around the lockable camera support of camera angle adjustable, by fixing seat, movable support, looks around phase
Machine composition;Fixing seat main body is a right angle frame, and having on one side for right angle frame is multiple for installing the mounting hole of screw, right angle frame
The corner location of frame has reinforcing rib, and the other of right angle frame has a through-hole for cooperating with movable support perpendicular to plane on one side
With an annular through-hole centered on through-hole;It is the rectangle other end is semicircular that the main body of movable support, which is an one end,
Shape component has a hole in the center location of semi-circular ends, in one end of rectangle, with semicircle in one end of semi-circular ends
The hole of one end is the center of circle, there is a ring shaped movable hole, there is rectangle cutting slot at the top of rectangle one end, the width of cutting groove with look around
The thickness of the rotating hole of camera is corresponding, is equipped with the through-hole of a horizontal direction in the centre bit of rectangle cutting slot, tight for installing
The assembly of camera is realized and looked around to firmware;Looking around camera includes a rotating hole and a camera;Fixing seat passes through screw and peace
The cooperation in dress hole realizes that the installation on automobile is fixed;It is connected and fixed the through-hole of seat and the hole of movable support by fastener, leads to
Realize the assembly of fixing seat and movable support in the ring shaped movable hole for crossing annular through-hole and movable support that fastener is connected and fixed seat;
The through-hole connected in the rectangle cutting slot of movable support by fastener realizes movable support and ring with the rotating hole for looking around camera
Depending on the assembly of camera.
Above-mentioned fastener can be the cooperation of threaded rod and nut.
Above-mentioned fastener is connected and fixed the through-hole of seat and the hole of movable support, and movable support can be with fixing seat after connection
Centered on through-hole, it is pivoted.
Above-mentioned fastener is connected and fixed the annular through-hole of seat and the ring shaped movable hole of movable support, when fastener is tightened,
Movable support and fixing seat Complete Bind, movable support are fixed in fixing seat, and when fastener unclamps, movable support can be with
Centered on the through-hole of fixing seat, it is pivoted.
After above-mentioned fastener connects the through-hole in the rectangle cutting slot of movable support and looks around the rotating hole of camera, fastening
When part is tightened, movable support and camera Complete Bind is looked around, look around camera and be fixed on movable support, unclamped in fastener
When, looking around camera can be pivoted centered on the through-hole in the rectangle cutting slot on movable support.
Another aspect of the present invention provides a kind of camera angle method of adjustment of camera support, comprising: in control processing
The heart sends control information to the regulating device by CAN bus, and the regulating device is adjusted according to the control information and installed
The visual field of image collecting device thereon;The wherein reference angle of the control processing center storage described image acquisition device
Degree;
The angular transducer determines the real-time angular of described image acquisition device, and the real-time angular is sent to institute
State control processing center;
The real-time angular is compared by the control processing center with the references angle of storage;When described real-time
When angle and the references angle have angular deviation, the control processing center determines target angle difference and target stepping
Value, and send the drive control information to the stepper motor, wherein the target angle difference be the real-time angular with
Difference between the references angle, the drive control information include the target step value;
The stepper motor adjusts the pitch angle of described image acquisition device according to the target step value.
Preferably, the target angle difference and the target step value are stored for establishing machine learning model.
