Abstract
The subject disclosure relates to techniques for positioning an autonomous vehicle for sensor calibration. A process of the disclosed technology can include steps for positioning an autonomous vehicle along a first axis on a platform in a predetermined environment using guide rails, positioning the autonomous vehicle along a second axis on the platform using one or more elevated platform features, inserting one or more lifting alignment pins of a lifting mechanism into one or more sockets located on an underbody of the autonomous vehicle, and positioning the autonomous vehicle along a third axis using the lifting mechanism. Systems and machine-readable media are also provided.
Claims20
A method comprising:
- positioning an autonomous vehicle along a first axis on a platform in a predetermined environment using guide rails;
- positioning the autonomous vehicle along a second axis on the platform using one or more elevated platform features, wherein the second axis is orthogonal to the first axis;
- inserting one or more lifting alignment pins of a lifting mechanism into one or more sockets located on an underbody of the autonomous vehicle;
- and
- positioning the autonomous vehicle along a third axis using the lifting mechanism, the third axis orthogonal to the first axis and the second axis.
A system comprising:
- a predetermined environment having a platform;
- the platform comprising one or more guide rails, wherein the guide rails are configured to facilitate positioning of an autonomous vehicle along a first axis of the platform;
- one or more elevated platform features disposed on a surface of the platform, wherein the one or more elevated platform features are configured to facilitate positioning of the autonomous vehicle along a second axis on the platform, wherein the first axis is orthogonal to the first axis;
- a lifting mechanism coupled to the platform, wherein the lifting mechanism is configured to facilitate positioning of the autonomous vehicle along a third axis respective to the platform, wherein the third axis is orthogonal to the first axis and the second axis;
- and
- one or more lifting alignment pins coupled to the lifting mechanism, the one or more lifting alignment pins configured to insert into one or more sockets located on an underbody of the autonomous vehicle.
A non-transitory computer-readable medium comprising instructions thereon, the instructions effective to cause one or more processors to:
- position an autonomous vehicle along a first axis on a platform in a predetermined environment using guide rails;
- position the autonomous vehicle along a second axis on the platform using one or more elevated platform features, wherein the second axis is orthogonal to the first axis;
- insert one or more lifting alignment pins of a lifting mechanism into one or more sockets located on an underbody of the autonomous vehicle;
- and
- position the autonomous vehicle along a third axis using the lifting mechanism, the third axis orthogonal to the first axis and the second axis.
