Abstract
A distance sensor and a measured object are positioned at a known distance from each other. A measured distance between the distance sensor and the measured object is obtained from the distance sensor, where the distance sensor uses a plurality of signals at a plurality of angles to generate the measured distance. The known distance and the measured distance are compared in order to test the distance sensor and produce a test result.
Claims7
A system, comprising:
- equipment that is configured to position a distance sensor and a measured object at a known distance from each other, wherein:
- the distance sensor includes one or more of the following:
- a radar based distance sensor or a Lidar based distance sensor;
- the measured object is a ground simulator;
- the ground simulator is coupled to a ball bearing carriage and configured to move via the ball bearing carriage;
- and
- positioning includes:
- inserting at least one peg into at least one of a plurality of holes provided along a longitudinal axis of a guard rail and corresponding to known distances from the measured object, and
- rolling the ball bearing carriage along the guide rail to a position where an edge of the ground simulator comes into contact with the at least one peg;
- and
- a test controller that is configured to:
- obtain, from the distance sensor, a measured distance between the distance sensor and the ground simulator included in the measured object, wherein:
- the distance sensor transmits a plurality of signals at different angles to generate the measured distance;
- and
- the plurality of signals includes one or more of the following:
- a plurality of radar signals or a plurality of Lidar signals;
- and
- compare the known distance and the measured distance in order to test the distance sensor and produce a test result.
