US 10,539,413 B2 · Live ride height measurement

Abstract

Methods and systems measure a vehicle body parameter; e.g., a wheel alignment parameter such as ride height. Embodiments include a system having a target attachable to a vehicle body, and an image sensor for viewing the target and capturing image data thereof. A processor processes the image data, determines an initial spatial position of the target based on the processed image data, compares the initial spatial position of the target with a reference position, and prompts a user to align the target to an adjusted spatial position when the initial spatial position differs from the reference position more than a threshold amount. The vehicle body parameter value is determined based on the target's adjusted spatial position. In certain embodiments, the adjusted spatial position differs from the reference position by a position error value, and the processor mathematically corrects the vehicle body parameter value based on the position error value.

Dependent claims

A method for measuring a parameter of a vehicle body, the method comprising:

attaching an optical target to the vehicle body;
imaging the target with an image sensor to produce image data of the target;
determining an initial spatial position of the target based on the image data of the target;
determining a value for the vehicle body parameter based on the initial spatial position of the target;
comparing the initial spatial position of the target with a predetermined reference position for the target to determine a position error value representing a difference between the initial spatial position and the reference position;
and
mathematically correcting the determination of the value for the body parameter based on the position error value.
