Abstract
A vehicle service system including a set of cameras and a processing system configured to access a database of vehicle-specific information, which includes data identifying vehicle-specific targets and/or service fixtures. The processing system is configured with a user interface to convey instructions to an operator, including the identification of vehicle-specific targets and/or service fixtures required to carry out a selected vehicle service. The processing system subsequently evaluates images acquired from the set of cameras to identify features present within the images, including placed vehicle-specific targets, from which identification of, and verification of correctly selected, vehicle-specific targets is made.
Claims15
A vehicle service system including at least one camera disposed to view objects within a vehicle service area, a set of available vehicle-specific targets and/or fixtures configured for observation by vehicle onboard ADAS sensors, and a processing system configured with a user interface and operatively coupled to said at least one camera, comprising:
- wherein said processing system is configured with software instructions to access a database of vehicle-specific information to select a vehicle-specific target and/or fixture for placement within a vehicle service area in response to an identification of a vehicle undergoing an ADAS sensor service procedure;
- wherein said processing system is configured with software instructions to direct an operator to place said selected vehicle-specific target and/or fixture within said vehicle service area;
- wherein said at least one camera is configured to acquire an image of at least a portion of said vehicle-specific target and/or fixture placed within said vehicle service area;
- wherein said processing system is configured with software instructions to evaluate said acquired image to detect data identifying which vehicle-specific target and/or fixture is visible with said acquired image;
- and
- wherein said processing system is further configured with software instructions to compare said identified vehicle-specific target and/or fixture with said selected vehicle-specific target and/or fixture to verify an operator's selection of said vehicle-spacific target or fixture from said set.
A method for verifying an operator's selection of a vehicle-specific target or fixture from a set of available vehicle-specific targets or fixtures during a vehicle onboard ADAS sensor inspection or calibration procedure requiring placement of a vehicle-specific target or fixture relative to a vehicle within a service bay, comprising:
- accessing a data store to recall data identifying a selected vehicle-specific target or fixture from a set of targets and/or fixtures, required for use during said vehicle onboard ADAS sensor inspection or calibration procedure;
- directing positioning of said identified vehicle-specific target or fixture within said vehicle service bay;
- acquiring an image of at least a portion of said positioned vehicle-specific target or fixture within said vehicle service bay;
- evaluating, with a processing system, said acquired image to extract data identifying said positioned vehicle-specific target or fixture within said acquired image;
- and
- comparing an identity of said positioned vehicle-specific target or fixture with said selected vehicle-specific target or fixture to verify said positioned vehicle-specific target or fixtures matches said selected vehicle-specific target or fixture.
A method for detecting an incorrect selection of a vehicle-specific target and/or fixture by an operator from a set of available vehicle-specific targets and/or fixtures during a vehicle onboard ADAS sensor inspection or calibration procedure requiring placement of a vehicle-specific target and/or fixture relative to a known vehicle within a service bay, comprising:
- retrieving, from an accessible data store, data identifying a required vehicle-specific target and/or fixture for use during said vehicle onboard ADAS sensor inspection or calibration procedure associated with said known vehicle;
- identifying said required vehicle-specific target and/or fixture to said operator to enable placement of a selected vehicle-specific target and/or fixture by said operator relative to said known vehicle within said service bay;
- obtaining data identifying said selected vehicle-specific target and/or fixture following said placement within said service bay by said operator;
- and
- comparing said obtained data with said retrieved data to generate a warning to said operator responsive to a mismatch between said obtained data and said retrieved data.
