## Abstract

An autonomous and non-autonomous vehicle tire imaging and inspection system and methods thereof installed onboard a vehicle providing frequent status for inner and outer tire sidewalls, tire tread wear and tread depth, recorded in memory, transmitted to an onboard diagnostics unit, displayed on a dashboard and optionally transmitted to a network. Autonomous and non-autonomous vehicle vehicles may require passing a safety compliance inspection before driving and receive an insurance compliance approval to operate said vehicles.

## Claims

### Claim 1

An apparatus, comprising:
an integration of a stereoscopic imaging unit and an image processing and hardware control unit (SIU & IPHWCU) for a self-contained unit mounted on a vehicle, configured to couple visually with a vehicle tire and operative to capture at least one three-dimensional tire tread image pair;
an image processing code operative to process the at least one three-dimensional tire tread image pair for a tire inspection and a detection of tire condition defects;
a program instruction code operative to run the image processing and hardware control unit and host the image processing code, wherein the program instruction code provides hardware circuit interfaces drivers to communicate with the stereoscopic imaging unit and other interface circuits; and
a code configured to execute a service request upon the detection of tire condition defects, wherein the service request triggers a vehicle tire maintenance operation;
wherein at least one SIU & IPHWCU is operative to couple over a physical transmission media with at least one on board diagnostics (OBD) unit;
wherein the SIU and IPHWCU is operative to couple over the physical transmission media couple to a vehicle control unit; and
wherein the vehicle control unit comprises: steering control units, generic vehicle computer units, and transmission control units;
wherein the vehicle control unit can act as a master controller for the vehicle and the SIU & IPHWCU can act as a peripheral device.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the physical transmission media comprises HDBaseT signaling.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein the image processing code executes on a non-real-time image processor for leveraging a minimum amount of processing power to analyze stereo image pairs for high volume production efficiency and lower manufacturing costs.

### Claim 4 (depends on 2)

The apparatus according to claim 2, wherein the physical transmission media further couples to a 5G radio frequency (RF) communications unit, wherein the 5G radio frequency (RF) communications unit is operative to communicate with an external network.

### Claim 5 (depends on 1)

The apparatus according to claim 1, further comprising an optics lens cover to protect optics in the stereoscopic imaging unit from dirt, grease, grime, and filth, wherein a movable mechanism closes the optics lens cover by default and opens the optics lens cover to expose the optics during an image capture.

### Claim 6

A method of imaging and inspection of a vehicle tire comprising:
capturing at least one three-dimensional image pair of the vehicle tire by a stereoscopic imaging unit and operative to transfer the at least one three-dimensional image pair to at least one image processor and hardware control unit (IPHWCU);
processing at least one three-dimensional image pair of the vehicle tire in at least one IPHWCU utilizing image processing software for inspecting tires;
detecting a tire condition defect in the at least one three-dimensional image pair of the vehicle tire;
and triggering a service request for a tire maintenance service;
wherein a vehicle ownership is selected from a group consisting of: a federal agency, state, county, local government, private ownership, and corporate entity;
wherein a vehicle is a non-autonomous vehicle, or the vehicle is an autonomous self-driving vehicle;
wherein triggering the service request for the tire maintenance service is saved in an optional onboard diagnostics (OBD), where an OBD configuration receives data from one or more IPHWCU for generation of one or more diagnostic codes associated with one or more vehicle tire inspections and the OBD is operative for storing tire inspection results in a non-volatile memory;
wherein the OBD may log compliance verification to the non-volatile memory for servicing and insurance policy compliance.

### Claim 7

A tire inspection apparatus mounted onboard a vehicle operating, comprising:
a stereoscopic imaging unit (SIU) and an image processing and hardware control unit (IPHWCU) mounted on a vehicle with a mounting hardware, the SIU configured to couple visually with a vehicle tire for monitoring a tire status and operative to capture at least one three-dimensional tire tread image pair and capture at least one three-dimensional tire inner sidewall image pair and at least one three-dimensional tire outer sidewall image pair; and

wherein the mounting hardware further comprises a stepper motor or a direct-current motor to enable mechanical movements for positioning and aiming of image sensors; and
wherein the mechanical movements comprise an element selected from a group comprising: (1) an epicyclic train allowing for adjusting an angular image capture of the tire tread, inner tire sidewall, and outer tire sidewall or sidewall; (2) a rectilinear slide motion, whereby a screw guides the image sensors to a more favorable FOV position; and

wherein the SIU includes a plurality of two or more image sensors.

### Claim 8 (depends on 7)

The tire inspection apparatus according to claim 7, further comprising an image processing code for image recognition of the text for tire codes to access manufacture recalls listed in online databases and image recognition of date tire codes for expiration dates to trigger warnings to replace tires.

### Claim 9 (depends on 7)

The tire inspection apparatus according to claim 7, further comprising a data storage comprising:
an insurance information data repository to store information corresponding to one or more vehicle insurance policies comprising a policy identifier; a name of one or more insured parties associated with a vehicle; an address associated with the one or more insured parties; one or more vehicle identifiers associated with one or more insured individuals; preferences information; a personal insurance policy or a commercial insurance policy; and
a tire defect diagnostic code data repository.

### Claim 10 (depends on 7)

The tire inspection apparatus of claim 7, wherein monitoring is a real-time monitoring.
