Ok, I had a chance finally to review the GM patent fully and JC's favourite SEE patent - SYSTEM AND METHOD FOR IDENTIFYING A CAMERA POSE OF A FORWARD FACING CAMERA IN A VEHICLE.
I jumped the gun a bit when I saw reference to the camera moving to improve visibility, and guessed that it could be the visor or rear view mirror, but it was just the steering wheel/column that was moving along with the driverchair.
It just goes to show how powerful our IP is in this area. John Noble, Tim Edwards, Sebastian Rougeaux, James Henry, Grant Grubb and others have done a great job and I hope they have plenty of shares so that they can profit from their incredible work.
Very interesting chaps, rear view mirror, again a link to CMD and the Colin Barnden presenetation
That's the one JC.
These are published in multiple countries with different references but I eventually found the matching number that was mentioned in the rejection of some of GM's claims.
When I get some time I will sit down on a proper screen and review them both. But it looks like GMs reason for the patent was the sunlight problem in the CT6. So they were looking to move to a movable part of the car (sun visor/rear view mirror?) that would need more calibration
Replacement
Correct me if I'm wrong TLS but I think your referring to SEE patent ;

Ok so John Noble is the super intelligent chap I spoke to at CMD, very very impressive.
TLS or JC (speaking of super intelligent) does this mean that we have a clear link from the GM patent to SM ?
This idea sound familiar, so I checked the Dossier:
"Claims 1, 4-5, 11, is/are rejected under 35 U. S. C. 102(a)(1) as being anticipated by Nobel et al (US201902064084)"
That name sounds familiar! JC will no doubt have a link.
MOVEMENT TRACKING OF OPERATOR-FACING CAMERAS
Systems and methods for optimizing operator-state detection including tracking position of an operator-facing camera are described. Systems and methods include receiving a first image captured by an operator-facing camera, detecting a first position of the operator-facing camera with respect to the calibration object, ascertaining the first position with respect to at least one fiducial marker within a passenger compartment of a vehicle, capturing, via controller, a second image using the operator-facing camera, determining the second image is captured by the operator-facing camera from a second position with respect to the at least one fiducial marker, and analyzing, based on determining the second image is captured by the operator-facing camera from the second position, the second image to identify facial features of the operator. The receiving, detecting, ascertaining, determining, and analyzing are performed via a controller. The first image includes a calibration object disposed at a predetermined location.
Beneficially, systems and methods in accordance with the present disclosure may optimize functioning of an operator monitoring system. Such optimizations may include optimizing the identification of facial features, reducing processing time required to identify facial features, reducing data storage requirements for analysis of facial features, and/or reducing misidentification of an operator's state. Further, systems and methods in accordance with the present disclosure may optimize vehicle function through accurate assessment of an operator state. Such optimized vehicle function may include prolonged operation in autonomous and semi-autonomous modes to thereby reduce operator interventions with the vehicle and reduced handoffs between autonomous and non-autonomous modes. According to aspects of the present disclosure, these and other benefits are accomplished by systems and methods of tracking spatial placement of an operator-facing camera that is movable, for example, during adjustments to optimize visibility and comfort of an operator.
Claims
1. A method comprising:
receiving, via a controller, a first image captured by an operator-facing camera, the first image including a calibration object disposed at a predetermined location, the operator-facing camera being movable within a passenger compartment of a vehicle;
