“GPS is nice in locations, however we go to locations like Monaco, Baku, Singapore, the place all that infrastructure and buildings actually make GPS drift,” says Dean Locke, director of broadcast media and digital for Method 1.
F1 vehicles are additionally a lot lighter than their Nascar counterparts, necessitating lower-weight sensors. Its broadcast groups struggled to place collectively full laps of ghost automotive or associated overlay options in consequence.
To get round these limitations, F1 constructed a number of inner prediction fashions primarily based on previous seasons’ GPS information and lidar scans of every observe. It then built-in these fashions into an in-house software that overlayed a synchronized video feed of those self same previous qualifying trials, then in contrast the 2 information inputs aspect by aspect. By first manually figuring out discrepancies the place GPS information from qualifying clearly was out of whack primarily based on video footage, the crew was capable of practice its fashions to identify anomalies and proper them.
F1’s personal ghost automotive characteristic launched throughout its broadcasters for the 2025 season. It options each an in-car driver view and a “helicopter” view above the automotive—particularly useful for qualifying laps the place the present driver is forward of the ghost automotive, because the ghost automotive can be invisible throughout in-car views in these conditions.
A disadvantage, although: F1 can’t but present its ghost automotive on stay broadcasts. As a result of the crew’s course of nonetheless requires that ultimate little bit of guide fine-tuning to make sure the translucent ghost automotive is positioned accuracy, Locke says it takes round 90 minutes to cross the ghost automotive overlay to broadcast companions after every qualifying run. The crew’s objective is a 30-minute turnaround to facilitate faster post-qualifying evaluation. Nonetheless, Locke says, ghost automotive broadcasts have been immensely common on F1’s social channels.
F1’s single-car opponents at IndyCar, in the meantime, have pushed the envelope additional this season as Fox, the house of Nascar, has taken over from NBC because the IndyCar collection’ broadcaster, bringing SMT’s vector field expertise with it. Beginning with Indy 500 qualifying earlier in Could, a completely stay ghost automotive animation has been used as a superimposed overlay for Fox’s in-car driver digital camera. This isn’t a 3D rendering, like SMT’s prior Nascar ghost vehicles, which swap right into a separate digital view (both the complete display or smaller field format); it’s the precise, real-life driver digital camera from the printed with a centimeter-accurate ghost automotive overlayed onto the display.
Laps of Judgment
Ghost vehicles are nonetheless of their relative infancy, particularly for really stay broadcasts. Corridor sees the makes use of of this underlying expertise shortly increasing as broadcasters turn into extra acquainted with them—together with for full-field races along with qualifiers.
“Perhaps you wish to evaluate tire put on,” Corridor posits. “Let me present you this automotive now operating stay, and let me present you this automotive 5 laps in the past the place it was operating on totally different tires.”
Corridor additionally suggests the thought of a number of ghost vehicles for qualifying; one for the pole sitter, however maybe others for bubble positions or different related spots.
It is easy to see how the ghost vehicles zipping round in your TV may simply be the start of the way in which this ultra-specific automotive information can be used. Simply take a look at Nascar; SMT acquired curiosity from a number of groups inside lower than a yr of pioneering its vector field. The groups wished to make use of information from the field for tactical functions like postrace evaluation or comparisons to opponents, and SMT developed a Group Analytics software.
Demand was so excessive that in 2018, Nascar opened this information as much as enable all groups full entry. They will view every part from automotive positioning to gear and throttle information, not only for their very own drivers however for the entire subject. Group Analytics has a characteristic that enables a number of ghost automotive overlays of prior races, permitting crews to match driving strains or flip speeds.
“Now at each pit stall, it’s the heart software,” Corridor says. “As a result of the groups, the crew chiefs, they wish to know: How is my automotive doing relative to different vehicles? And since it’s not simply positioning on the observe, it’s additionally gears, throttle, et cetera, totally different drivers can evaluate their efficiency in opposition to” one another.
It is probably solely a matter of time earlier than these options trickle into IndyCar and F1 groups.
Locke says these groups “will use completely something they’ll to get an enchancment over one other crew,” although he notes that F1 groups already accumulate a wealth of inner information on their autos.
