Stereo Dishwashing and Kitchen Sanitation Data

It is first-person video of a person doing commercial kitchen wash-up and clean-down work, recorded from their own point of view with two calibrated cameras and with hand pose and sensor streams alongside. The tasks are the rows the site’s catalog lists in Restaurant & Commercial Kitchen. Stereo describes the capture, and MCAP describes the container. They are separate choices.

The site does not state that stereo is already running on these rows. The catalog lists a head-mounted phone or a multiview rig as the capture setup, and a stereo pair is a capture choice agreed in the skill spec and confirmed on a Spec Pilot. The data is human capture by paid, consented contributors, not robot or teleoperation data. Firsthand is not affiliated with Foxglove or the MCAP maintainers.

Four, all in Restaurant & Commercial Kitchen under Food & Beverage. The catalog lists examples for the environment such as a sit-down restaurant kitchen, a café, a coffee shop, an artisan bakery and a patisserie. "Restaurant Dishwashing" is described as operating dish pits, racking, washing and putting away commercial kitchenware, is rated Easy and is listed as Active collection. "Wash and rack dishware using a commercial dishwasher and spray hose" is described as spraying off plates, racking them, running the dishwasher and putting clean ware back on shelves, is rated Easy and is listed as Active collection.

"Degrease and scrub kitchen surfaces using degreaser and scrub pads" is described as spraying degreaser on hoods, walls and counters, scrubbing with pads and rinsing the surfaces clean, is rated Easy and is listed as Active collection. "Restaurant Kitchen Deep Clean" is described as emptying and scrubbing fryers, hoods, floors and shelving with degreaser, brushes and mops, is rated Medium and is listed as Ready to deploy. All four list a head-mounted phone or a multiview rig as the capture setup. The site says nothing further about what each status means in volume, hours or delivered stereo footage, so this page claims none, and what applies to a given order is confirmed when you request the quote. This page names only the tools and steps that appear in the four rows. The first table below reproduces them as the catalog states them.

The egocentric dishwashing page covers the two dishwashing rows as first-person capture, alongside a home kitchen set. Its only depth note is that wet and reflective surfaces degrade active-stereo depth, and it has no stereo-pair or MCAP treatment. The egocentric food plant sanitation and washdown page covers the two degreasing and deep clean rows together with two food plant rows, and has no stereo or MCAP treatment.

The stereo floor mopping page is stereo and MCAP, but its rows are the mopping, floor-care and janitorial ones, not these kitchen rows. This page is the stereo and MCAP treatment of the four Restaurant & Commercial Kitchen wash and clean-down rows together, and it leaves the food plant rows out. The comparison table below sets the pages side by side.

Wash-up and clean-down work is about where the hands, the ware or tool and the surface sit relative to one another: where a plate goes in a rack, how far a hose is from a counter, where a scrub pad has been on a hood. A stereo pair recovers depth from the calibrated frame pair rather than from a standalone depth sensor, so the ware, the rack, the surface and the hands share a frame.

The site gives no depth accuracy figure and no label for a clean plate, a degreased surface or a full rack, so whether those are resolvable in depth is Not stated. The site says that wet and reflective surfaces, such as a rinsed pan, a wet countertop and a steel sink, degrade active-stereo depth. How a stereo pair behaves on them is Not stated, and a kitchen spec should expect the same care. Capture at your own facility is listed as not offered.

The site describes two stereo setups and does not say which one a kitchen order uses. The hard-environments stack is a global-shutter 4K/60 head camera with a 120° lens, two 1080p/60 wrist cameras, a depth sensor at 848×480 and 30 fps, and 200 Hz 6-DoF IMUs. The off-the-shelf stereo head rig, dataset 06, is dual fisheye cameras at 1080p per eye, a 62 mm baseline, per-unit calibration, a 9-axis IMU and hand-tracking output.

Which rig, resolution and streams a kitchen order uses is Not stated on the site, and the third table below sets what is stated beside what is not. Intrinsics and extrinsics are re-solved at the start and end of every session, and streams are hardware-triggered onto one clock with a 2.0 ms cross-stream ceiling. The site does not state how capture hardware is protected from water or spray. The catalog states that a multiview rig adds synchronized third-person angles when the spec asks for them, and wrist cameras give a closer view of the hands.

MCAP is an open source container file format for multimodal log data, supporting multiple channels of timestamped pre-serialized data. It is serialization-agnostic, so messages can be Protobuf, DDS (CDR), ROS, JSON and more. Its design is row-oriented and append-only, it stores schemas alongside the data, and it offers an optional index plus optional LZ4 or Zstandard chunk compression.

Reader and writer libraries exist for C++, Go, Python, Rust, Swift and TypeScript, and the mcap CLI can inspect, merge and split files. The foxglove/mcap repository is MIT-licensed; that is the MCAP project’s licence, not the licence of a Firsthand delivery. The MCAP hub page and the glossary entry cover the format in full.

Firsthand offers MCAP delivery, and dataset 06 is stated as shipping as MCAP. For kitchen work the site states hand pose, a stereo-derived depth stream with confidence maps, IMU, contact events, action segments and per-frame instance masks elsewhere. What it does not state is which of those are channels in an MCAP file, how they are named, what encoding they use or at what rate.

No topic name, message schema or rate is stated on this page, and none should be assumed. Name the streams that matter in the skill spec and confirm them on a Spec Pilot batch. The fourth table below sets each stream beside what the site states about it.

Wet and reflective surfaces are the first risk. The site ships per-frame depth confidence maps for kitchen captures, so low-confidence regions can be masked rather than trusted, and per-frame instance masks for wet or reflective cookware, because masks propagated frame to frame do not track them well. It lists no clean, dry or degreased label, so what counts as a finished step is written into the spec up front.

Hands are the second. Fingers go behind plates, racks, pans and shelving, and a hose or scrub pad can hide the surface it is working. The visibility flag on each joint is the answer the site gives, and contact events mark when a hand meets an item. A spec can also ask for wrist views, so a grip the head camera loses is still recorded.

Calibration is the third, because stereo depth is only as good as the rectification behind it: calibration is measured at the start and end of every session under a 0.28 px RMS gate. An episode is also rejected when the manipulated object is out of frame for more than 15 percent of it or an undocumented bystander appears, and a reject log ships with every batch. Force and tactile readings are not among the listed streams.

For every delivered episode the site states that faces, plates and screens are blurred irreversibly, and that footage that cannot be de-identified is discarded. Who may be in frame, and how a kitchen’s own staff, menus or labels are handled, is agreed in the spec.

The site states no cleaning-standard, chemical, throughput, accuracy, food-safety or certification claim for these rows, so this page describes none.

Off-the-shelf covers what is already in stock: the stereo category lists the stereo datasets and hand-tracking video, and only dataset 06 is stated as MCAP. This page does not claim off-the-shelf stereo coverage of the kitchen rows. Custom collection covers the rest: custom collection at scale through a network of thousands of capture providers, for a consistent, recurring data flow to labs.

Where coverage is deep, the median time from signed spec to first validated batch is a median of 48 hours; where it is thin, turnaround runs three to four weeks. The site does not say which speed applies to a stereo kitchen order, so ask when you request the quote. Collections are billed per validated hour.

Describe the stations and their order, the ware, racks, hoses, degreaser, pads, brushes and mops and their start state, what counts as a finished step, and the variation your pipeline is missing. Then name the streams you want in the file, the topic naming and message encoding your reader expects, whether calibration ships inside the file or beside it, and whether MCAP is the only delivery or sits beside RLDS, LeRobot or WebDataset.

Most programs begin with a Spec Pilot, a small first batch that proves the spec and accept criteria on real footage before you scale. The fifth table below shows what each spec element decides.
