Stereo Commercial Laundry and Linen Data

It is first-person video of a person doing commercial laundry and linen work, recorded from their own point of view with two calibrated cameras and with hand pose and sensor streams alongside. The tasks are the six rows the site’s catalog lists for it in Commercial Laundry & Linen Service and Hotel & Lodging. 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.

Six, all rated Easy. Four are in Commercial Laundry & Linen Service under Facilities & Cleaning, and all four are Active collection. "Sorting" is described as sorting incoming laundry by colour, fabric and customer into carts and bins. "Washing" is described as loading sorted laundry into industrial washers, adding detergent and starting the cycle. "Folding" is described as folding clean linens and garments on the table or feeding them into the folding machine. "Pressing" is described as pressing garments and linens on a steam press and hanging or folding them.

Two are in Hotel & Lodging under Hospitality & Events, and both are Ready to deploy. "Industrial Washer/Dryer Operation" is described as loading and unloading industrial washers and dryers, adding chemicals and setting the cycles. "Iron and fold linens using an industrial press and folding table" is described as feeding linens through the industrial press and folding them on the folding table. All six list a head-mounted phone or a multiview rig as the capture setup.

This page names only the tools and steps that appear in those rows: carts, bins, industrial washers and dryers, a folding machine, a table, a steam press, an industrial press and a folding table, and sorting, loading, unloading, setting cycles, feeding, pressing, hanging and folding. It makes no claim about detergents, chemicals, cycle settings or load sizes. The first table below reproduces the rows as the catalog states them.

The egocentric commercial laundry and linen page covers the same laundry rows as first-person capture with ten streams, and also covers further hotel linen rows and a staged towel and linen set. It has no stereo or MCAP treatment. The household laundry folding page covers folding and sorting in homes, and the ironing and garment handling page covers pressing, hanging and sorting garments. Neither has a stereo or MCAP treatment either.

This page is the stereo and MCAP treatment of just the six rows named above. It does not repeat the linen change, bed making or towel set rows. The comparison table below sets the pages side by side.

Laundry work is about the state of fabric and of the machine in front of it: whether linen is in a cart or a washer, whether a sheet is on the press or folded on the table. A stereo pair recovers depth from the calibrated frame pair rather than from a standalone depth sensor, so the linen and the machine share a frame with the hands. The site gives no depth accuracy figure and no label for a fold, a load or a press state, so whether those are resolvable in depth is Not stated.

The site does not state how a stereo pair behaves on fabric, inside a washer door or near steam, so this page promises nothing there. Which facilities a given laundry program uses is not stated either, and is agreed in the spec. Capture at your own facility is listed as not offered.

The site describes two stereo setups and does not say which one a laundry 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 laundry 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 catalog states that a multiview rig adds synchronized third-person angles when the spec asks for them, which a spec can use for a station the head camera sees only in part.

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 laundry and linen work the site states hand pose, a stereo-derived depth stream, 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.

Fabric is the first risk. A sheet or towel folds, drapes and bunches as it is handled, and part of it is always under another part. The site ships per-frame instance masks for that reason, and the site lists no linen-state, load-quality or fold-quality label, so what counts as a sorted cart, a loaded washer or a finished stack is written into the spec up front.

Hands are the second. Two hands hold, lift, smooth and feed linen, and the fabric edge and fingers are hidden under or behind the other hand. 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. Names on linen tags, room numbers and patient identifiers are not listed as blur categories on the site, so this page does not claim they are blurred. Who may be in frame, and how customer items are handled, is agreed in the spec.

The site states no hygiene, infection-control, chemical, detergent or throughput claim and no certification for any laundry row, 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 coverage of the laundry 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. Four of the six rows are Active collection and two are Ready to deploy, but the site does not say which speed applies to a stereo order, so ask when you request the quote. Collections are billed per validated hour.

Describe the stations and their order, the linen items 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.
