Stereo Garment Sewing and Fabric Cutting Data

It is first-person video of a person doing garment production 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 Textile & Apparel Production. 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 Textile & Apparel Production under Manufacturing & Workshops. The catalog lists examples for the environment such as a garment factory, a sewing workshop, a fabric cutting facility, a textile mill and fashion manufacturing. "Garment sewing" is described as feeding fabric pieces through an industrial sewing machine to join seams and attach parts, and is rated Hard. "Fabric cutting" is described as laying out fabric, placing patterns and cutting pieces with shears or a cutting machine, and is rated Medium.

"Finishing and pressing" is described as pressing seams and finished garments on an industrial iron or press and folding or hanging them, and is rated Easy. "Textile mill operation" is described as loading yarn or fabric onto mill machines, monitoring runs and clearing faults, and is rated Medium. All four list a head-mounted phone or a multiview rig as the capture setup, and all four are Available on request.

Available on request is the status the catalog gives, and this page does not claim any active or completed collection for these rows. The site says nothing further about it, so what it means for a given order is confirmed when you request the quote. This page names only the tools and steps that appear in the rows: an industrial sewing machine, shears, a cutting machine, an industrial iron or press, mill machines, fabric pieces, seams, patterns, yarn and faults. The first table below reproduces the rows as the catalog states them.

The egocentric garment production page covers the same four rows as first-person capture and says nothing about stereo or MCAP. The egocentric sewing and textile handling page is wider: it covers a textile arts and stitching studio, the apparel production setting, leathercraft rows and a cloth bench, and its capture-stack section describes a head-mounted stereo rig as the instrumented tier. It has no MCAP treatment.

This page is the stereo and MCAP treatment of the Textile & Apparel Production rows, centred on garment sewing and fabric cutting. It does not repeat the studio, leathercraft or cloth bench rows, and the stereo commercial laundry and linen page covers laundry and linen rows in a different environment. The comparison table below sets the pages side by side.

Garment work is about where the hands, the cloth and the tool are relative to one another: whether the pieces are aligned at the needle, whether the pattern sits on the fabric, whether the shears or cutting machine are on the marked line. Cloth also has no fixed shape, and it changes shape from frame to frame. A stereo pair recovers depth from the calibrated frame pair rather than from a standalone depth sensor, so the cloth, the tool and the hands share a frame.

The site gives no depth accuracy figure and no label for an aligned seam, a placed pattern or a cut line, so whether those are resolvable in depth is Not stated. It does not state how a stereo pair behaves on fabric, thread or a moving needle either, and it says depth degrades on wet and reflective surfaces without saying anything about cloth. Which facilities a given program uses 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 garment 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 garment 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 cutting table or a machine the head camera sees only in part, 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 garment 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.

Soft material is the first risk. Cloth has no fixed shape, so the object being tracked changes between frames. The site ships per-frame instance masks rather than propagated ones for deformable objects, and it lists no seam, stitch-length, thread-tension, needle-position, pattern-placement or cut-accuracy label, so what counts as a joined seam or a finished cut is written into the spec up front.

Hands are the second. One hand guides the cloth while the other holds a piece or a tool, and fingers are hidden under or behind the material. 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 garments or patterns belonging to a facility are handled, is agreed in the spec.

The site states no garment type, production-rate, throughput, accuracy, safety or certification claim for any of 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 coverage of the garment 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 garment order, and the rows are Available on request, so ask when you request the quote. Collections are billed per validated hour.

Describe the stations and their order, the fabric pieces, patterns and tools 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.
