S3D Measurement and Monitoring

Stereolabs Pure3D

Accuracy and reliability combined.

STEREOLABS paves the way for a new era of 3D production.

PURE is a unique SIP designed for 3D HD video analysis, automatic rig control and live processing.

Live Analyzer

Detect any type of camera mismatch in realtime, including geometric, color and depth issues

Automatic Rig Control

Set-up automatically rigs from major manufacturers: Element Technica, Stereotec, P+S, SwissRig .

Image Processor

Correct instantly residual mismatch with the most accurate and reliable digital correction

  1. HD/SD Dual I/O

    Simultaneously capture two HD or SD cameras and output corrected dual streams through SDI in various formats: dual left/right, side-by-side, above/below.

  2. Live Analysis

    Obtain all relevant information about your cameras and rig: roll, convergence, y-shift, zoom, focus, iris. Adjusting your stereo rig has never been easier.

  3. Quality Control

    Use PURE QC log reports to check if the recorded footage contains any alignment, color or depth errors and correct them in post.

  4. Automatic Rig Calibration

    Connect your rig to PURE through RS232 and calibrate your rig automatically. PURE profiles the lenses and controls I/O, Convergence, Zoom, Focus and Iris motors.


  5. Depth Control

    Precise control of the depth budget is paramount in Stereo3D. PURE included depth tools help you to control your parallax range, and warn you when 3D depth budget in-front and behind your display is exceeded.

  6. Automatic Mismatch Correction

    PURE corrects alignment errors automatically, down to subpixel accuracy. This image processing technology guarantees technically perfect stereo content, making it ideal for live broadcasting and 3D shooting environments.

Features

Find out why PURE is the most powerful SIP.

Designed for studio and mobile 3D production, PURE is one of the most accurate and reliable analyzer in the industry. Whether you need high precision analytics, automatic adjustment of your rig system or live image processing, you'll find it all in PURE.


High-end analytics

Accurate 3D rig calibration can be complex and time-consuming. PURE greatly simplifies this process by providing live analysis and exhaustive feedback about your rig configuration.

PURE is one of the most accurate and reliable stereo image analyzer in the industry. It allows the user to analyze and track in realtime the smallest optical or mechanical mismatch: roll, convergence, vertical shift, zoom, focus and iris data is provided, along with the depth structure of the scene to help set

IO and convergence. With PURE, any cinema or broadcast technician can expect to set up high-quality shots in just a few minutes.

PURE also streamlines the 3D workflow by recording and transmitting full rig and camera metadata information to remote systems and operators.

Three-digit accuracy

PURE is incredibly precise. It measures zoom, convergence, rotation and y-shift misalignments down to 1/100th of a unit.

Most stable analysis

Calibrating a rig can be difficult with fluctuating analysis values. PURE improved stability simplifies fine mechanical adjustments on 3D camera rigs.

Faster than ever

Benchmarks have shown a significant boost in speed for the new PURE release. Expect to reduce your set-up time even further.


Unique rig control

 

3D production costs can be substantially higher than 2D HD, due to the presence of extra crew members and longer shooting times. By introducing unique rig control capabilities, PURE finally makes the creation process much quicker and cost-effective for live broadcasts and feature films.

 

Designed in collaboration with major rig, camera and lens manufacturers, PURE rig control module can drive interaxial, convergence, focus, iris and zoom motors of most popular rigs and cameras.

 

For live broadcasts, PURE provides lens tracking features that allow to setup and configure any type of full servo lens pairs to match throughout their range. PURE automatically compensates for mechanical differences between the lenses, enabling flawless zooming across the entire focal range. Focus and convergence can also be tied together with zoom for easier control.

 

PURE sets new standards for 3D production.

Rigs with full lens, tilt, roll and height motorization can now be setup automatically by PURE and ready for shooting in less than a minute!

Lens Profiling

PURE brings unique lens profiling capabilities and enables automatic adjustment of zoom, focus and iris motors over their entire range.

Broadcast metadata

PURE generates and broadcasts metadata for use for live graphics, video assist and post production. 

Drive Popular Rigs

Through partnerships with Element Technica, Chrosziel and Cmotion, PURE can setup and drive all major 3D rigs automatically.

Hardware independent

PURE is camera and lens independent: it can match Panasonic, Sony, Grass Valley, Arri or RED cameras and all type of external lens, including Angenieux, Fujinon and Canon prime or servo lenses.


Leading video processor

PURE pushes the boundaries of high-quality 3D image processing. It detects in real-time stereo differences and can correct any geometric and color mismatch with subpixel accuracy by the push of a button.

 

PURE is a must-have tool for any broadcast television or feature film Stereo3D production. It integrates a series of tools to finely control the 3D effect, monitor depth and safe zones, and provide immediate Stereo3D viewing. It can be also be configured to input and output virtually any type of stereo content: Side-by-Side, Above/Below, Dual Left/Right…

 

By using massively parallel CUDA™ and OpenCL technologies, PURE delivers impressive video processing performance. Through our partnership with Bluefish444, frame delay is reduced down to a minimum.


Remote access to analytics
 

With the latest PURE Remote technology, remote access to analytics has never been this simple!
PURE Remote allows you to connect to PURE with an iPad or iPhone and display its live analysis anywhere on the field, making rig set up quick and simple.

PURE Remote is provided free of charge with PURE.
