Intelligent Calibrated Lenses
Theia’s IQ Lens™ System with intelligent, motorized lenses enables precise, programmable, computer-controlled focus, zoom, iris and filters with SDK in Python, C++ or Linux for fast integration and deployment. Lens intelligence lets you calibrate the lens with your sensor, and the intuitive GUI provides lens control on demand. Modular components allow flexible configuration for integration and embedded vision.
Theia Technologies’ IQ Lens™ System combines a motorized lens with calibration data, software and motor control board to form an intelligent, modular, and configurable system. Theia’s TL1250P-IQ lens is a 12–50mm 4K, 300 lp/mm telephoto with zoom, focus, iris; while the ML410P-IQ is a 4–10mm 4K, 300 lp/mm mid-focal lens with the same motorization. Both support sensors up to 1/1.7", integrate with Theia’s Python or C++ modules and motor control boards, and are calibrated for precise remote control. Optional integrated NIR bandpass and longpass filters are available and currently available are models in 850 and 940nm, additional wavelengths are also possible.
Theia’s motorized IQ Lenses provide the ability to adjust the zoom and focus remotely, offering enormous flexibility in the placement of imaging systems requiring variable camera positions and/or object distances simplifying camera setup and installation in applications that have remote or difficult-to-access set up locations. Remote zoom and focus permit fine tuning of object resolution in dynamic environments and applications as in autonomous mobile robots (AMRs), UGV’s, Cobots, Traffic Gantries for ANPR/LPR, ITS and Tolling applications for example.
Theia’s motorized, NIR corrected IQ Lenses offer the ability to switch between transmitting visible light and Near IR light, enabling high image detail in multi-spectral applications, accurate color rendition in visible light, and improved sensitivity in NIR light for a variety of applications including produce inspection and grading, agricultural crop monitoring, Automated Number Plate Reading (ANPR) and many more.
Theia’s IQ Lens™ includes calibration data in a computer-readable .JSON formatted data file to enable enhanced image performance and image processing speed. Calibration curves are monitored from lens lot to lot to verify the continued accuracy of the curves; the most recent data file is provided with lens purchase, available through cloud download. Theia’s IQ Lens™ calibration data includes an average measured zoom/focus tracking curve which can be used to quickly find focus when changing zoom position, or to set the focus at a known zoom position. The IQ Lens™ calibration data provides intelligence that enables optimal image quality and easy imaging system setup.
Theia’s IQ™ Lens System comes with an easy-to-use software development kit (SDK) that translates engineering parameters into motor steps and motor steps into lens commands for quick and easy integration into the imaging system. With the system’s SDK, engineering units are automatically converted from intuitive concepts into motor steps using Theia’s lens control library and GUI without complicated external calculations, curve fitting, or interpolation. The SDK is designed for use with USB communication protocol. It can be modified by the customer to support I2C and UART protocols.
The system also includes the MCR IQ™ Motor Control Board with software module and GUI to convert motor steps into machine commands and to move the lens to desired positions. Purchase of the IQ Lens™ and MCR IQ™ Motor Control Board includes a royalty free license to use the Python or C++ software modules and GUI applications.
Theia’s IQ Lens™ System offers a modular design with separate components allowing flexible configuration inside the hardware envelope. The TL1250P-IQ 12-50mm telephoto lens is compact at less than 52mm lens length and lightweight at only 74 grams, while the TL410P-IQ (CS mount version) and ML410P-IQ (C mount version) 4-10mm varifocal lenses are less than 47mm lens length and weigh 75 grams. Theia’s MCR IQ™ motor control board is only 25mm x 60mm to fit into small enclosures and lightweight at only 10 grams. With USB, UART or I2C communication protocols the IQ Lens™ and MCR IQ™ motor control board offer convenient and flexible integration into the imaging system.
Theia’s IQ Lens™ System with motorized varifocal lenses, motor control board, average calibration data, and software application saves the user considerable development effort and cost, speeding time to market. The system provides convenience, flexibility and optimized image quality in a cost-effective package to support today’s demanding machine vision applications.
