Gen 3 Single-chip QVGA time-of-flight - MLX75026

Product description

The MLX75026 QVGA is the second member of the third generation of fully integrated optical time-of-flight (ToF) sensor ICs. It is compatible with the MLX75027 VGA resolution ToF sensor IC. Target applications include automotive driver monitoring (DMS), in-cabin monitoring (ICM), exterior cocooning as well as robotics, autonomous transport (AGVs), people and 3D object detection in industry, retail, logistics and smart cities. In automotive interior sensing use cases, while one VGA resolution sensor covers the full interior of a car, the MLX75026 QVGA ToF sensor IC offers a similar resolution for single-seat areas e.g. for driver monitoring, body position, occupancy classification, etc.

The sensor features a QVGA (320x240) pixel array and comes in a small package size and small ¼” optical format. Its full compatibility with the VGA ToF sensor highly facilitates the reuse of existing software, which eases migration paths between cost-effective QVGA and more high-end VGA solutions.

Interior sensing (driver and in-cabin monitoring) with the latest time-of-flight technology

Product

During his online presentation at Autosens in September 2020, regional marketing manager for time-of-flight solutions at Melexis, Cliff De Locht, tells us more about the newest evolutions in time-of-flight (ToF) technology and the automotive interior sensing use cases this enables: you will learn about driver monitoring system (DMS) performance based on ToF cameras (world’s first ToF based DMS demonstrator) and emerging in-cabin monitoring (ICM) use cases with ToF cameras (world’s first “wide-FOV” ToF based ICM demonstrator).

3D ToF Sensor-based Eye-tracking Solutions for Driver Monitoring Systems (Demo)

Product

Eyeware and Melexis have joined forces to create an advanced driver monitoring system (DMS). This collaboration demonstrates the robustness and wider range of head movement that can be achieved using Time-of-Flight technology, compared with current driver monitoring systems.

Webinar - introduction to continuous wave time-of-flight

Product

Time-of-flight is gaining popularity in several domains such as the automotive (both interior and exterior use cases) and the industrial domain, but also in smart applications (e.g. smart vacuum cleaner). This webinar clarifies the concepts you need to know to understand the technology behind continuous-wave time-of-flight (cwToF), and especially the principle of the pixel. We also provide an overview of the cwToF system and recommendations to get started. The webinar is accessible to everyone with an interest in time-of-flight technology and visuals and animations are added to facilitate the explanations.
