Melexis evaluation kit supports ToF sensors
Melexis is supporting its time-of-flight (ToF) sensing technology with the EVK75023 evaluation kit which accompanies its MLX75023 QVGA (320x240pixels) resolution ToF sensors.
This new hardware platform enables implementation of more advanced human machine interfaces (HMIs).Co-developed with BlueTechnix, the EVK75023 is a 130x105x60mm board for assessment of ToF sensing capabilities under challenging conditions, where the detrimental influence of ambient light variations must be addressed. Thanks to the constituent MLX75023 imaging device, it can deal with up to 120klux of background light.
The EVK75023 has a high bandwidth Gigabit Ethernet interface, through which real-time 3D images are output at frame rates of up to 60fps, according to Melexis. These can be used to recognise complex gestures. Via a C-based API or via the Matlab SDK, users can easily develop their own communication interfaces.
The platform consists four main elements:
- A pair of illuminating units – each with a set of six LEDs capable of producing a peak optical output of 10W
- A sensor board – incorporating the MLX75023 sensor, a standard M12 lens mount plus objective with a field of view up to 60°, a quad-channel data converter and programmable logic (through which both the sensor and the LEDs are controlled)
- An ARM-based processing board – featuring an i.MX6x Freescale microprocessor, which is responsible for compiling the acquired ToF data then subsequently communicating this to a laptop, via the Gigabit Ethernet connection, for analysis
- An interface board – on to which all of these different subsystems are placed.
