Sipeed MaixSense A010 with LCD screen - 3D Sensor Module Based on BL702 and TOF Camera.

MaixSense-A010 is an extremely cost-effective 3D sensor module composed of BL702 + OPNOUS 100x100 TOF launched by Sipeed, which supports a maximum resolution of 100x100 and 8-bit precision, and comes with a 240x135 pixel LCD display to preview the depth map after colormap in real time.

MetaSense A010 is an all-in-one, low cost, flexible and easy to use 3D ToF(Timeof-Flight) solution for loT applications. It consists of an on-board 100x100 array ToF sensor and ToF processor, which combines ToF sensing, ToF signal processing and application algorithm on a single board. It integrates the following algorithms: Specific applications, such as ranging, multi area human body positioning and sensing, posture monitoring, posture control, keystone correction, etc. These features are widely used in loT applications like white goods, L aser TV, smart projector, smart illumination, smart parking, smart home facilitis.etc.

MetaSense A010 is power supplied via USB2.0, and it outputs ToF depth data and RGB image at a speed of 30fps. With its sophisticated optic, electronic and high-accuracy algorithms are able to calculate depth data as accurately as at the millimeter level. Dual support ROS system, open ROS1 + ROS2 access function package, can quickly obtain depth data and depth map.

MS-A010 has strong compatibility and is based on serial protocol. It can be connected to single-chip development boards such as K210 bit or Linux development boards such as Raspberry Pi for secondary development. It uses the serial port protocol to provide interfaces and transmit data. The physical interfaces we provide include type-c (virtual serial port) and a 1.0mm 4pin motherboard (UART), which can obtain depth map data for integration.

Low and customizable power consumption: supporting lithium battery charge management
Outdoor compatibility: The hard shell is suitable for outdoor scenes

what is TOF technology?

It is a method of distance measurement, which calculates the distance between the two by measuring the "time of flight" of signals such as ultrasonic/microwave/light between the transmitter and the reflector. It is the TOF sensor that can achieve TOF ranging. The most commonly used is infrared or laser ranging.

There is a difference in the distance between the objects. The module displays the cold and warm colors through the difference of the captured depth values. The cool and warm colors change with the mapping of the distance.
