From 'Seeing' to 'Understanding', SingTown Technology Drives Visual Advancement

In intelligent service robot applications, environmental perception and target recognition are key technologies for achieving autonomous interaction and task execution.

The robot needs to recognise multiple objects in complex indoor environments, such as room doors and their open or closed status, human gestures, QR codes, and typical objects in daily scenarios (e.g., tabletops, items, markers, etc.). To achieve this, the service robot manufacturer plans to adopt SingTown Technology's OpenMV smart camera to build a multi-object recognition system based on machine vision. Installed on the robot's head or body, this system can capture images in specified directions in real-time according to main control instructions, identify target categories, dimensions, and colour features, and return the recognition results to the host for path decision-making, task triggering, or voice interaction responses. Additionally, it can be extended to recognise QR codes, enabling navigation positioning, task identification, or authentication, thereby assisting robots in achieving higher-level intelligent behaviours in areas such as daily life, security, and guided tours.

Service robot manufacturers have developed a multi-target recognition system based on SingTown's OpenMV intelligent camera, enabling service robots to achieve intelligent visual perception in complex scenarios. This system integrates computer vision, AI image recognition, template matching, colour tracking, morphological analysis, and QR code decoding algorithms.

The system captures real-time images of the robot's forward field of view via the camera. Edge-side AI utilises an object detection model to identify object edges and shape features, enabling the determination of door positions and their open or closed status. Through colour segmentation and brightness variation analysis, it can recognise the colours, dimensions, and relative distances of various objects.

The robot can also recognise hand gestures. At close range, the system uses contour tracking and keypoint matching algorithms to identify common actions such as raising a hand, pointing, or waving. Additionally, the built-in QR code recognition function enables the robot to identify navigation points or receive task instructions.

This system enables edge deployment, with its algorithm operating efficiently in embedded environments, achieving a frame rate of over 20fps and a recognition latency below 100ms.

The system can communicate with the master microcontroller via serial port, I²C, or CAN bus, outputting recognition categories, dimensions, colours, and status information to enable intelligent linkage with the host.

Test results indicate that the solution developed based on SingTown Technology's OpenMV smart camera achieves an indoor recognition accuracy rate exceeding 92% under varying lighting conditions. It supports multiple task scenarios, such as home companion robots, security patrol robots, and guide robots, significantly enhancing the robot's environmental understanding and interaction capabilities.
