Time of flight sensor

sick time-of-flight sensor

So far in our blog series on 3D machine vision technologies, we have explored some of the main techniques used in machine vision, such as 3D Stereo Vision and 3D laser profilometry.

In this post we will cover the Time-of-Flight (ToF) technique, exploring the technology and how it can help us solve numerous machine vision problems.

The Time-of-Flight technique allows us to take 3D images without having to scan an object. This approach is based on illuminating an object with a modulated light source. The position of the object is determined by the travel time of a pulse beam sent by the emitter and its return to the sensor after being reflected by an object. Hence the name Time-of-Flight.

Historically, Time-of-Flight has raised questions about its accuracy and has generally been considered an inferior 3D technology with limited sensor technology that can only provide a poor degree of accuracy (1-2 cm) without offering a However, Sony’s DepthSense ToF sensors have revolutionized the technology, capable of providing millimeter accuracy, allowing the integrator to achieve more robust and precise measurements.

Many applications need to detect the presence of physical objects or the distance to them without touching them. This need to detect distance has led to several competing solutions, including the use of optical time-of-flight (ToF) sensors. While these sensors are accurate, they have been costly and complex to implement. However, there are recent solutions that have greatly simplified the use of this technology.

The list of products that use distance sensors includes autofocus camera systems, robots and drones, a variety of sanitary fixtures, and gate access sensors for automatic doors. These are just a few examples and the list continues to grow. Competitive distance sensing technologies start with simple ultrasonic and infrared sensors and gradually develop into more complex sensor systems, such as stereo video cameras with neural networks.
