3D Sensor Systems

People and Object Detection via Ultrasound - Small, Robust, Precise


Toposens creates groundbreaking new technology for machine vision. We are not trying to make old things better - instead we use new methods to give you the 3D sensor that you have been waiting for. 

Vision for Technology

Toposens follows an unusual path – we provide Vision for Technology without using any optical components!


Our sensor follows the principles of the echolocation of a bat, who can see tiny objects by emitting ultrasound signals and receiving their reflections. We adapted this method and developed a small sensor system based on ultrasound. The Toposens 3D sensor therefore enables machines and robots to better perceive their surroundings without the disadvantages inherent to optical systems.


Toposens makes it possible to see with sound – an ability that brings with it several important advantages that have not been combined into one single 3D sensor system up to now.

Sensor Applications

Due to its innovative approach, the Toposens 3D sensor opens up new fields of application. Its characteristics enable the operation of the sensor also under difficult environmental circumstances. The innovative sensor can perceive 3D positions of objects and people.

Autonomous Driving Sensor

Toposens 3D ultrasound sensors can monitor the near-field surrounding of autonomous cars in a detailed 3D image. The 3D sensors thereby enable autonomous parking and collision avoidance in difficult and dense traffic situations.

3D sensor precision



The innovative sensors of Toposens bring together characteristics, which have not been combined into one single sensor system to this date.

  • The 3D ultrasound sensor is small in size and lightweight plus it only needs very little energy to be operated. It is therefore ideal for mobile applications.
  • Due to the use of sound, the sensor is very robust and not dependent on external factors, such as lighting conditions, rain, dust or dirt.
  • Since no optical components are used for the sensor, the employment of the sensor is trouble-free and also suitable for sensitive surroundings (e.g. private home, workplace), because it provides maximum privacy protection.
  • Even though the sensor does not recognize people or objects, it can still determine 3D positions with very high precision.
