In the wave of technological innovation, Norwegian startup Sonair is sparking a revolution in perception technology. They cleverly introduce ultrasonic technology into the field of autonomous hardware 3D computer vision, challenging the long-standing dominance of LiDAR. Sonair's founder and CEO Knut Sandven has proposed an audacious idea: using ultrasonic technology to read sound waves for detecting people and objects to achieve 3D imaging. This technology not only boasts low energy consumption and minimal computational requirements but also promises to be superior to currently widely used solutions.
