What does ultrasonic angle measurement mean?

Ultrasonic angle measurement is a technology that uses ultrasonic waves to measure, calculate and control the relative angle of an object or system in space. By sending ultrasonic signals to objects and receiving the signals reflected by the objects, the angles between objects can be determined according to the time stamp difference and amplitude of the reflected signals.

This technology is widely used in unmanned aerial vehicles, robots, self-driving cars, aerospace, medical equipment and other fields, and can realize autonomous navigation, obstacle detection, positioning and tracking, safety monitoring and precise control. For example, in the field of unmanned aerial vehicles, ultrasonic angle measurement can help unmanned aerial vehicles obtain accurate altitude and position information, and realize safe take-off and landing and obstacle avoidance; In the field of medical equipment, ultrasonic angle measurement can be used to diagnose and quantify the range of motion of joints.

It should be noted that the reliability, accuracy and stability of ultrasonic angle measurement depend on many factors, such as sensor quality, environmental interference, reflective medium, attenuation loss and so on. Therefore, it is necessary to select an appropriate ultrasonic sensor, optimize the measurement algorithm, and rationally debug and calibrate the equipment in specific applications in order to obtain more accurate and reliable measurement results.
