APPARATUS TO MEASURE GRADIENT USING ULTRASONIC SENSOR AND METHOD TO MEASURE GRADIENT

Ultrasonic Slope Measurement Device

This technology concerns a device and method for measuring inclination using an ultrasonic sensor. More specifically, it describes a method for measuring inclination by transmitting and receiving ultrasonic waves via an ultrasonic sensor while positioned at a distance from the inclined surface.

Conventional methods for determining inclination using accelerometers and gyroscopes suffer from errors during the integration process, limiting their ability to accurately determine the ground's inclination. Therefore, we propose an inclination measurement device and method utilizing an ultrasonic sensor.

This technology enables safer and more accurate inclination measurements compared to conventional methods, as it can measure the slope by transmitting and receiving ultrasonic waves via an ultrasonic sensor while positioned away from the inclined surface.

Key Features:

• Transmits and receives ultrasonic waves from the device body towards the surface whose inclination is to be measured.
• Constructs the equation of a plane using distance data obtained from multiple ultrasonic sensors.
• Calculates the inclination by determining the angles formed by the x-axis, y-axis, and z-axis.
• The inclination measurement device can be conveniently mounted on a drone for use.
