1, the difference between ultrasonic radar and visual sensors: the principle is different. Visual sensors are vision originated from the biological world to obtain information about the external environment, is the most effective means of obtaining information in the natural world organisms. Ultrasonic radar is the use of measuring the time difference between the ultrasonic transmitter and receiver pulses, combined with the speed of ultrasound transmission in the air to calculate the distance. This is the biggest difference between the two.
2, ultrasonic radar and visual sensors: different applications. Visual sensors are widely used in the military, scientific research, industry, agriculture, business and other fields and sectors of the detection system, becoming the essential centerpiece of modern detection equipment. Ultrasonic radar is mainly used in robotics, industrial ranging, medical ranging and other fields.
