Title:
UNDERWATER DETECTION DEVICE AND UNDERWATER DETECTION METHOD
Document Type and Number:
Japanese Patent JP2020008519
Kind Code:
A
Abstract:
To provide an underwater detection device which enables a user to easily and individually distinguish a target displayed as a three-dimensional image and easily discriminate the target.SOLUTION: A transmission transducer 2 transmits a transmission wave to a transmission space under water. A reception transducer 2 generates a reception signal on the basis of a reflection wave including reflection of the transmission wave of a target under water. A beam forming section 9 performs beam forming processing for each of a plurality of reception spaces RS on the basis of the reception signal. A three-dimensional image data generation section 10 generates three-dimensional image data for displaying the target on a display section 5 on the basis of a result of the beam forming processing. A contour line video data generation section 11 extracts a contour line of the target in which an echo signal is detected in at least one reception space RS and generates contour line video data for displaying the contour line on the display section 5.SELECTED DRAWING: Figure 3
