Embodiment Construction

[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0065] figure 1 It is a structural schematic diagram of an embodiment of the side-scan sonar image mosaic system of the present invention. The system of the embodiment of the present invention includes: sonar, an attitude sensor, GPS, a pan-tilt support, a pan-tilt controller, and a computer.

[0066] The sonar communicates with the computer through the network, the attitude sensor, GPS and the pan-tilt controller are respectively connected to the computer through the serial port, and the pan-tilt bracket is connected to the pan-tilt controller through the serial port.

[0067] The attitude sensor is installed in the cabin for measuring the attitude of the hull. Preferably, the attitude sensor is installed on the central axis of the hull.

[0068] The GPS is set in the cabin for recording the real-time position of the ship and obtaining the real-time posit...

Abstract

The invention discloses a side-scan sonar image splicing system and a side-scan sonar image splicing method. The system provided by the invention includes: an attitude sensor, a GPS, a computer, a pan-tilt controller, and a sonar fixed on a pan-tilt bracket on one side of the hull. The splicing method comprises the following steps: reading sonar file data; processing trajectory line data; scanningline groups; determining a bitmap range and a pixel position; processing the arrangement mode of the scanning lines, and performing affine transformation on the image coordinates. The invention combines the GPS information and the hull posture information to realize seamless splicing of side-scan sonar images, which improves the splicing speed and the adaptability of the system, and reduces the system cost.

Description

technical field [0001] The invention belongs to the technical field of acoustic image stitching, and in particular relates to a side-scan sonar image stitching system and a method thereof. Background technique [0002] In recent years, the economic value contained in the ocean has gradually been valued by human beings, and human beings have further intensified their efforts to develop the ocean. It is necessary to have a comprehensive understanding of the entire ocean topography in order to effectively explore and develop marine resources. The current oceanographic mapping technology mainly relies on sonar detection technology. Side-scan sonar is a kind of active sonar, which uses seabed backscattering to obtain topographic information of the seabed. [0003] Side-scan sonar systems are divided into two types according to the configuration of detection transducers: single-side and double-side. The double-sided towed side-scan sonar system needs to be combined with towed fis...
