Underwater imaging sonar measurement calibration device and method

The invention discloses an underwater imaging sonar metering calibration device which comprises a test pool, a track module and a calibration module. The track module is arranged at the top end of the test pool and provides different positions and postures for the sonar device; the track module comprises first tracks which are respectively arranged on any two symmetrical sides of the test pool, and a second track is vertically connected between the two first tracks in a sliding manner; the second track is slidably connected with two test platforms, and the sonar device is installed at the bottom end of any test platform through a connecting rod. The calibration module is used for receiving and calibrating the sonar device; the calibration module comprises a receiving assembly and a processing assembly which are electrically connected. The receiving assembly is fixedly installed at the bottom end of the other test platform and corresponds to the sonar device. The imaging sonar measurement calibration device di
