The invention provides a grab ship unloader accurate positioning system which comprises a mechanism positioning unit, a grab pose detection unit, a scanning recognition unit and a data acquisition unit. The mechanism positioning unit is used for carrying out trolley position value calibration by arranging a laser ranging device on a trolley mechanism and carrying out cab position value detection by adding a Gray bus coded scale in a cab; the grab bucket pose detection unit is used for detecting the grab bucket operation space position and the grab bucket pose by arranging a laser scanning device and a visual identification device on a cab platform; the scanning identification unit is used for performing real-time detection on a ship, a hatch and materials by arranging laser scanning devices at a cab platform and a main beam twisting point position; the data acquisition unit comprises a PLC module and a communication module. According to the invention, accurate positioning, detection and identification of each mechanism, a grab bucket, a ship, a hatch and materials of the grab bucket ship unloader can be realized.
