The invention provides a method and a system for automatically compensating goods hoisting and goods unloading along with waves as well as a crane platform, wherein the method for automatically compensating goods hoisting along with waves comprises the following steps of: detecting hoisting-sinking displacement of a ship as well as height H0, in a ship hoisting-sinking process, of a highest point of a deck for loading and unloading goods; detecting a hoisting period Tx which corresponds to a hoisting state and a falling period Td which corresponds to a falling state as well as hoisting-sinking speed V0 of the ship; when the ship is in the hoisting period Tx or the falling period Td, controlling a suspension cable to drive the goods on the deck to hoist the goods at a first speed V1 for enabling height of the bottom surface of the goods to reach or exceed height H0, wherein the first speed V1 is greater than or equal to the hoisting-sinking speed V0 of the ship. According to the embodiment of the invention, the method and the system for automatically compensating goods hoisting and goods unloading along with waves as well as the crane platform can ensure that the goods do not collide with the deck in the hoisting and unloading processes of the goods, and therefore, the safety, during hoisting and goods unloading, of the goods and the deck is guaranteed.
