The invention discloses a three-degree-of-freedom spherical movement platform, a yaw movement motor assembly is arranged on a base and drives a yaw driven disc to rotate around self axis by 360 degrees; the bottom of an annular outer ring is fixedly arranged on the yaw driven disc; the outer wall of an annular inner ring is provided with outer teeth meshed with a pitching driving gear; a pitching driving motor drives the annular inner ring to rotate around self axis by 360 degrees by the pitching driving gear; the annular inner ring is fixedly provided with two rolling connection assemblies; rod parts at two ends of a rolling spherical cabin are respectively arranged in respective corresponding rolling connection assemblies by bearings; a rolling driven wheel sleeves the rod part of one end of the rolling spherical cabin; a rolling driving wheel is arranged around the rolling driven wheel; a rolling driving motor drives the rolling driving wheel to rotate; the rolling driven wheel drives the rolling spherical cabin to rotate around self axis by 360 degrees. The coupling is eliminated, the cost, energy consumption and fault ratio are reduced and the maintenance interval time is prolonged.
