The invention relates to a remote gait acquisition and analysis system applied to a home or community environment. The remote gait acquisition and analysis system comprises a data acquisition device,a cloud data analysis device and a doctor end data processing device. The gait parameters of the testee are obtained by analyzing the remotely collected color image and depth image at the cloud end, and a doctor logs in the cloud end through a network to receive the gait parameters, so that the testee can be analyzed and diagnosed. According to the invention, the data analysis device is arranged at the cloud end, so that data acquisition is not limited by regions, examination is convenient, the software complexity of a doctor end is reduced, convenience is brought to doctors and patients, andthe requirements of convenience, rapidness, accuracy and low cost are met.
