The present invention provides an object recognition method and device based on a human body action characteristic. The method comprises a step of receiving multiple frames of human body images about people to be identified collected by an acquisition device and capturing the area of a human body in at least one frame from the multiple frames of human images, a step of extracting the key point information of the human body from the captured area of the human body, and a step of using a trained model to obtain a people object identification result based on the extracted key point information. According to the method and the device, the people object identification is carried out based on the human body action characteristic, the defects in singlely using face recognition technology can be made up, and the accuracy of the people object identification is improved.
