Method and device for estimating the posture orientation of the object in image are described. According to the method, an image feature of the image is obtained. With respect to each of a plurality of orientation classes, 3-D object posture information corresponding to the image feature is obtained based on a mapping model corresponding to the orientation class, for mapping the image feature to the 3-D object posture information. A joint probability of a joint feature including the image feature and the corresponding 3-D object posture information for each of the orientation classes is calculated according to a joint probability distribution model based on single probability distribution models for the orientation classes. A conditional probability of the image feature in condition of the corresponding 3-D object posture information is calculated based on the joint probability for each of the orientation classes. The orientation class corresponding to the maximum of the conditional probabilities is estimated as the posture orientation of the object in the image. |
