Image processing model training method and three-dimensional object model construction method

The embodiment of the invention provides an image processing model training method and a three-dimensional object model construction method. The image processing model training method comprises the steps of determining a three-dimensional object model of a target object; rendering the three-dimensional object model, and determining a color image of the target object under at least one view angle; determining an object parameterized model of the target object according to the three-dimensional object model or the color image; rendering the object parameterized model, and determining a depth image corresponding to the color image; and according to the color image, the depth image and a target depth image corresponding to the target object, training to obtain an image processing model. According to the method, rough priori of object shape parameters and attitude parameters is provided for depth estimation by introducing a depth image obtained by an object parameterization model for rendering a target object, so
