[0076] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0077] The present invention provides a neural network-combined acquisition method based on the idea of "actively irradiating a number of specific patterns on an object, simultaneously collecting photos, and obtaining the normal vector of the object by calculating the obtained photos". Further, the method uses the obtained normal vector to optimize the model of the object. This method can also obtain material feature information while obtaining the normal vector. Finally, high-quality geometric and material collection results are obtained jointly. The specific implementation of the three parts is described in detail below:
