Abstract: A computer-implemented method, system and computer program product for improving accuracy of a vision model. Images of an object with a first set of perspectives are received from a dataset used to train the vision model. A three-dimensional model of the object is then generated using the images of the object from the dataset. Using the three-dimensional model of the object, images of the object with a second set of perspectives are obtained. For example, the second set of perspectives may include different perspectives than the perspectives of the object from the images contained in the dataset. The dataset used to train the vision model may then be augmented with such images of the object with a second set of perspectives. In this manner, the dataset used to train the vision model includes a greater number of perspectives of the object thereby improving the accuracy of the vision model.

Abstract: A structure of light box assembly is disclosed in the invention, which includes an upper plastic frame and a lower plastic frame, and each of them can be formed by a plastic sheet or two same plastic sheets. Besides, at least four supporting columns are used to connect and support the two plastic frames. In addition, a plurality of side plate, an upper cover plate, and a lower cover plates are separately installed according to different planes formed by each of the plastic frames and each of the supporting columns so as to construct a box body. Also, an erect diffusion plate is provided at each corner of the box body corresponding to the position of its relative supporting column so that each of the four diffusion plates is to cover the outer field of each of the vertical light tubes. Thus, uniformly distributed light can be provided, and a solid and uniform light source can be provided as well.
