Embodiment Construction
[0029] Embodiments of the present invention will now be described in more detail hereinafter with reference to the accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.
[0030] The present invention only studies the evaluation method for short-distance parallel shooting, combining parallel cameras (such as figure 2 ) shooting characteristics and existing shooting criteria, explored and expanded the impact of multiple stereo camera shooting parameters on image quality, and established a corresponding model. At the same time, based on the limitation of the scene parameters of the close-up parallel shooting, an objective evaluation method for the quality of the close-up parallel shooting of the stereo c...

The invention belongs to the technical field of three-dimensional-image acquisition and relates to an objective evaluation model method for the short-range shooting quality of a stereo camera. The method includes the following steps: determining an evaluation and scoring standard for the short-range parallel shooting quality of the stereo camera: setting the shooting distance as h, camera distance as d, camera focal distance as f and selecting a relational expression of f and d / h as an index of stereo image quality evaluation; selecting a ratio CE / BF of a binoculus overlapping region and a binoculus view field as another objective evaluation index; establishing a corresponding relation of the two objective evaluation indexes: the CE / BF value range and an objective evaluation value of the stereo image quality; using the stereo camera to shoot stereo image pairs under a short-range parallel setting condition; and according to the values of the two indexes, obtaining the objective evaluation result of the shot stereo image pairs. The objective evaluation model method for the short-range shooting quality of the stereo camera is capable of effectively judging the quality of stereo images shot by the stereo camera in a short-range and parallel manner. The method is capable of effectively evaluating the quality of stereo images shot by the stereo camera in a short-range and parallel manner.
Description
technical field [0001] The invention belongs to the technical field of three-dimensional image acquisition, and in particular relates to an objective evaluation method for close-distance parallel shooting quality of a stereo camera. Background technique [0002] With the development of stereoscopic technology, the processing technology of stereoscopic (3D) images is becoming more and more mature, and the sources of stereoscopic images in various countries are increasing day by day, satisfying people's desire to see 3D images on the screen. However, when people watch certain film sources, they may experience discomfort symptoms such as dizziness, nausea, and decreased body balance. Many people attribute this to insufficient stereoscopic image processing technology or insufficient display technology. Research and establish a corresponding evaluation theory system. However, these evaluation systems still cannot completely solve all the symptoms of discomfort during viewing, be...
