The Upper Eye Field Camera simulates an insect's compound eye through an array of millions of tiny lenses, each of which represents a separate sub-viewing angle. The millions of different viewing angles give the Light Field Camera the ability to accurately perceive objects in three dimensions, comparable to that of an insect.

Light field camera passive optical measurement, without active light casting and mechanical displacement mechanism, a single device single shot, within 50 milliseconds can be three-dimensional imaging. Hundreds to tens of millions of compound-eye lens units simultaneously image the target from multiple viewpoints, and the dense spatial sampling capability of the light field enables three-dimensional measurement accuracy of up to 800 nanometers. "Shoot first, then focus arbitrarily", "hundreds of different viewpoints image acquisition at the same time", can be in the target object has a blockage, material reflections, space is narrow, hole depth to width ratio of large and other special working conditions three-dimensional imaging, with conventional three-dimensional vision program can not be replaced by the advantage of the It has advantages that cannot be replaced by conventional 3D vision programs.

At the level of light field algorithms, Eimage's R&D team has invested a lot of time in the development and iteration of light field depth computation, light field rendering algorithms, light field calibration, and scale calibration algorithms, which started in 2012 while at Shanghai Jiaotong University. He has published dozens of international papers and patents and English books. And in 2018, he won the world's first place in the international light field ranking 4D Light Field Benchmark published VOMMAnet. The related results have supported the research of many National Natural Science Foundation of China projects and major special projects.
