Integrated imaging system transverse position error correction method based on macro lens array

Abstract

The invention relates to an integrated imaging system transverse position error correction method based on a macro lens array. The method further comprises the steps that the position of a convergent point of a light cone emitted by a point on the LCD plane in the center depth plane after passing through the macro lens array and the position of a standard convergent point are obtained; the standard convergent point is formed by converging light cones emitted by points on the LCD plane on a central depth plane after passing through the macro lens array; measuring the transverse position error of the macro lens array according to the average value of the distance between the position of each convergent point and the position of the standard convergent point and the corresponding variance, and determining a measurement result; judging whether the measurement result exceeds a threshold value or not; if so, measuring an axial position error and a transverse position error of the macro lens array, and further performing correction according to the axial position error and the transverse position error of the macro lens array; and if not, carrying out integrated imaging. The workload can be reduced, and the display effect of integrated imaging is improved.

Description

technical field [0001] The invention relates to the field of integrated imaging, in particular to a method for correcting lateral position errors of an integrated imaging system based on a macro lens array. Background technique [0002] With the continuous development of research, more and more researchers have begun to use macrolens arrays in large-format integrated imaging systems. The macro lens array is usually mechanically embedded on the hard substrate. Its advantages are low cost, mature manufacturing process, and can realize integrated imaging display with large format and wide field of view. The disadvantage is the position error caused by installation or use. larger. Therefore, in order to obtain a better display effect, it is necessary to measure and correct the position error of the macrolens array. [0003] However, there are problems of heavy workload and low precision in the prior art. Therefore, in order to solve the above problems, a method for correcting ...
