System and method for aligning measuring device, calibrating the relative position of lens and chart

Abstract

The present invention discloses a benchmarking measurement device, and a system and method of relative position of a calibration lens and a graphic card. The benchmarking measurement device comprises an adjustment mechanism and a benchmarking mechanism arranged on the adjustment mechanism, the benchmarking mechanism comprises a matrix and a laser range finding module and laser emission pieces which are arranged on the matrix, the laser beam axes of the laser range finding module and the laser emission pieces are all perpendicular to the benchmarking end face of the matrix, and there are at least three laser emission pieces; and the adjustment mechanism is configured to adjust and record the positions of the benchmarking mechanism at an X direction, a Y direction and a Z direction and the rotation angle of the benchmarking mechanism in a rotation plane. The benchmarking measurement device can determine the benchmark of a lens can conveniently perform benchmarking adjustment and adjustment data recording, and the system of the relative position of the calibration lens and the graphic card can rapidly, conveniently and accurately measure and calibrate the relative position of the calibration lens and the graphic card so as to facilitate improving the test precision of the lens, improve the lens assembling adjustment and test efficiency and guarantee the quality of electronic products.

Description

technical field [0001] The present invention relates to the technical field of optical detection, in particular to a benchmark measurement device; the present invention also relates to a system and method for calibrating the relative positions of a lens and a chart. Background technique [0002] Nowadays, many smart electronic products have camera functions, and the lenses with camera functions in these electronic products need to be tested for performance during the assembly and production process. In particular, the optical characteristics of the lens are tested to ensure the accuracy of the lens and maintain a good user experience. In the test of optical characteristics, the positioning accuracy of the relative position of the lens and the chart directly affects the accuracy of the lens. [0003] In the prior art, the relative position of the lens and the chart is mainly calibrated by a ruler or a laser distance measuring instrument, but it is difficult for a ruler or a ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the relative position of the lens and the chart is mainly calibrated by a ruler or a laser distance measuring instrument, but it is difficult for a ruler or a laser distance measuring instrument to find the lens reference through the chart, and the distance between the measured lens and the chart cannot be guaranteed. The distance between them is a vertical distance, and the lens cannot coincide with the central axis of the chart during measurement, so accurate measurement cannot be achieved

Especially for the board ruler, when the distance between the lens and the chart is far, the measurement accuracy cannot be guaranteed
