Abstract

The invention relates to the technical field of three-dimensional stereoscopic display and measurement, in particular to a calibration method and a calibration device. The calibration method is applied to a calibration device for calibrating a projection display device. The calibration device comprises an image pickup module and a calibration module, wherein a light sensor is arranged in the imagepickup module. The projection display device comprises a light source array module, a micromirror array and a light reflecting plate. The calibration method and the calibration device provided by theinvention can control the deflection angle of the micromirror unit to be obtained, The light beam emitted from the micro-mirror unit can be emitted into the designated position of the light sensor, so that the light beam emitted from the micro-mirror unit can be emitted into the space position to be projected when the micro-mirror unit is actually used, thereby avoiding the display error of the formed three-dimensional virtual scene, and thereby realizing the accurate control of the projection display device.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display and measurement, in particular to a calibration method and device. Background technique [0002] The projection display device generally includes a light source array module, a micro-vibration mirror array, and a light reflection plate. The micro-vibration mirror array includes a plurality of micro-vibration mirror units, and the light reflection plate includes a plurality of micro-reflection units. The micro-reflection units on the light reflection plate are in one-to-one correspondence, and the light emitted by the light source array module is coupled into the micro-vibration mirror array through the light reflection plate, and the micro-vibration mirror array is controlled to project micro-vibration mirrors to multiple virtual object points in space. beams so that multiple beamlets projected onto each virtual object point form a launch beam. When the user receives the beam co...
