针对发射光轴的双光楔校正结构,提出了一种激光测距机光轴平行性智能检测校正方法。建立了光轴平行性偏差量与双光楔结构旋转角度之间的数学模型,利用CCD图像传感器和数字图像处理技术得到激光发射光轴与瞄准光轴之间的平行性偏差,依据所建立的数学模型解算出双光楔需要调整的角度值,结合机械校正装置转动相应的角度,实现了激光测距机光轴的校正。该方法同样适合于其他具有双光楔调整结构的光学仪器。 Aiming at the double wedge correction structure of the emitted optical axis, an intelligent detection and correction method for the optical axis parallelism of laser rangefinder is proposed. The mathematical model between the deviation of the optical axis parallelism and the rotation angle of the double wedge structure was established. By using the CCD image sensor and digital image processing technology, the parallel deviation of the laser emission aiming axis was obtained. The mathematic model solves the angle value that the double wedge needs to be adjusted, and corrects the optical axis of the laser range finder by combining the angle of the mechanical correction device. This method is also suitable for other optical instruments with double optical wedge adjustment structure.
