背景技术Background technique
影像测量仪又名自动影像测量系统，它克服了传统投影仪的不足，是集光、机、电、计算机图像技术于一体的新型高精度、高科技测量仪器。由光学显微镜对待测物体进行高倍率光学放大成像，经过CCD摄像系统将放大后的物体影像送入计算机后，能高效地检测各种复杂工件的轮廓和表面形状尺寸、角度及位置，特别是精密零部件的微观检测与质量控制。可将测量数据直接输入到AUTOCAD中，成为完整的工程图，图形可生成DXF文档，也可输入到WORD、EXCEL中，进行统计分析，可划出简单的Xbar-S管制图，求出Ca,等各种参数。Image measuring instrument, also known as automatic image measuring system, overcomes the shortcomings of traditional projectors and is a new type of high-precision, high-tech measuring instrument integrating optical, mechanical, electrical, and computer image technologies. The optical microscope performs high-magnification optical magnification imaging on the object to be measured. After the enlarged object image is sent to the computer through the CCD camera system, it can efficiently detect the contour and surface shape, size, angle and position of various complex workpieces, especially precision Microscopic inspection and quality control of parts. The measurement data can be directly input into AUTOCAD to become a complete engineering drawing. The graphics can be generated as DXF files, and can also be input into WORD and EXCEL for statistical analysis. Simple Xbar-S control diagrams can be drawn to calculate Ca, and other parameters.
目前影像测量仪的精度和速度要求越来越高，当滚珠丝杆机器螺母来快速移动机床工作台，会产生误差，此时采用直线光栅尺就能有效消除潜在的误差源。At present, the accuracy and speed requirements of image measuring instruments are getting higher and higher. When the ball screw machine nut moves the machine tool table quickly, errors will occur. At this time, the use of linear grating scales can effectively eliminate potential error sources.
但是现有影像测量仪采用的直线光栅尺缺陷是每次开启或复位时都要找基准零位，即读数头要沿尺身来回运动，通常说的找尺中，浪费时间，采用这种直线光栅尺快速运动或受到电磁干扰会出现失步丢数，影响精确度。另外这种直线光栅尺在使用时，现场的环境温度和实验室的标准温度有偏差，会导致直线光栅尺的材料热涨冷缩带来测量误差。而在很多情况下要知道读数头的绝对位置是非常必要的，可以快速的确定直线光栅尺的绝对位置，在使用时就会更加方便，因此，如何克服上述技术问题成为本领域技术人员努力的方向。However, the defect of the linear grating ruler used in the existing image measuring instrument is that the reference zero position must be found every time it is turned on or reset, that is, the reading head needs to move back and forth along the ruler body. Usually, it is a waste of time to find the ruler. Using this kind of straight line If the grating ruler moves quickly or is subjected to electromagnetic interference, it will lose steps and numbers, which will affect the accuracy. In addition, when this kind of linear grating scale is used, the ambient temperature on site and the standard temperature of the laboratory will deviate, which will cause measurement errors caused by thermal expansion and contraction of the material of the linear grating scale. In many cases, it is very necessary to know the absolute position of the reading head. The absolute position of the linear grating scale can be quickly determined, which will be more convenient in use. Therefore, how to overcome the above technical problems has become a challenge for those skilled in the art. direction.
