Description

一种基于线激光拍摄成像的测量系统Measurement system based on line laser imaging 技术领域Technical field
本发明涉及一种非接触式尺寸测量系统,更具体地,涉及一种基于线激光拍摄成像的测量系统。The present invention relates to a non-contact size measurement system, and more particularly to a measurement system based on line laser imaging.
背景技术Background technique
非接触式尺寸测量装置以光电、电磁、超声波等技术为基础,在仪器的测量元件不与被测物体表面接触的情况下,即可获得被测物体的各种外表或内在的尺寸数据特征。非接触式尺寸测量系统与传统的接触式测距系统相比精度更高、操作更方便、安全系数更高、洁净度高、测量过程中对被测物的污染程度小,从而被应用于工业生产及科学研究的多个领域。The non-contact size measuring device is based on photoelectric, electromagnetic, ultrasonic and other technologies. When the measuring element of the instrument is not in contact with the surface of the object to be measured, various appearance or intrinsic dimensional data characteristics of the measured object can be obtained. Compared with the traditional contact distance measuring system, the non-contact size measuring system has higher precision, more convenient operation, higher safety factor, higher cleanliness, less pollution to the measured object during measurement, and thus is applied to the industry. Multiple areas of production and scientific research.
典型的非接触式尺寸测量方法如激光三角法、电涡流法、超声测量法、视觉成像测量法、超声波测量法等等,其中视觉成像测量法是指通过机器视觉产品(即图像摄取装置,分CMOS相机和CCD相机两种)将被摄取目标转换成图像信号,传送给专用的图像处理系统,根据像素分布和亮度、颜色等信息,转变成数字化信号,图像系统对这些信号进行各种运算来抽取目标的特征,进而根据判别的结果来控制现场的设备动作,在测量缺陷和防止缺陷产品被配送到消费者的功能方面具有不可估量的价值。Typical non-contact size measurement methods such as laser triangulation, eddy current method, ultrasonic measurement, visual imaging measurement, ultrasonic measurement, etc., wherein visual imaging measurement refers to the adoption of machine vision products (ie, image acquisition devices, Both the CMOS camera and the CCD camera convert the captured target into an image signal, which is transmitted to a dedicated image processing system, and converted into a digitized signal according to pixel distribution, brightness, color, and the like, and the image system performs various operations on the signals. Extracting the characteristics of the target, and then controlling the action of the device on the spot according to the result of the discrimination, is invaluable in measuring the defect and preventing the defective product from being delivered to the consumer.
现有技术中的视觉成像测量系统具有一定程度上的不足:首先,现有技术中只能通过对待测物摄取图片来测量待测物的平面尺寸,而对于具有一定高度差的尺寸特征的测量,例如对于具有一定深度的孔、凹槽、斜面,或者具有一定高度的凸起物的测量,并没有比较有效的解决方案;其次,由于测量环境的温度变化造成某些高精度待测物表面上的尺寸特征的细小变化通常需要与温度一起测量,从而能够得到温度变化对于尺寸特征变化影响的趋势及规律,现有技术中要实现这个功能还需要进一步完善;对待测物的装夹或者压紧过程需要人工辅助操作的步骤多、自动化程度低,从而导致整个测量过程耗费时间过长,且测量不精确。 The visual imaging measurement system in the prior art has a certain degree of deficiencies: First, in the prior art, the plane size of the object to be tested can be measured only by taking pictures of the object to be measured, and the measurement of the size characteristics with a certain height difference can be measured. For example, for a hole with a certain depth, a groove, a slope, or a projection with a certain height, there is no effective solution; secondly, some high-precision object surface is caused by the temperature change of the measurement environment. Small changes in the size characteristics of the upper part usually need to be measured together with the temperature, so that the trend and the law of the influence of the temperature change on the dimensional characteristic change can be obtained. In the prior art, the function needs to be further improved; the clamping or pressing of the object to be tested The tight process requires many manual steps and low automation, which leads to the entire measurement process taking too long and the measurement is not accurate.
