Description

Visual imaging measuring system with adjustable fill light and automatic loading and unloading

Technical field

Background technique

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.

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, Two kinds of CMOS cameras and CCD cameras, CMOS camera pixels are high, about 25 million pixels, CCD camera pixels are low, about 1.5 million pixels), the target is converted into an image signal, and transmitted to a dedicated image processing system, according to Pixel distribution and brightness, color and other information are converted into digital signals. The image system performs various operations on these signals to extract the features of the target, and then controls the on-site device actions according to the result of the discrimination, and measures the defects and prevents defective products from being distributed. It is immeasurable in terms of the function of the consumer.

The prior art visual imaging measurement system has certain limitations on the measurement of the complex structure shape on the surface and inside of the object to be tested. First, for a small-sized object to be tested having a complicated structure, the ambient light during the measurement process is insufficient. Irradiation on the surface of the object to be tested, especially on the inner surface of the object to be tested, causes the camera to be underexposed or excessively covered during the measurement process, so that the obtained image has poor image quality, thereby causing multiple repeated measurements to obtain a satisfactory measurement result. This undoubtedly greatly reduces the measurement efficiency and increases the measurement cost. Secondly, due to the small size of the complex structure, the object to be tested is difficult to grasp, the process of loading and unloading the measurement object is low, the loading and unloading efficiency is low, and in addition, during the loading and unloading process It is easy to cause damage to the object and increase production costs.
