An intelligent scanning online measurement system and measurement method based on image recognition

Abstract

The invention discloses an intelligent scanning online measurement system based on image identification, wherein the system relates to the field of industrial automation. The intelligent scanning online measurement system comprises an image identification positioning module, a six-freedom robot laser scanning measurement module and a measurement control module, wherein the image identification positioning module comprises a CCD camera triggering switch, a CCD camera, a CCD camera bracket, and a CCD camera electronic control unit (ECU). The measurement control module comprises a central processing unit, a measurement system controller, a measurement robot pose ECU and a measuring head ECU. The six-freedom robot laser scanning measurement module comprises a six-freedom measurement robot, a measurement robot pose sensor, a measurement robot joint motor, a laser scanning measuring head and a measurement triggering switch. The invention further discloses an intelligent scanning online measurement method based on image identification. The intelligent scanning online measurement method comprises the steps of establishing an intelligent scanning strategy database; performing image identification and initial positioning; performing adaptive scanning measurement; performing accurate secondary positioning in the measurement process; and updating a scanning strategy in the scanning measurement process.

Description

technical field [0001] The invention relates to a scanning on-line measurement method, in particular to an image recognition-based intelligent scanning on-line measurement system and measurement method. Background technique [0002] With the continuous emergence of new sensors and the continuous improvement of non-contact measurement theory, it is possible to use non-contact measurement technology to realize online measurement of free-form surfaces. Compared with traditional sample measurement technology and CMM technology, non-contact laser scanning detection technology has the advantages of non-contact, fast detection speed, large data volume, etc. It has great advantages in reverse engineering, quality inspection, virtual reality and other fields, and is widely used It is applied in production and life. [0003] With the introduction of concepts such as Industry 4.0 and Internet +, mass customization (OEM) production is subverting the same homogeneous products, and facto...

Problems solved by technology

The inspection tool and CMM sampling inspection method needs to make a special inspection tool for each piece to be tested, which not only increases the cost of quality management, but also has low detection efficiency and cannot realize online detection; the online detection method of the key points of the online detection robot, It can only complete the detection of some key points, and cannot meet the overall quality management requirements of the product. Especially for the production of parts, the detection of key points for small parts cannot fully reflect the status of the parts. At the same time, due to the introduction of robot measurement and special CMM measurement The system greatly increases the production cost, which greatly limits the application of robot online detection in parts production
