The invention relates to the field of visual inspection, in particular to a flying camera visual imaging detection system and method for detecting large-sized objects, wherein the detection system includes a carrying platform for placing a test piece, and an imaging unit communicatively connected with a control unit; its features In that: it also includes a motion unit communicated with the control unit; the imaging unit includes a light source module and an area array camera module controlled by a strobe controller; the surface to be detected that is compatible with the optical detection angle on the test piece corresponds to an imaging The optical detection mode of the unit; the motion unit is used to move the imaging unit and adjust the imaging unit to the corresponding optical detection mode; it also includes an image processing and AI algorithm unit communicated with the control unit. The invention keeps the measured object static, and realizes flying shooting by controlling the movement of the area array camera, thereby not only solving the problem of the complexity of the optical imaging system, but also effectively improving the efficiency and accuracy of detecting large-sized objects.
Description
technical field [0001] The invention relates to the field of visual detection, in particular to a flying-shooting visual imaging detection system and method for detecting large-sized objects. Background technique [0002] As a new type of high-efficiency machine vision technology, flying camera realizes uninterrupted imaging of the object to be tested through the relative movement between the vision system and the object to be tested, which greatly reduces the time consumed by detection. Therefore, in industries pursuing fast production tempo, There are broad application prospects. [0003] At present, the realization of flying shooting technology is mostly by controlling the movement of the object to be measured, while the camera responsible for visual perception remains static, so as to ensure stable and accurate imaging quality in the whole field of view. For the detection of small-sized parts, this method saves the visual space of the organization and the optical design...
