Problems solved by technology
[0003] Today's 3D inspection devices cannot perform synchronous splicing of image data when imaging through cameras, resulting in jagged gaps on the surface of the workpiece model during 3D imaging, and complex curved surfaces such as deep holes, grooves, and reflective surfaces. When testing, it cannot be well reflected in the workpiece model through the lightness and darkness of the color, which affects the accuracy of the workpiece model

The invention relates to the technical field of three-dimensional detection, in particular to a three-dimensional detection device based on structured light, which comprises a storage platform, a to-be-detected workpiece, a structured light source, a camera and an information processing unit, the structured light source comprises a plurality of light source modules, and an image data collection unit for collecting graphic data is arranged in the camera, an image data output unit for transmitting image data is arranged in the camera; according to the invention, the image data collection unit and the image data output unit are arranged to transmit the image information collected by the cameras to the information processing unit, and the data synchronization unit is used to intelligently splice the image data transmitted by the two cameras, so that a zigzag connection gap is prevented from occurring during later imaging, image data are converted through the image data conversion unit, deep holes, grooves and the like in the workpiece to be measured, complex curved surfaces and reflective surfaces are reflected in the three-dimensional model by adjusting colors and brightness, and the accuracy degree of the three-dimensional model is improved.
Description
technical field [0001] The invention relates to the technical field of three-dimensional detection, in particular to a three-dimensional detection device based on structured light. Background technique [0002] Three-dimensional data measurement technology is an important topic in the field of computer vision, and has a wide range of applications in virtual reality, cultural relic protection, machining, film and television special effects production, computer simulation, clothing design and other fields. Three-dimensional data measurement is to measure the three-dimensional data of the object. According to the principle or medium used in three-dimensional data measurement, it can be divided into two categories: contact measurement and non-contact measurement. Contact measurement is a measurement method that is in contact with the measured object during measurement; non-contact measurement refers to a measurement method that is not in contact with the measured object during m...
