The working principle of the simple three-dimensional imaging device based on line structured light is as follows:
when scanning some centrosymmetric structures, such as a cup similar to a cylinder and a vase similar to a cone, a complex or high-precision scanner is not needed when scanning such objects.
In this example, a line laser is emitted from the line laser 41 to irradiate the surface of the object, and the irradiation angle of the laser is at an angle to the capturing angle of the high-definition camera 22, so that the outline of the irradiated portion can be displayed. When the plane where the emitted linear laser is located is perpendicular to the object placing platform and just passes through the central axis of the object, at the moment, the external contour of the object can be obtained only by scanning one frame, and then a corresponding three-dimensional image is generated in an image processing module of the computer. When laser irradiates the surface of an object, a continuous line is formed on the surface of the object, the line represents the outline of the irradiated object, the high-definition camera 22 shoots the outline, the distance from the outline to the axis is calculated, and the outline is rotated according to the distance, so that the three-dimensional graph of the object can be obtained in a computer.
In connection with the example of fig. 3, the object a is placed on the placing table 52, and the axis C of the object a coincides with the axis of the placing table 52, so that the line laser 41 moves circumferentially about the axis C. The laser emitted by the line laser 41 is projected on the surface of the object A, and when the high-definition camera shoots, a line B is formed. When the line laser is rotated to the viewing angle position perpendicular to fig. 3, the obtained line is the maximum profile of the object, and the maximum profile rotates around the axis C to obtain the three-dimensional figure of the object a.
Of course, the object is not necessarily placed exactly in the center of the placement platform, and the laser does not necessarily pass through the central axis of the object. At this time, the operation of the electric ring rail 31 is controlled by the control circuit, so that the line laser 41 runs around the electric ring rail 31, and the line laser 41 irradiates the object placed on the placing platform and then moves circularly. In this way, each frame of the object contour within the camera range can be obtained, the contour of each frame is discretized into points, and the points are generated in the image processing module of the computer to form a three-dimensional image. In addition, two outlines of the laser right perpendicular to the shooting surface of the camera are found out and rotated in the image processing module to generate a three-dimensional image. And compared with images obtained from other frames to verify the accuracy of the generated images.
The scanning is carried out in the environment covered by the light shield, so that the influence of an external light source is avoided. The accuracy of the scanned image is high. And taking the light shield away, shooting the color of the surface of the object, and extracting and filling the color into the three-dimensional image.
The three-dimensional imaging device is particularly suitable for objects with single color patterns and simpler color patterns, and the central symmetry of the objects is high. Meanwhile, the simple three-dimensional imaging device based on the line structured light is low in scanning workload and simple in component, so that scanning imaging is easy and fast, cost is low, and the simple three-dimensional imaging device is very suitable for families to use.
