Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0041] If the object to be photographed is in a moving state, the shooting time of different cameras is in order. However, when the existing technology is shooting, due to the inconsistency of the shooting time, the resulting image will be misaligned, making the captured image and the object Do not match, resulting in poor composite image effect.
[0042] In order to solve the above problems, a three-dimensional imaging method based on multi-camera synchronous shoo...

The invention discloses a three-dimensional imaging method and device based on multi-camera synchronous shooting and a shooting system, the method is applied to a control box, and the method comprisesthe following steps: when a shooting instruction of a user is received, searching a first camera from a plurality of cameras; sending the shooting instruction to the first camera through the signal cable, so that the first camera group starts to shoot and triggers to generate a first level change signal, the level change signal is sent to a second camera connected in series, the second camera starts to shoot and triggers to generate a second level change signal, thereby enabling the plurality of cameras to synchronously trigger shooting; and obtaining contour images generated after the multiple cameras analyze and calculate the shot images respectively, obtaining multiple contour images, and synthesizing the multiple contour images into a three-dimensional image. By controlling the plurality of cameras to shoot synchronously, the complete contour image of the surface of the object can be obtained, so that the situation of image dislocation after synthesis is avoided.
Description
technical field [0001] The invention relates to the technical field of imaging and image processing, in particular to a three-dimensional imaging method, device and shooting system based on multi-camera synchronous shooting. Background technique [0002] With the further development of 3D scanning technology and its wide application, it is more and more common in real life to use it for multi-directional scanning of 3D objects, and then use computers to build 3D digital models of objects. Its applications can be seen in the fields of industrial design, machine vision, geomorphological measurement, 3D printing, and medical information. [0003] When shooting a three-dimensional object surface profile image, limited by the angle factor, it is impossible for one camera to completely cover the object's surface. It is necessary to use multiple cameras to shoot synchronously at different angles, and then synthesize the shooting results to form a picture. Complete profile image. ...
