Embodiment 1
[0055] Embodiment 1, a system for rapidly reconstructing a 3D model based on the on-site environment, includes: a 720° camera, a 360° camera, and a core processing device.
[0056] Such as figure 1 As shown, the number of the 720° camera is one, which is set in the center of the scene environment. The 720° camera is composed of 6 CCDs, and the 6 CCDs are respectively located on the top, bottom, left, right, front, and back of the 720° camera. Among them, the four CCDs on the horizontal plane can capture the entire 360° space parallel to the horizontal plane, and the four CCDs on the vertical plane can capture the entire 360° space parallel to the vertical plane. There are four 360° cameras in total, and the four 360° cameras are symmetrically arranged around the scene environment. Both the 720° camera and the 360° camera communicate with the core processing device through a wireless / wired network.
[0057] The core processing device stores a factory planning CAD drawing, wh...
Embodiment 2
[0058] Embodiment two, such as figure 2 As shown, the method for quickly reconstructing a 3D model based on the on-site environment includes steps:
[0059] S101. Trigger the 720° camera and the 360° camera to take real-time pictures of the on-site environment, and obtain real-time pictures of the on-site environment including equipment.
[0060] In this step, also include:
[0061] A. Use the SIFT algorithm to splice the sub-pictures captured by the 6 CCDs in the 720° camera into a panoramic picture.
[0062] B. Splicing the sub-pictures captured by all 360° cameras with the above-mentioned panoramic pictures using the SIFT algorithm to form a real-time picture.
[0063] When the 720° camera and the 360° camera receive the shooting command, they enter the shooting mode and shoot the scene environment. The 6 CCDs of the 720° camera shoot the scene environment at the same time to obtain 6 sub-pictures, and the 4 360° cameras also shoot the scene environment at the same time...
