The invention provides a tunnel construction area three-dimensional model construction method and system. The tunnel construction area three-dimensional model construction method comprises the steps that three-dimensional laser point cloud data and a plurality of two-dimensional images of a tunnel construction area are coaxially obtained, and all the two-dimensional images can be spliced into a tunnel construction area panorama; and spherical projection is performed on all the two-dimensional images, RGB information of pixel points in the two-dimensional images is directly given to three-dimensional laser point cloud data of the same angle, all the two-dimensional images are directly spliced, and a three-dimensional model of the tunnel construction area is constructed. 本发明提供了一种隧道施工区域三维模型构建方法及系统。其中，一种隧道施工区域三维模型构建方法，包括：共轴获取隧道施工区域的三维激光点云数据及若干个二维图像，所有二维图像可拼接成隧道施工区域全景图；将所有二维图像进行球面投影，同时将二维图像中像素点的RGB信息直接赋予至相同角度的三维激光点云数据处，直接拼接所有二维图像，构建出隧道施工区域三维模型。
