Embodiment 1
[0064] figure 1 It is a flowchart of a method for determining the measurement position of a virtual ruler provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of determining the measurement position of a virtual ruler on a measured wall surface. The device for determining the measurement position of the ruler is performed by means of software and / or hardware. The device can be configured in a terminal device. Exemplarily, the terminal device can be a smart phone, a tablet computer, a notebook computer or a desktop machine and other smart devices. Specifically include the following steps:
[0065] S110. Obtain the point cloud data of the measured wall, and judge the attribute of the measured wall based on the point cloud data of the measured wall.
[0066] Wherein, for example, the point cloud data of the measured wall is collected based on a three-dimensional laser scanner, and the point cloud data refers to a collection of point ...
Embodiment 2
[0090] image 3 It is a flow chart of a method for determining the measurement position of a virtual ruler provided in Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above embodiments. Optionally, determining the measurement position of the virtual ruler on the target wall based on the point cloud data of the target wall and the ruler placement rule includes: based on the points of the target wall The cloud data determines the size of the target wall; matches the size of the target wall with at least one preset size range, and determines the ruler placement corresponding to the target wall based on the successfully matched preset size range Rules; wherein, the preset size interval includes a preset height interval and / or a preset width interval; according to the ruler placement rule corresponding to the target wall and the point cloud data of the target wall, determine the The measurement position of the v...
Embodiment 3
[0109] Figure 4 It is a flow chart of a method for determining the measurement position of a virtual ruler provided in Embodiment 3 of the present invention. The technical solution of this embodiment is further refined on the basis of the foregoing embodiments. Optionally, the determining the measurement position of the virtual ruler on the target wall according to the rule of placing the ruler corresponding to the target wall and the point cloud data of the target wall includes: Determine the width of the target wall and the boundary coordinates of any boundary along the vertical direction according to the point cloud data of the target wall; based on the width of the target wall, the boundary coordinates and the relationship with the target The position coordinate function in the ruler placement rule corresponding to the wall determines the measurement position of the center point of the virtual ruler on the target wall.
