Embodiment

[0046] The processing flow of a wireless transmission control method for a three-dimensional scanner of the present invention is shown in figure 1 , the processing steps are as follows:

[0047] In the first step, the wireless transmission mode is deployed in the 3D scanner and the workstation. After the workstation and the 3D scanner establish a wireless network, the workstation sends a start scanning command and goes to the second step.

[0048] In the second step, the 3D scanner starts to collect information, and sets the priority of sending information according to the type of information. Small quantity. Therefore, this wireless transmission control method is applied to the data transmission from the 3D scanner to the workstation. Control messages are sent as high-priority messages and cannot be filtered. The data volume of location data and image summary message is not large, and the filtering operation is not performed when the transmission is blocked, and the filter...

Abstract

The invention provides a wireless transmission control method, system and device of a three-dimensional scanner and a medium. The current information transmission condition is detected by analyzing the information transmission of the three-dimensional scanner and a work station within a period of time, and when it is detected that the information transmission is unstable or the transmission speed is insufficient, a sending strategy is dynamically adjusted in real time according to information transmission conditions, priorities of control information, position information, image information and image summary information are set, important information is preferentially transmitted according to the priorities, quality evaluation standards are dynamically adjusted according to the image summary information, and high-quality image frames in the image information are transmitted. According to the invention, the transmission data volume is actively controlled, and the delay is reduced, so that a smoother scanning effect under the current network condition is realized.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a wireless transmission control method, system, device and medium of a three-dimensional scanner. Background technique [0002] The existing close-range photogrammetry method needs to establish a connection between the 3D scanner and the workstation for communication. The scanner collects real-time position data and image data and transmits them to the workstation. The workstation controls the scanner and calculates the received position data and image data to obtain the three-dimensional point coordinates of the object. [0003] Most of the existing 3D scanners are connected and work through wired methods, such as USB cable or wired network, connected with workstations, real-time transmission of image data, position data and receiving workstation control instructions. This wired connection method will cause a lot of inconvenience in actual use. For example, in the fa...
