the first processor and the second processor establish WebRTC connection;
the second display terminal and the first display terminal synchronously display the pathological image information, and when the picture on the first display terminal generates first label information, the first label information is synchronously displayed on the second display terminal; and when the picture on the second display terminal generates second annotation information, the second annotation information is synchronously displayed on the first display terminal.
In combination with a specific application scenario, in implementation, the first processor and the first display terminal are connected with an image acquisition device on a microscope, and receive and display a pathological image of a solid section currently located under the microscope on the first display terminal. The method comprises the steps that a main control party (a first processor) and an invited party (a second processor) establish WebRTC connection, firstly, the main control party generates a consultation link, the consultation link is sent to communication software of the invited party, such as QQ and WeChat, the invited party, namely the invited party, finishes connection with the main control party by clicking the consultation link or pasting the consultation link to a computer browser, and at the moment, the same picture as that on a first display terminal of the main control party is displayed on a display picture of the invited party, namely sharing of pathological section images under a microscope is realized. After the consultation link is established, the main control party and the invited party can carry out voice implementation, and pictures on the display terminal can be labeled, so that both sides of the labeled contents can see. The first processor further performs AI intelligent diagnosis on the received pathological image information, identifies suspicious information on the pathological image information, automatically marks out suspicious regions on the pathological image information, displays the suspicious regions on the first display terminal and the second display terminal, and can be seen by operators positioned in front of the first display terminal and the second display terminal, as shown in fig. 3. If a party participating in the method is confused about a certain area, the method can also be used for drawing on the display terminal, other parties can also see the drawing area, and the parties can also manually clear the drawing lines.
When someone adjusts the microscope, the pathological image information changes, and the display pictures of the master control party and the invited party also change, that is, the pictures on the first display terminal and the second display terminal change synchronously, and the information marked on the last display picture also disappears. At the moment, the first processor records the change track of the pathological image information and presents the change track on the first display terminal and the second display terminal. The first processor and the second processor can also realize a mute operation, and if the environment of the invited party is noisy, other consultation doctors cannot be influenced after the mute operation, and a quiet consultation environment is kept.
