Embodiment 1

[0056] The present invention provides a virtual surgery simulation method, which can be applied to a device, and the present invention does not limit the specific equipment of the device.

[0057] Such as figure 1 As shown, the main flow of the information processing method is described as follows:

[0058] Step S101: Determine the corresponding virtual hand model according to the pre-acquired three-dimensional information of the virtual operator's hand;

[0059] Step S102: displaying a virtual space for virtual surgery and establishing a coordinate system associated with the virtual space, the virtual space includes a virtual surgical instrument model, a virtual human tissue model as a virtual surgical object, and a virtual hand model;

[0060] Step S103: During the implementation of the virtual surgery, collect the 3D information of the hand in real time, and recognize the gestures of the virtual surgical operator based on the 3D information of the hand, as well as the posi...

Embodiment 2

[0069] Based on the same inventive concept as the virtual surgery simulation method in Embodiment 1 of the present invention, the virtual surgery simulation method in Embodiment 2 of the present invention includes:

[0070] Further, the three-dimensional information of the hand of the virtual surgical operator is collected in real time through the depth detection method based on the time of flight. The time-of-flight ranging method belongs to the two-way ranging technology, which mainly uses the flight time of the signal to and fro between two asynchronous transceivers or reflected surfaces to measure the distance between nodes. In the virtual surgery simulation system, the information is collected through time-of-flight-based depth detection. Specifically, it is necessary to collect real-time three-dimensional information of the virtual surgical operator's hand. The hand includes every bone and joint of the fingers as well as the palm and wrist etc.

[0071] Further, the two...

Embodiment 3

[0085] Based on the same inventive concept as the virtual surgery simulation method in the first embodiment of the present invention, the embodiment of the present invention provides a device, please refer to Figure 6 , the device includes:

[0086] The preprocessing module 201 is configured to determine the corresponding virtual hand model according to the pre-acquired three-dimensional information of the hand of the virtual surgery operator, and display the virtual space for performing the virtual surgery and establish coordinates associated with the virtual space system, the virtual space includes a virtual surgical instrument model, a virtual human tissue model as the virtual surgical object, and the virtual hand model;

[0087] The information collection and recognition module 202 is configured to collect the three-dimensional information of the hand in real time during the implementation of the virtual surgery, and recognize the gestures of the virtual surgery operator ...

Abstract

The invention discloses a virtual operation simulation method and device, electronic equipment and a storage medium, and the method comprises the steps: determining a corresponding virtual hand model according to the pre-collected hand three-dimensional information of a virtual operation operator; displaying a virtual space and establishing a coordinate system, wherein the virtual space comprises a virtual surgical instrument model, a virtual human body tissue model and a virtual hand model; collecting hand three-dimensional information in real time to identify the gesture of a virtual operation operator and the position relationship among the virtual operation instrument model, the virtual human body tissue model and the virtual hand model; and determining an instruction and an operation action of a virtual operation operator based on the gesture and the position relationship so as to synchronously display a virtual picture of the virtual operation. According to the technical scheme provided by the invention, the technical problem that the gesture of a virtual operation operator can be associated with the virtual hand model on the display only by depending on wearable equipment such as information input equipment or data gloves and the like during the virtual operation in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a virtual surgery simulation method, device, electronic equipment and storage medium. Background technique [0002] The development of science and technology has driven the progress of society, and emerging technologies have been applied to the medical field, which has had a huge impact on the medical industry.
