Embodiment 1

[0055] see figure 1 , figure 2 and image 3 The three-dimensional ultrasonic imaging method based on multi-sensor information fusion proposed in this embodiment specifically includes the following steps:

[0056] Step S101: Use the sensor group to obtain the first pose information of the ultrasonic probe. In this embodiment, the sensor group is set on the ultrasonic probe, and the sensor group includes at least inertial guidance sensors, that is, different types of sensors are set on the ultrasonic probe at the same time. Consider the position and posture of the ultrasound probe from different angles. The application of the above-mentioned sensor group greatly reduces the requirements of the system on the use environment, and does not need to install an external positioning module to locate the attitude of the probe, which can significantly improve the portability of the system.

[0057] What needs to be explained here is that the inertial guidance sensor includes a first ...

Embodiment 2

[0082] see Figure 4 , the present embodiment provides a three-dimensional ultrasonic imaging device based on multi-sensor information fusion including:

[0083] The sensing acquisition module 401 is configured to use the sensor group to obtain the first pose information of the ultrasonic probe, the first pose information is obtained by the sensor group according to the collected linear and angular acceleration information, wherein the sensor group is arranged on the ultrasonic probe, The sensor group includes at least an inertial guidance sensor, and a camera acquisition module 402, configured to use the camera to acquire the second pose information of the ultrasonic probe, and the second pose information is obtained by the camera according to the collected panoramic scene, wherein the camera is set at On the ultrasonic probe, the filtering module 403 is used to obtain the pose information of each frame of the ultrasonic image by using the method of optimal estimation filteri...

Abstract

A multi-sensor information fusion-based three-dimensional ultrasound imaging method, a device and a terminal machine-readable storage medium, the multi-sensor information fusion-based three-dimensional ultrasound imaging method comprising: first, obtaining first posture information of an ultrasonic probe (101) by using a sensor group, the first posture information being obtained by the sensor group according to collected linear and rotational acceleration information, the sensor group being disposed on the ultrasonic probe (101), and the sensor group at least comprising two types of devices, an acceleration sensor and a gyroscope; second, obtaining second posture information of the ultrasonic probe (101) by using cameras (201, 202, 203, 204), the second posture information being obtained by the cameras (201, 202, 203, 204) according to collected panoramic scenes, wherein the cameras (201, 202, 203, 204) are disposed on the ultrasonic probe (101); then, obtaining posture information of each frame of an ultrasonic image by using an optimal estimation filtering method, and reconstructing a three-dimensional image of each frame of the ultrasonic image according to an interpolation method; thus, the combined use of the sensor group and the cameras (201, 202, 203, 204) is achieved on the ultrasonic probe (101), and the quality in three-dimensional ultrasonic imaging technology is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to a three-dimensional ultrasonic imaging method and device based on multi-sensor information fusion. Background technique [0002] In recent years, the application of three-dimensional ultrasound imaging technology has become more and more extensive. The reason is that, compared with traditional two-dimensional images, three-dimensional ultrasound imaging eliminates the need for doctors to synthesize multiple two-dimensional images based on experience to understand their three-dimensional anatomical structures. The value is relatively large, so it has attracted the attention of researchers and medical workers. [0003] At present, the common three-dimensional ultrasound imaging technologies are mainly divided into two categories: the first is the use of three-dimensional electronic phased array and other methods, which can obtain three-dimensional data without moving th...
