Embodiment 1

[0029] figure 1 It is a schematic flow chart of a positioning method provided by Embodiment 1 of the present invention. This embodiment is applicable to determining the moving distance of the hospital bed in various directions when it moves from the current position to the target position. This method can be performed by a positioning device. Execution, the apparatus may be implemented in the form of software and / or hardware, and optionally, executed by a server or an application program in the server.

[0030] Such as figure 1 Described, the method of the present embodiment comprises:

[0031] S110. Collect image information of the object to be scanned based on a preset photographing device, and acquire key points corresponding to the object to be scanned in the image information.

[0032] Among them, see figure 2 , the photographing device 210 may be a camera, and the camera may be a monocular camera, a binocular camera, etc., and the user may set it according to the act...

Embodiment 2

[0051] Before determining the moving distance of the key point along at least one direction through the positioning parameter, the positioning parameter related to the movement of the key point may be determined. It should be noted that the key point and the hospital bed are relatively static, so determining the target moving distance of the key point is equivalent to determining the target moving distance of the hospital bed. image 3 It is a schematic flow chart of determining the positioning parameters provided by Embodiment 2 of the present invention.

[0052] Such as image 3 As mentioned, the method for determining the positioning parameters includes:

[0053] S310. Mark at least two original reference points on the original reference object in advance, and determine a horizontal movement reference distance and a vertical movement reference distance from the at least two original reference points to the target position.

[0054] Wherein, the original reference object c...

Embodiment 3

[0079] Figure 4 It is a schematic structural diagram of a positioning device provided by Embodiment 3 of the present invention. The device is configured in a scanning imaging device and includes: a key point acquisition module 410 , a target pixel coordinate determination module 420 and a target moving distance determination module 430 .

[0080] Among them, the key point acquisition module 410 is used to collect the image information of the object to be scanned based on the preset shooting device, and obtain the key points corresponding to the object to be scanned in the image information; The correcting parameters correct the initial pixel coordinates corresponding to the key points to obtain the target pixel coordinates corresponding to the key points; the determination target moving distance module 430 is used to determine the key points along at least one The direction moves to the target moving distance of the target position; wherein, the optical axis of the shooting d...

Abstract

An embodiment of the invention discloses a placement method, a device, a server and a storage medium, wherein the method comprises the steps of acquiring image information of a to-be-scanned object based on a preset photographing device, and acquiring a key point which corresponds with the to-be-scanned object in the image information; correcting the initial pixel coordinate which corresponds withthe key point according to a correction parameter, and obtaining a target pixel coordinate which corresponds with the key point; and according to the target coordinate pixel and a placement parameter, determining a target movement distance between the key point and a target position. The placement method, the device, the server and the storage medium settle a problem of tedious and complicated calculation caused by utilizing a series of coordinates for calculating the movement distance of a ward bed in each direction in prior art, and realize technical effects of quick, simple and accurate determining of the target movement distance of the ward bed in each direction and automatic placement according to the target distance.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical technology, and in particular, to a positioning method, device, server and storage medium. Background technique [0002] In the prior art, the image inspection process in a hospital is generally as follows: after the user registers information and enters the scanning room, the user lies on the hospital bed and positions himself under the guidance of the technician. The technician moves the bed to set up the position, and after the set-up is completed, the scan starts. [0003] Among them, moving the bed and positioning is a very important and indispensable operation, mainly the technician realizes the positioning of the hospital bed by controlling the relevant buttons in the operating room or scanning room. In the process of operation, there is manual participation, and there is a certain deviation in the position of the hospital bed due to human error, which leads to the technica...
