In order to be clearly captured the knee of people, taking module 110 can be adjusted the acquisition parameters of capture apparatus by operating desk or remote control
Whole the second acquisition parameters determined for control module 120, such as, camera site can be moved to by support directly over knee,
Shooting angle can be adjusted to vertical with knee, and shooting focal length can be increased to 4 times, and screening-mode can be adjusted to HDR patterns.
In another example it is 1 times to include the shooting focal length corresponding to first image in region to be scanned, control module 120 can determine
Two shooting focal lengths are 5 times.
530, Scan orientation equipment 100 can be according to the second shooting image of parameter acquiring second.The second shooting ginseng
Number can be one or more groups of acquisition parameters.The acquisition parameters can include the position of capture apparatus, shooting angle, focal length,
Screening-mode etc..In certain embodiments, processing module 130 can determine that the second image includes region to be scanned by analysis,
It can be used for setting follow-up sweep parameter.In certain embodiments, second image can be the image warp of multiple angles
Obtained area image to be scanned is crossed after processing.The area image to be scanned can be threedimensional model, 3-D view, infrared figure
As etc..In certain embodiments, second image can be implementing monitoring image or a frame or multiframe in video recording.Described one
Frame or multiframe can be and the preferable image of Region Matching to be scanned.For example, processing module 130 can be by comparing the second figure
Picture and reference picture, so that it is determined that the frame or image that are matched with reference picture.The reference picture can be one or more marks
Quasi- human body image.Standardized human body's image can be obtained by memory module 150.In certain embodiments, second figure
Specified in the image that picture can be obtained by expert or staff according to treatment plan and/or experience from taking module 110.
540, Scan orientation equipment 100 can determine sweep parameter according to the second image.The sweep parameter can wrap
Include the original position of scanning, scanning range, scanning dose, sweep time etc..In certain embodiments, Scan orientation equipment 100
In processing module 130 sweep parameter can be determined according to the second image.For example, processing module 130 can be according to the second image
In region to be scanned position determine scanning original position.In another example processing module 130 can be waited to sweep according in the second image
Retouch the size in region and property determines scanning range, scanning dose, and/or sweep time.In certain embodiments, Scan orientation
Equipment 100 can be scanned according to identified sweep parameter to object to be scanned.
When the first image is unsatisfactory for requiring, acquisition parameters can be adjusted, so that it is determined that the second acquisition parameters, obtain second
Image, the second figure is used to determine sweep parameter.When the second image still is unsatisfactory for requiring, the rest may be inferred, can also basis
Second Image Adjusting acquisition parameters, the 3rd image is obtained, sweep parameter is determined with the last image for meeting to require, so as to realize
Accurate scanning.
, only for convenience of description, can not be it should be noted that above-mentioned for a kind of description of Scan orientation method 500
The application is limited within the scope of illustrated embodiment.It is appreciated that for those skilled in the art, understanding the equipment
Operation principle after, modules may be combined in the case of without departing substantially from this principle, or form subsystem
System is connected with other modules, makees various modifications and variations in the form and details to implementing the said equipment.If for example, the second image
Pass through the analysis of processing module 130, it is impossible to be used in determine sweep parameter, Scan orientation equipment 100 can be true according to the second image
Fixed 3rd sweep parameter, constantly repeats 520 and 530.Such deformation, within the protection domain of the application.
