Problems solved by technology

[0005] In order to solve the technical problem that the existing portable X-ray machines cannot be used in non-standard field environments to obtain qualified X-ray films, this application provides a dynamic photogrammetry system based on X-ray machine detectors, which consists of X-ray machines that are independent of each other and can communicate with each other. At the same time, by setting coded and identifiable marking points and marking lines on the detector and an attitude sensor used to obtain the attitude of the detector, a dual sensor for capturing the marking points and marking lines is set on the X-ray machine. Eye camera unit, so that the display unit on the X-ray machine can display the actual position of the detector in real time, and intuitively display the angle and displacement that need to be corrected when the detector aligns with the X-ray machine

Embodiment 1

[0125] combined with figure 1 and 2 As shown, the dynamic photogrammetry system based on the X-ray machine detector provided in this embodiment is used to dynamically track and capture the actual position of the detector in real time in a static or moving state, so as to quickly align the actual position of the detector with the X-ray machine, Reach the preset transillumination state and obtain qualified X-ray films at one time, including:

[0126] An X-ray machine for emitting X-rays to illuminate the target object and a detector for detecting and imaging the X-rays absorbed by the target object from the X-ray machine;

[0127] Marking points 1, 2, 3, and 4 are sequentially set on the detector near the four corners, any one of the marking points is marked with decoding information for unique identification, and a marking line is set between two adjacent marking points, and A first attitude sensor built into the detector for collecting the attitude information of the detecto...

Embodiment 2

[0137] In order to make full use of the dynamic photogrammetry positioning system provided in Embodiment 1, this embodiment will describe in detail the steps specifically included in the dynamic photogrammetry method based on the X-ray machine detector provided by the dynamic photogrammetry positioning system. Combined with the manual image 3 Instructions include the following steps:

[0138] Step ST100, the X-ray machine is installed in place, the detector is placed in the effective transillumination range of the X-ray machine and any mark point 1, 2, 3, 4 on the detector can be captured by the binocular camera unit on the X-ray machine , identify, and complete the coordinate initialization, establish a world coordinate system centered on the binocular camera unit, which is recorded as the Camera system, specifically as Figure 9 shown;

[0139] Step ST200, move the X-ray machine and / or the detector so that the detector and the target object enter the transillumination ran...

Embodiment 3

[0146] This embodiment specifically provides an optimal method that can satisfy the coordinate initialization mentioned in step ST100 in Embodiment 2, combined with the Figure 4 Shown, specifically through the following methods:

[0147] Step ST110, judging whether there is position information of the marker point 5 , if it exists, execute step ST130, if not, execute step ST120;

[0148] Step ST120, pull out the auxiliary positioning bar in the detector to the calibration position, the binocular camera unit captures and recognizes the marking points 1, 2, 3, 4 and the marking line, and judges whether the marking points 1, 2, 3, 4 are all Recognize, if all have been recognized, then execute step ST140; if not recognized or partially recognized, then adjust the position of the detector, repeat this step until all are recognized, and save the position information of the marker point 5 ;

[0149] Step ST130, identify marking points 1, 2, 3, 4 and marking lines, and judge whe...

Abstract

The invention discloses a dynamic photogrammetry system and method based on an X-ray machine detector. The system is used for dynamically tracking and capturing the actual position of the detector inreal time in a static or moving state so as to quickly align the actual position of the detector with an X-ray machine, achieve a preset transillumination state, and obtain a qualified X-ray film at atime. Meanwhile, the invention further provides a measuring method based on the system, real-time tracking display of a plurality of mark points which are arranged on the detector and used for positioning the spatial position of the detector is achieved through cooperation of a binocular camera shooting unit in the X-ray machine and a unique algorithm, and therefore sighting is rapidly achieved.Through real-time feedback of mutual spatial positions of the X-ray machine and the detector, the alignment state and the imaging distance can be mastered in real time, so that rapid, efficient, convenient and accurate accurate transillumination of the target object is realized, and the problem that an ideal X-ray film can be obtained by multiple transilluminations due to the fact that factors such as the accurate position and angle of a detector cannot be obtained in the prior art is avoided.

Description

technical field [0001] The invention relates to the field of X-ray machine aiming control systems, in particular to a system and method for dynamic photogrammetry based on X-ray machine detectors, which are used to quickly align a portable X-ray machine with a detector in an outdoor environment. Obtain qualified X-ray films. Background technique [0002] Medical portable X-ray machine is also called medical portable X-ray machine or medical X-ray perspective instrument. This type of X-ray machine is suitable for medical use, mainly used in clinics, township health centers, athlete training departments and school clinics and other departments. Due to its low cost, low X-ray dose (high safety), simple operation, small size, and most of them can be connected to a computer for processing and printing, etc., it meets the equipment gaps of medical institutions that are not enough to accommodate large X-ray equipment, and has received a lot of attention. Favored by the medical in...
