Field of the Invention The present invention relates to a mechanical arm, and more particularly to a method of positioning a mechanical arm. [Prior Art] In the conventional detection technique, doctors need to obtain a two-dimensional slice image (such as a two-dimensional slice image obtained by computerized tomography or magnetic resonance imaging) obtained by image inspection. Imagine the location of the target. Power | The advancement of technology from the Wf layer sweeper (C〇mputer t〇m〇graphy), and the innovation of image processing technology, enabling two-dimensional slice images provided by professional image processing (2)〇 Slice image) is more and more accurate, and through the improvement of 3D reconstruction and computer graphics technology, these two-dimensional slice images can be combined into three, quasi-cardiac image data, so doctors can This 3D image data is used to understand the position of the target f in the skull. However, this kind of 3D image data can only represent the position of the target with its own standard system. Therefore, the relative position of the doctor in surgery or teaching, and the surgical machine and the target can still be evaluated only by experience, but cannot be accurate. Learned. SUMMARY OF THE INVENTION A positioning method is based on the position of the device. A positioning method, which comprises an aspect of the present invention, is to provide a method for allowing a user to know a target object relative to surgery. According to an embodiment of the present invention, a 200845944 step is presented: firstly, a target is built on the skull in the skull. The location. Then, 枓, to provide the target # mu Λ Λ mechanical arm to move the surgical instrument, so that the surgery is an insane close to the skull. Then, the device is detected together to provide surface image data. Finally, the second surface is provided to provide the position of the target relative to the surgical instrument. Another aspect of the month is the provision of a positioning device that provides the position of the target relative to the surgical instrument. 〃 ^The other embodiment of the present invention - the actual device is composed of a system, a group, a robot arm, a detection module and a stacking module. In the 1st, the inspection module is used to create a three-dimensional image of the skull to provide the purpose, the object: the position of the skull: The robotic arm is used to move the surgical instrument so that the surgical device is close to the skull. The debt test module is used to detect the surface of the head and the surgical instrument to provide surface image data. The overlay module is used to overlay 3D image data and surface image data to provide the position of the target relative to the instrument. The invention thus, the positioning method and apparatus thereof, allows the physician or user to know the position of the target relative to the surgical instrument without empirical guessing. In addition, since the position of the target relative to the surgical instrument can be immediately known, it is no longer just a dream to automate the operation with a robotic arm. BRIEF DESCRIPTION OF THE DRAWINGS The spirit and scope of the present invention will be apparent from the following description of the embodiments of the invention. It does not depart from the spirit and scope of the invention ^ 200845944. Flow =: Figure U corpse / Γ not a kind of positioning method, first, the head #fr _ throwing it can include the following steps: position (step 110). Next, use the _ 车 徒 徒 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目), the position of the surgical instrument can be =!:: The image is represented by the physical coordinates, and then the 3D image data and material are superimposed to provide the position of the target on the physical coordinates (the cow's shirt is like a shell). Because the position of the surgical instrument and the target: step:; mouth = the position of the object relative to the surgical instrument will be known. Moreover, the body § brother 'user can install the ball in step 13 mechanically, and this The circle is so useful in surgery that the user can click on the tip of the surgical instrument. m The position of the instrument tip on the physical coordinate, and the subsequent can be the tip of the hand instrument as a reference point. For example, in a superimposed 3D image 2 After the surface image data, the user will be able to accurately know the position of the target relative to the tip of the surgical instrument. According to the above, the positioning method of the embodiment allows the doctor or the user to know the target and cry with respect to the hand.沾7班了瓦于术The position, without the need to guess by experience. In addition, because the position of the target relative to the surgical instrument can be immediately known, the automatic completion of the operation with the robotic arm will no longer be just a dream, and will describe in detail how to guide the operation with a robotic arm. From the device to the target. 200845944, according to the second ®, the reading of the present invention - the actual process of guiding the surgical device to the target object ^ as shown in the figure, the position of the device on the mechanical coordinate of the mechanical arm ( The steps are called. More, 'this—(4) can determine the position of the surgery (4) on the mechanical arm. 15G can be achieved according to the internal modeling group of the robot arm, the user is only installed on the robot arm, and the internal modeling group is executed. The function t then 'determines the position of the object on the mechanical coordinate according to the position of the target relative to the surgical instrument (step (10)). Referring to Fig. 3, the vector diagram between the coordinates of the New Zealand and the mechanical coordinate. After the dimension image 105 and the surface image data 103 are superimposed, the target object p and the hand: the tip T of the machine should be represented by the physical coordinate N of the surface image (4) itself. In Fig. 3, NP is the position vector of the target p on the physical coordinate N, and the vector NT is the tip of the surgical instrument, the position vector on the target N. On the other hand, the tip of the surgical instrument τ: the mechanical machine that can be mechanically The coordinate R indicates that, for example, the vector RT of Fig. 3 represents the position vector of the tip T of the surgical instrument on the mechanical coordinate R. Thus, the position vector of the target P on the mechanical coordinate R can be known as: RP=NP-NT+RT................................................ According to Fig. 2, the position of the entry point on the mechanical coordinate can be determined after the step and the step 16 (step 170). Of course, the step 17 can also be carried out before the step 15 and the step 16〇. Wherein, the above entry point is recorded on the skull, and in the following step, the surgical instrument will pass through the entry point drill 200845944: directly into, the coordinate wheel enters the mechanical arm end and touches into: set on the skull, and then reuse The sharp position of the surgical instrument can be selected by the user to adjust the surgical device to adjust the length of the surgical instrument: the length direction of the surgical instrument, and the connection point to the target. μ: Specifically, the user can first mechanically Arm work

In the present embodiment, the robot arm 32 is implemented by bribing the LR Mate 2_B small backlash type six-axis robot arm, but this does not limit the present invention. Those skilled in the art may also select other suitable devices instead. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and retouched without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
