Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a pointing device, and more particularly to a laser pointer and a pointing method thereof. [Prior Art] In the domestic patent application No. 98119994, the inventor of the present invention proposes a ## assisted installation of a solar panel guiding system, which can provide the best installation of the solar panel 3, the degree of H-saki, the whole year or any selection period The maximum output power of the inner sun 1; among other things, it is used to guide the installation angle. The device can be used to avoid the use of the traditional compass or the compass operation to generate human error. Wherein, since the structure of the electronic compass is a pair of mutually orthogonal coils using the induced magnetic flux density and the voltage is measured to measure the direction of the magnetic field, the (4) indicated by the electronic compass is a miscellaneous field and a miscellaneous material. Therefore, the accuracy of the electronic compass is actually affected by the magnetic field strength of the surrounding magnetic field and the natural magnetic interference, especially in the internal circuit of the general electronic product or the electric circuit of the electronic circuit. The electronic compass causes magnetic interference, which is invisible to the naked eye, but it obviously affects the accuracy of positioning or pointing. When the electronic compass is initially used, it is changed by the orthogonal coil at different steering angles, and the magnetic flux should be changed. The voltage value of each coil can not form a magnetic circle with its relative voltage center curve. Therefore, when measuring According to the voltage value; the central angle on the magnetic circle determines the steering angle; when the electronic compass moves to the same geographical position or changes in the surrounding magnetic field environment, the position of the magnetic circle on the voltage coordinate changes, that is, the center of the magnetic circle There will be drift or the shape of the magnetic circle will change. In this way, when the user environment has magnetic interference, if the pointing device cannot inform the user whether the environment has magnetic interference and controls the function of the electronic compass to perform the correction, the positioning or pointing error cannot be avoided. Therefore, the inventor of the present invention is working to improve this error, so that the guiding system can simultaneously monitor and control the electronic compass during the adjustment to the optimal angle so as not to be positioned or pointed to be interfered by the external magnetic field. SUMMARY OF THE INVENTION The main object of the present invention is to provide a laser pointer having the functions of being executable and displayed by a stand-alone or wired computer device, and having the functions of judging and indicating the laser moving path. In order to achieve the above object, the present invention provides a laser pointer having a laser module, an electronic compass wafer, and a programmable chip, the laser mode, and a laser beam; the electronic compass chip Having the same sensing orientation as the projection direction of the laser beam, the electronic compass chip is configured to output one of the orientation data corresponding to the sensing orientation; the programmable wafer is electrically connected to the electronic compass wafer for The orientation data is calculated as one of the above-mentioned mosquitoes (4) comparing 'and generating-driving signals to guide the rayman, the action of the ray' to make the projection direction of the laser beam coincide with the specific azimuth angle. The main purpose is to provide a laser pointer with a correction method and an accurate azimuth pointing function. 4, in order to achieve the above object, the invention provides a method for pointing to a redirector, comprising the steps of: a) connecting with the computer device and emitting a laser beam pointing at an azimuth; b) displaying on a computer device The azimuth angle of the laser beam and the corresponding one of the azimuth data; <0 receiving electricity «sets the azimuth angle and compares with the azimuth angle of the laser beam pointing; d) by algorithm The laser beam is directed to the shortest rotation path of the particular azimuth; and, e) the drive signal is directed to the direction of rotation of the bow laser beam. BRIEF DESCRIPTION OF THE DRAWINGS In order to explain the structure, features and advantages of the present invention in detail, the following description of the preferred embodiments of the present invention r The second figure is a simulation analysis of different operating modes of the electronic compass wafer provided by the above preferred embodiment, wherein the second figure A is a normal mode operating under normal magnetic field environment, and the second figure B is operating in a normal magnetic field environment. In the continuous mode under induction, the second figure C is the correction mode in the abnormal magnetic interference state; ~ the third figure is the instant monitoring state displayed by the laser pointer connected to the computer device provided by the above preferred embodiment; 1352191 The fourth figure shows the operation flow of the laser pointer connected to the computer device provided by the above preferred embodiment. Referring to the first embodiment, as shown in the first preferred embodiment of the present invention, a laser pointer can guide a specific direction according to a specific azimuth angle θ° given by the external computer device 2, The laser pointer 1 includes a laser module 1 , an electronic compass chip 2 , a transmission interface 3 , and a programmable wafer 40 . The laser module 10 is used to project a laser beam. The single-directional visible light can be emitted at the same time as the laser pointer 1 is activated; the mechanical actuation system of the laser module 10 can be, but is not limited to, H or an external mechanical control mode, < computerized The control is connected by a programmable wafer 4 or a computer device 2. The electronic compass wafer 20 senses the direction of the magnetic field by using a pair of mutually orthogonal coils. During the sensing operation, the sensing orientation is determined by the direction in which the wafer 2G is set and the sensed orientation is determined by the earth's magnetic field and the laser. The combination of the pointer itself or the surrounding induced magnetic field is such that the electronic compass wafer 20 provided in the embodiment sets the sensing orientation to be the same as the projection direction of the laser beam, when the electronic chip 2G is controlled After the end group 2〇2 receives the execution instruction, the algorithm developed by the chip 2〇(4) can be used to record the orientation data corresponding to the t-wire reading financial information in a group 2G4(4). Since the magnetic bias, the geomagnetic density and the induced magnetic field of the f-directed ϋ vary from environment to environment, it is necessary to find the location for initial calibration before operating the laser pointer. If you move to other, you need to re-do the initial 6 1352191 Therefore, the electronic compass wafer 20 further has a switching end group 206 electrically connected to a switching element 22, and when the switching element 22 is turned on/off, the switching state is used as a switching instruction for changing the potential of the switching end group 206. 'The electronic compass wafer 20 can be automatically calibrated; the correction is performed by rotating the wafer 20 one turn to obtain the largest and smallest circles or ellipses' to determine the center of the magnetic circle and the induced voltage related parameters. Referring to the second figure, the TDCM3 developed by TOPTEAM TECHNOLOGY CO. LTD is used as the electronic compass wafer 20 provided in this embodiment to perform simulation analysis in different operation modes. Of course, any of the above sensing and operation functions are as described above. The electronic compass wafer can exert the functions of the present invention, and is not limited thereto; the second A to C maps respectively correspond to three operating modes of different magnetic field environments under different control commands (normal mode, continuous mode, and correction mode). The control end group 202 and the switch end group 206 are different in the execution command rtS and the switching command RX. The output end group 204 outputs different orientation data corresponding to the magnetic field environment. The data format of the orientation data is 3 sets of hexadecimal data Status+0MSB +0LSB, where:
