The inside cavity of measuring arm 3, be equipped with lofting laser device 100 in the measuring arm 3, lofting laser device 100, include:

processing module 110

The lofting laser device 100 is arranged in the lofting laser device 100, and when the lofting laser device 100 is connected with an external device, the lofting laser device receives a target image 210 sent by the external device in a Bluetooth, infrared, wireless Wifi or other modes, and optionally converts the target image 210 into a readable format for storage. Whether or not conversion is required may depend on the format of the target image 210 that is readable by the lofting laser apparatus 100.

Central control module 120

The transfer component, which is a control command of the lofting laser apparatus 100, is connected to the processing module 110, and receives the target image 210 sent from the processing module 110 or the format file converted from the target image 210, so as to obtain the image desired by the user on the imaging target. After the central control module 120 receives the target image, the target image 210 is converted into a control command to be issued. It is understood that the number of the target images 210 that can be received by the central control module 120 is not limited to one, and the lofting laser apparatus 100 may be fixed at the center of the construction area to project the required images to the periphery during the actual construction process. Therefore, a plurality of target images 210 can be stored in the system and respectively converted into control commands, and switching can be performed according to the requirements of users on different construction surfaces.

Laser source module 140

And the laser source module 140 is connected with the central control module 120 in a communication manner, a control instruction formed by the central control module 120 is issued to the laser source module 140, and the laser source module 140 emits a laser beam according to the control instruction. For the laser source module 140, the control command may be to start/stop emitting the laser beam, or to set the emitted laser beam to a strobe mode based on the start/stop command.

Scanning galvanometer module 160

Fixed facing the laser source module 140, the laser beam emitted from the laser source module 140 is reflected by the scanning galvanometer module 160 until being projected onto the target object 200.

-galvanometer drive module 150

The frequency and the forming shape of the laser beam are determined by the scanning galvanometer module 160, so that a galvanometer driving module 150 is arranged between the central control module 120 and the scanning galvanometer module 160, is in communication connection with the central control module 120, forms a driving command according to the control command sent by the central control module 120, and then sends the driving command to the scanning galvanometer module 160

The mirror module 160, the scanning galvanometer module 160, reflects the laser beam according to the driving command, and finally presents the target image 210. It is understood that the control command sent by the central control module 120 to the galvanometer driving module 150 includes a desired frequency of the laser beam, a shaping shape, and the like. The driving command generated by the galvanometer driving module 150 is a command for controlling the rotation speed, the rotation direction, etc. of the scanning galvanometer module 160.

With the above configuration, a user firstly sends a target image 210 to the lofting laser device 100 through an external device, the processing module 110 in the lofting laser device 100 receives and forwards the target image to the central control module 120, the central control module 120 converts the target image 210 into a control instruction, the laser source module 140 sends a laser beam to the scanning galvanometer module 160 according to the control instruction, and the galvanometer driving module 150 controls the scanning galvanometer module 160 according to the control instruction, and finally the laser beam is projected to the target object 200 through the reflection of the scanning galvanometer module 160 to form the target image 210.

The target image 210 formed on the target object 200 may have various colors and various brightnesses according to different requirements of construction conditions, and therefore, a laser modulation circuit 130 is provided between the central processing module 110 and the laser source module 140, and different modulation modes can be selected according to different measurement requirements. For example, the pulse modulation mode may be selected when the measurement value is calculated based on the time difference of reception of laser emission, and the sinusoidal waveform mode may be selected when the measurement value is calculated based on the phase difference of reception of laser emission. Therefore, the laser modulation module can adjust the laser beam emitted from the laser source module 140 to be converted into a desired form for different required modes.

Meanwhile, the laser source module 140 may use a laser source formed by a single laser diode or a laser source group formed by a plurality of laser diodes according to different working condition requirements. Specifically, the laser source module 140 has a first laser diode 180 therein and has a single wavelength, and the color of the first laser diode 180 can be used to display different patterns or shapes; or the laser source module 140 has a plurality of first laser diodes 180 with different wavelengths, so that more abundant image information can be presented by using a plurality of colors.

In order to control the reflection effect of the scanning galvanometer module 160 on the laser beam more conveniently, more accurately and more rapidly, the scanning galvanometer module 160 includes a reflective mirror MEMS and is disposed on a biaxial electromechanical structure, and the biaxial electromechanical structure is located at the head of the measuring arm for convenient projection. The double-shaft electronic mechanical structure comprises an X plane and a rotating shaft which can rotate around an X axis, so that a part arranged on the X plane can rotate along with the rotation of the X plane around the X axis. And both ends of the rotation axis of the Y plane are rotatably connected to the inside of the X plane.

Specifically, the middle part of the X plane is hollowed out to form a space, the space is reserved for the Y plane to be arranged, and meanwhile, the rotating shaft of the Y plane is connected to the side edge of the space, namely the inner side edge of the X plane. The mirror MEMS is placed on the Y plane so as to be rotatable on two axes of the X axis and the Y axis. It is due to the arbitrary rotation and arbitrary position location within the two-dimensional plane of the mirror MEMS that the laser beam reflected by the mirror MEMS can be projected in any direction within a "pyramid" space defined by the amount of rotation of these two axes. And when the mirror MEMS is in a state of high-speed rotation, the reflected laser beam may fill the entire space of the rectangular pyramid.

The biaxial electromechanical structure is driven by the galvanometer driving module 150, and the galvanometer driving module 150 sends a driving instruction to the biaxial electromechanical structure, so that the voltage, the current, the frequency or the waveform of the reflector MEMS is adjusted. The instructions of the mirror driving module 150 may also be generated by a user, for example, the lofting laser apparatus 100 is handheld and has an interface for the user to operate, and the user inputs a desired laser beam shape, frequency, and the like according to the user's desire, thereby driving the mirror MEMS.

Referring to fig. 1, in a preferred or alternative embodiment, the lofting laser apparatus 100 includes a second laser diode and image processing module 170, and after the target image 210 is presented on the target object 200, the second laser diode detects the target image 210 and forms a detection image as a comparison object for detecting whether the target image 210 is accurate. After the detection image is formed, the second laser diode converts the detection image into a detection signal, namely, converts the optical signal into an electric signal. The image processing module 170 is in communication connection with the second laser diode, receives the detection signal, and forwards the detection signal to the central processing module 110, the central processing module 110 compares the detection signal obtained by feedback with the target image 210 input by the user from the external device in real time, and if the detection signal does not match the target image 210, the central processing module adjusts the control instruction to compensate and adjust the target image 210, and finally, the target image 210 is accurately presented.

The user can send target image 210 to lofting laser device 100 through smart devices such as smart phones, for example, construction drawing (including door frame, window frame, etc.), decoration drawing, etc. target image 210 aims at the construction face, can be like scanning out the construction scheme (the position of door frame, the position of window frame, etc.) on the wall, the user only need follow the construction scheme operation that appears on the wall.
