[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] In the related art, the marking of installation points is mainly carried out by a large laser line-laying instrument in combination with manual marking. However, the internal space of the vacuum container is small and the surface is curved. The projection of large laser projection tools is prone to distortion and deviation, and the projection accuracy cannot be guaranteed. In order to solve or improve the problem of distortion and deviation in the projection of laser projection tools in the related art, an auxiliary positioning device is provided in an embodiment of the present invention.

[0036] Combine the following Figures 1 to 3 , describes the auxiliary positioning device provided in an embodiment of the present invention.

[0037] Specifically, the auxiliary positioning device can be wearably set, for example, the auxiliary positioning device can be worn on the head, shoulders, chest or arms of the human body.

[0038] The scanning device 1 is used to scan the structural information of any area of ​​the vacuum container. Specifically, the scanning device 1 includes but is not limited to a laser scanner, for example, a laser scanner has a laser transmitter and at least two laser scanning heads. The laser scanner sends a laser to the measured area of ​​the vacuum container through the laser transmitter, and uses the laser scanning head to capture the reflected laser points, and measures the distance by calculating the flight time or phase difference of the laser. The laser points received by the laser scanning head can be used to construct three-dimensional point cloud data of the measured area, and then a model of the measured area is established through the three-dimensional point cloud data. Of course, the scanning device 1 can also be set as a camera three-dimensional scanning system.

[0039] The processing unit 2 is connected to the scanning device 1 in communication so that the scanning device 1 can transmit the structural information to the processing unit 2. The processing unit 2 is used to obtain the coordinate information of the area corresponding to the structural information according to the three-dimensional model and structural information of the vacuum container, and obtain the corresponding installation information according to the coordinate information. Specifically, the three-dimensional model of the vacuum container can be transmitted to the processing unit 2 in advance. The processing unit 2 compares and analyzes the received structural information with the three-dimensional model to obtain the structure in the three-dimensional model that has the same structural features as those contained in the structural information. The position of the structural information corresponding to the three-dimensional model is determined by the position of the structure in the three-dimensional model, that is, the coordinate information of the structural information is determined. Finally, according to the coordinate information, the installation information corresponding to the coordinate position in the three-dimensional model is obtained. For example, the installation information includes but is not limited to the point information of the fixing bolt, the model information of the fixing bolt, the point information of the fixing clip, and the model information of the fixing clip.

[0040] The projection device 3 is connected to the processing unit 2 for communication, and is used to project the installation information to the area corresponding to the structural information, that is, the projection device 3 projects the installation information to the area on the inner surface of the vacuum container corresponding to the structural information, that is, the area of ​​the vacuum container scanned by the scanning device. Optionally, the projection device 3 is configured as a laser projector.

[0041] In this embodiment, by making the auxiliary positioning device wearable, the operator can wear the auxiliary positioning device to enter the vacuum container, and the auxiliary positioning device always follows the operator. The scanning device 1 can obtain the structural information of the corresponding area of ​​the inner surface of the vacuum container, and the processing unit 2 can obtain the coordinate information of the structural information based on the structural information and the three-dimensional model of the vacuum container, and obtain the corresponding installation information based on the coordinate information. The projection device 3 can project the installation information to the area on the inner surface of the vacuum container corresponding to the structural information.

[0042] In this way, the auxiliary positioning device can be wearably set, so that the auxiliary positioning device always follows the operator to ensure the accuracy and pertinence of the projection. According to the scanning device 1, the structural information of the corresponding area of ​​the vacuum container can be accurately obtained, so as to accurately obtain the installation information corresponding to the area where the structural information is located in the three-dimensional model, and project it onto the inner surface of the vacuum container, so as to solve the problem of distortion and deviation of large laser projection tools in related technologies, and improve the projection accuracy.

[0043] In addition, the auxiliary positioning device can automatically project corresponding installation information according to the different scanning areas of the scanning device 1, so as to accurately and efficiently project the installation information of each area in the vacuum container, thereby improving work efficiency.

[0044] In some embodiments provided by the present invention, the scanning device 1 and the projection device 3 are both connected to the processing unit 2 by means of a wireless communication module. In this way, no cables are required between the scanning device 1 and the projection device 3 and the processing unit 2, so that only the scanning device 1 and the projection device 3 can be worn on the human body without wearing the processing unit 2 on the human body, so as to reduce the weight worn by the operator and reduce the burden on the operator.

[0045] Optionally, the wireless communication module includes but is not limited to a WiFi module, a Bluetooth module, a Zigbee module and a 4G module.

There is no need to wear the scanning device 1 and the projection device 3 on the human body separately, making it more convenient to put on and take off, and making the auxiliary positioning device more integrated and compact.
