The present disclosure relates to a camera viewing angle adjustment method and device, and belongs to the technical field of image processing. The method includes: acquiring a reference image captured within the viewing angle of the camera; graying the reference image; and calculating the gray value of each pixel on the reference line for each reference line on the reference image sum, to obtain the total gray value of the reference line, the reference line is one of the rows and columns on the reference map; according to the total gray value of each reference line, it is reminded to adjust the camera’s perspective. It solves the problem that the image obtained when the user adjusts the camera angle of view according to his own feeling still has an unreasonable composition problem; realizes that when the image composition obtained by using the camera is unreasonable, the user is reminded to adjust the camera angle of view to achieve In order to improve the effect of user experience.

The invention provides a construction method of a curb stone. First, the "double-line control method" is used to install the curb stone, and then the "gantry support construction technology" is used to manufacture the curb stone backrest, and finally the asphalt is paved. The "double-line control method" speeds up the installation speed, reduces adjustments, and improves the straightness and appearance quality of the vertical stone; the "gantry support construction technology" speeds up the installation speed of the vertical stone backrest and concrete formwork, thereby greatly reducing labor. The investment of personnel and the improvement of the construction quality have provided a basic guarantee for the subsequent asphalt concrete construction, ensured the overall smoothness of the road surface, and achieved good results such as beautiful road surface, straight line and comfortable driving. Compared with the traditional technology, it reduces the workload of construction control such as measurement, verification, and inspection, and at the same time improves work efficiency and shortens the construction period. It has good social and economic benefits. The application space has promotion value.

The invention relates to a metro vehicle assembling process, in particular to a metro vehicle wallboard mounting device and a using method. The metro vehicle wallboard mounting device and the using method mainly solve the technical problems that in the prior art, after upper wallboards are mounted on a metro vehicle, lower wallboards need to be repeatedly adjusted and paired during installation, the mounting time is long, and due to the fact that the wallboards are not consistent in installation stress, quality problems such as staggered jointing of the upper and lower wallboards frequently occur. The metro vehicle wallboard mounting device comprises a supporting rod, a length adjusting device, a torque adjusting device, a gradienter and a protection device. After wallboards are supported by the length adjusting device and the supporting rod, the supporting rod is observed and adjusted through the gradienter to guarantee a horizontal mounting face, the torque adjusting device guarantees consistent stress on the wallboards, and thus the metro vehicle wallboards are mounted.

The invention discloses an integral lifting method for a discharging platform. The integral lifting method includes the steps: enabling the discharging platform to climb along an attached lifting scaffold under pulling of an auxiliary pull rope until the discharging platform is 50cm higher than a first floor plate, stopping climbing of the attached lifting scaffold and detaching a bracket from the discharging platform; continuing climbing of the discharging platform until the discharging platform is 50cm higher than a second floor plate, detachably and fixedly connecting the bracket with the discharging platform, disconnecting a stress rope and a safety rope from a third floor plate and fixing the stress rope and the safety rope to a fourth floor plate; enabling the discharging platform to descend along the attached lifting scaffold until the bracket is abutted to the second floor plate. By optimizing the lifting steps, the bracket contacts with a target floor to serve as a criterion of in-place lifting of the discharging platform, and the lifting efficiency of the discharging platform is greatly improved. In addition, safety of the discharging platform in the lifting process is further improved.

The invention discloses a device for detecting moisture content of machine-fried Duyun Maojian tea based on spectral characteristic parameters. Its structure includes a base, a sample chamber, a detector, a power supply, a light source, and an interferometer. There is a detector, an interferometer is set on the right side of the sample chamber, a power supply is installed behind the sample chamber, a light source is installed on the right side of the power supply, a magnetic suspension device and a uniform sample device are installed in the sample chamber, and the uniform sample device is set above the magnetic suspension device , The magnetic suspension device includes a magnetic suspension base, a suspension, a whiteboard, and a tray. The suspension is arranged above the magnetic suspension base, the top of the suspension is connected to a tray, and the inner bottom of the tray is provided with a whiteboard. Spreading the material can make the tea leaves evenly distributed, avoiding manual placement and multiple adjustments, and using the principle of magnetic levitation to place the tray in the air can prevent the vibration of the equipment from displacing the tea leaves in the tray, thereby improving the detection accuracy.

The present invention provides a gas analyzer sample gas chamber apparatus with a characteristic of easy optical path adjustment. The gas analyzer sample gas chamber apparatus comprises a sample gas chamber pipe, a proximal end spherical reflecting mirror and a distal end spherical reflecting mirror, wherein the proximal end spherical reflecting mirror and the distal end spherical reflecting mirror are arranged inside the sample gas chamber pipe. The gas analyzer sample gas chamber apparatus further comprises an adjustment device forming a sealed connection with the inner wall of the sample gas chamber pipe and provided for adjusting a distance between the proximal end spherical reflecting mirror and the distal end spherical reflecting mirror, wherein the distal end spherical reflecting mirror or the proximal end spherical reflecting mirror is connected with the adjustment device. According to the present invention, during detection, the adjustment device arranged on the inner wall of the sample gas chamber pipe can be adjusted, such that the distance between the proximal end spherical reflecting mirror and the distal end spherical reflecting mirror can be correspondingly changed so as to meet detection requirements; and the adjustment device is adjusted, such that the distance between the distal end spherical reflecting mirror arranged on the adjustment device and the proximal end spherical reflecting mirror is correspondingly changed so as to avoid multiple adjustment processes of the distal end spherical reflecting mirror and effectively reduce labor intensity of operators.
