The camera's sensor changes directionHere are some ways to change the direction of the camera sensor:
- When adjusting the direction of the camera sensor in the gazebo, you can add it in line 271 of the dofbot.gazebo.urdf.xacro file. If the angle position is not correct after adding the camera to the robotic arm, after the camera is normally written as Link&Jiont and the model position is confirmed, change the angle data<pose>0000300 in</pose>line 40 to adjust the direction of the sensor.
- For the security monitoring equipment, an infrared sensor was installed outside the second extension rod. When the infrared sensor sensed people in different directions, the servo-motor inside the shell worked to drive the rotating shaft to rotate the rotating block, thereby adjusting the direction of the camera (including the ordinary camera and the infrared camera) to indirectly change the direction of the sensor.
- In the Android system, the camera's sensor direction had a default definition. When the phone was facing the screen horizontally and the camera was close to the top, it was the default direction. When the phone was upright and the front and rear cameras were both above, the front camera's rotation angle was 270 degrees, and the rear camera was 90 degrees. For the camera's previewing direction, you can get the rotation angle through the CameraInfo.orientation parameters, and then use the Camera.setDisplayOrientation(int degree) method to set the previewing angle. For the photo storage direction, you can set the rotation in Camer.parameters. Different phones have different processing of the photo's orientation and the orientation in the EXIF information. You may need to read the EXIF information in the photo (JPEG file) to rotate the Bitmap according to the orientation to achieve the purpose of adjustment.

The History of the Development and Changes of Chinese Lyric PoetryThe history of the development of Chinese lyric poetry can be traced back to ancient times. In the pre-Qin period, poetry had already begun to appear. For example, some works in the Book of Songs were created during this period. In the Han Dynasty, lyric poetry was further developed, such as Li Sao and Han Yuefu.
In the Tang Dynasty, lyric poetry reached a peak and was known as the " prosperous Tang of the history of poetry." The poetry of this period was mainly composed of lyric poems, such as the works of Li Bai and Du Fu.
In the Song Dynasty, lyric poetry began to decline, but it still had important artistic value. During this period, the creation of poetry paid more attention to the expression of ideology and philosophy, such as the works of Su Shi, Xin Qiji and other poets.
In the Ming and Qing Dynasties, lyric poetry began to rise again, but compared with the Tang and Song Dynasties, the style and content were different. During this period, the creation of poetry paid more attention to the performance of social reality, such as the works of Cao Xueqin, Li Qingzhao and other poets.
Generally speaking, the history of the development and change of Chinese lyric poetry has gone through many periods, and the creation of poetry in different periods has its own unique characteristics and styles.
Fate Lyric Chinese LyricThe Chinese lyrics of Destiny include the following: I don't know much about love. I never thought that love would come like this. In front of love, my heart is still not so stable. If I knew this, I wouldn't have started. I'm like a fool. I regret it now. I'm praying that you don't love me. I'm praying that the person who loves me shouldn't be you. You've been lying to me. There can be no love between you and me.
LyricThe following is part of the lyrics of Ai Chen's "Fall": Who pulled down a ray of light from the night and disturbed the already silent heart? The bright moon hung high in the sky, the breeze and the stars pierced through, listening to the lament that the beauty had followed the world of mortals, turning into a waning grass, a long oriole flying and a long life. Love two two three three, but always think of drifting with the passing years. Flowers bloom and fall, the sun rises and the sun disappears, true feelings are like smoke waves, people only know loneliness. Who cares about karma, the ebb and flow of the tide, the full moon and the moon. See through but don't say it, who can tell? With the world of mortals into waning grass long orioles fly long life fall, but always think of drifting with the fleeting years. Flowers bloom and fall, the sun rises and the sun disappears, true feelings are like smoke waves, people only know loneliness. Who cares about karma, the ebb and flow of the tide, the full moon and the moon. See through but not break, too thin and who can say.
