Resolution is the most basic parameter of the camera, determined by the chip resolution used by the camera, and is the number of cells arranged on the target surface of the chip.Usually, the resolution of the surface array camera is represented by two numbers, horizontal and vertical resolutions, such as: 1920 (H) x 1080 (V). The preceding number represents the number of cells in each row, that is, there are 1920 cells in total, and the following number represents the number of rows of cells, that is, 1080 rows.Now the resolution of the camera usually indicates how much K, such as 1K (1024), 2K (2048), 3K (4096), etc.When acquiring images, the resolution of the camera has a great impact on image quality.When imaging the same large field of view (scenery range), the higher the resolution, the more obvious the display of details.
