The invention discloses a combined imaging device based on an area array image sensor and a control method thereof. The combined imaging device comprises the area array image sensor that is arranged to align to an object plane, an optical lens is arranged between the area array image sensor and the object plane, wherein the combined imaging device is arranged between the optical lens and the object plane, multiple to-be-imaged areas are arranged on the object plane, the light emitted from the multiple to-be-imaged areas arrives at the optical lens through the combined imaging device, and refracted light forms a combined image on the area array image sensor; and the combined imaging device is an optical device that at least contains a reflection surface. By adopting the combined imaging device based on the area array image sensor and the control method thereof provided by the invention, on the basis of guaranteeing the necessary multiplying power, the length-width ratio of a detected area is adjusted to the length-width ratio of an approximate image sensor through the combined imaging device to improve the measurement efficiency.
Description
technical field [0001] The present invention relates to an imaging device and a control method thereof, in particular to a combined imaging device based on an area array image sensor and a control method thereof. Background technique [0002] Current image sensors are generally divided into line array image sensors and area array image sensors. It is a key technology in the field of automatic identification and automatic measurement to image the image of the detected area on the image sensor through an optical lens, and to process the obtained image through computer automatic identification. [0003] The detected area is mapped onto the image sensor according to the imaging magnification of the lens. When the aspect ratio of the detected area does not match the aspect ratio of the image sensor used, the image sensor cannot be utilized efficiently. Especially when testing some large-sized products, scanning and testing with a line array image sensor is a commonly used high-...
