Description

Technical Field

[0001] The present invention belongs to the technical field of electrical components, and specifically relates to semiconductor devices, and in particular to a CMOS sensor device, an image processing system and a working method. Background Art

[0002] In the agricultural planting process, it is necessary to obtain images of the planting area through image acquisition, and then obtain crop parameters from the images, such as parameters including: vegetation coverage, number of missing seedlings, biomass, and nutrient status. In the related technology, image acquisition is performed through a single acquisition module. The single acquisition module is composed of a lens array and a photosensitive unit. After the light passes through the lens array, it is irradiated on the photosensitive unit to form an image. The lens array is composed of three lenses: red, green, and blue. A single lens can only transmit light of one color. At this time, the other colors of the corresponding part of the lens on the image are synthesized and supplemented by the algorithm. The algorithm cannot perfectly restore the actual color, which will result in the image being unable to accurately reflect the actual color of the environment; because when multiple photosensitive units are set, data interference is prone to occur during the imaging process.

[0003] Therefore, since there are parts on the image that cannot accurately reflect the actual color, it is necessary to design a CMOS sensor device, an image processing system and a working method.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component may be directly formed on the second component, or the third component may be interposed between the first component and the second component. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0024] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] like Fig.10 As shown, at least one disclosed embodiment provides a CMOS sensor device, comprising: a silicon substrate 4, and at least four photosensitive units 1 arranged on the silicon substrate 4; the photosensitive units 1 are arranged side by side along the length direction of the silicon substrate 4; a lens array 11 is arranged on the photosensitive unit; after light passes through the lens array 11, it is irradiated on the photosensitive unit 1 to form an image; a plurality of groups of gold wires 41 are arranged on the silicon substrate 4 along the width direction of the silicon substrate 4, and each group of gold wires 41 is provided with four gold wires 41 to correspond to the four photosensitive units 1 respectively, and each group of gold wires 41 The length of the gold wire 41 increases gradually from top to bottom; the relevant image is collected by a single collection module, and only one photosensitive unit 1 is provided on the silicon substrate 4. The gold wires 41 corresponding to the photosensitive unit 1 on the silicon substrate 4 can be arranged relatively sparsely, and there will be no interference between adjacent gold wires 41. However, only one photosensitive unit 1 cannot meet the requirement of accurately reflecting the actual color of the environment, and thus at least four photosensitive units 1 are used in this embodiment. However, the four photosensitive units 1 will cause the corresponding gold wires 41 to be arranged relatively closely on the silicon substrate 4, for example, one The photosensitive unit 1 needs to have four corresponding gold wires 41. If the four gold wires 41 corresponding to one photosensitive unit 1 are arranged from top to bottom, and the gold wires 41 of other photosensitive units 1 continue to be arranged downward, the gaps between adjacent gold wires 41 are small. When one photosensitive unit 1 is working, the four corresponding gold wires 41 are easily interfered due to the small gaps, resulting in the inability of the photosensitive unit 1 to accurately form an image. Therefore, the arrangement method of the gold wires 41 is modified during the arrangement process to avoid interference. The specific arrangement method can be that the top gold wire 41 in a group of gold wires 41 is the shortest, and the bottom gold wires 41 are the shortest. The wire 41 has the longest length. The shortest gold wire 41 can be connected to the leftmost photosensitive unit 1 on the silicon substrate 4, and the longest gold wire 41 can be connected to the rightmost photosensitive unit 1 on the silicon substrate 4. When a photosensitive unit 1 is working, there are gold wires 41 corresponding to other photosensitive units 1 between two adjacent gold wires 41 of the gold wires 41 corresponding to the photosensitive unit 1. At this time, other photosensitive units 1 are not working. The gold wires 41 of other photosensitive units 1 can block clutter signals, so that the corresponding adjacent gold wires 41 in the working photosensitive unit 1 will not interfere with each other.

For the upper left corner position of an array, the first color lens 13 in the lens array 11 is a color lens 13 that can transmit blue light, the second color lens 13 in the lens array 11 is a color lens 13 that can transmit red light, and the third color lens 13 in the lens array 11 is a color lens 13 that can transmit green light. When multiple images are subsequently overlapped to obtain a final image, each position of the final image can ensure that its color is obtained by the color of the transmitted light reflected on the photosensitive unit 1, ensuring that the actual color of the actual environment can be accurately reflected in the final image, ensuring the accuracy of the final image, and then ensuring that accurate identification can be performed when identifying required parameters from the final image.

When it is necessary to take images, the CMOS sensor device can be manually controlled by a remote control. The type of the main color of the area to be photographed can be manually determined. For example, if the area to be photographed is a forest and its main color is green, the green color lens 13 is manually controlled by a remote control. The lens array 11 is first moved to the lens module 3. After the photosensitive unit 1 corresponding to the lens array 11 outputs the image to the control module, the remaining two lens arrays 11 corresponding to the photosensitive units 1 composed of the color lenses 13 are manually controlled by the remote control to move to the lens module 3. The control module overlaps and combines the three acquired images into a final image.
