An image sensor, or a photosensitive element, is a device that converts an optical image into a digital electrical signal, and is widely used in digital cameras and other electro-optical devices.

The invention can be realized by adopting the following specific technical scheme and embodiment:

the detection assembly comprises a processing unit electrically connected with an image acquisition device, wherein the image acquisition device comprises an optical imaging unit and an image unit arranged behind the optical imaging unit, the optical imaging unit forms an optical image of a target and a background thereof on the imaging unit, and the imaging unit converts the optical image into other types of information. Preferably, as the most mature technical means at present, the imaging unit is a photoelectric imaging unit, converts an optical image into an electrical image signal (for example, an analog or digital electrical signal, for example, a camera tube is one of devices generating an analog electrical image signal), and sends the electrical image signal to the processing unit, and the processing unit identifies a target image signal in the electrical image signal and implements detection of a target according to a relevant parameter of the target image signal; and judging the position condition of the target according to the position relation of the target image signal, and laying a foundation for tracking the target. The imaging unit converts the optical image into other types of information, and besides the conversion into the electric signal, the detection and judgment can be carried out by the modes of micro-particle arrangement, chemical reaction, temperature change and the like on the imaging unit and the detection mode suitable for the modes. The identification of the target image signal may be implemented by using the existing technical solution (for example, the known signal detection and determination technology), or may be implemented by using the technical means provided in the following technical solution of the present invention. In addition, as an improvement, a light filtering unit can be arranged at the front end of the optical imaging unit (towards the detected target, namely between the optical imaging unit and the detected target) so as to lay a foundation for improving the identification efficiency of subsequent target images, simplifying the identification means and prolonging the service life of the image unit.

Fig. 1 shows a schematic diagram of a technical solution implemented based on an image sensor, in which a detection component 2 includes an image sensing unit 222 connected to a data processing unit 23, an optical imaging unit 221 is disposed in front of the image sensing unit 222, the optical imaging unit 221 forms an optical image of an object a and its background on the image sensing unit 222, the image sensing unit 222 converts the optical image into a digitized electrical signal, i.e., an electrical signal representing the optical image by a plurality of pixels, i.e., a digitized image (referred to as a picture in this application), and sends the picture to the data processing unit 23, the data processing unit 23 identifies the object image in the picture, and implements detection of the object according to relevant parameters of the object image; and judging the position condition of the target according to the position relation of the target image in the picture, and laying a foundation for tracking the target. The identification of the target image may be implemented by using the existing technical solution (for example, a known image identification technology, etc.), or may be implemented by using the technical means provided in the subsequent technical solution of the present invention.

As an improvement, the optical filter unit 21 may be disposed at the front end of the optical imaging unit 221, so as to lay a foundation for improving the recognition efficiency of the subsequent target image, simplifying the recognition means, and prolonging the service life of the image unit.

The image sensing unit 222 is composed of an image sensor and a related circuit, the image sensing unit 222 may be one of a CCD or a CMOS, and a device meeting requirements is selected according to application requirements, and the selection and circuit composition of the device can be realized by using the prior art.

Further, in order to implement application to the detection result, or to implement tracking of the target, the data processing unit 23 sends the detected or obtained target tracking data to the application system 44.

As shown in fig. 1, the object a and its background at the first position form an optical image (where the optical image of the object a is a') projected to the image sensing unit 222 through the filtering unit 21 and the optical imaging unit 221, and the image sensing unit 222 converts the optical image into a digitized electrical signal, i.e., a picture 1a, on which the object image 10a is shown in fig. 1 a. Similarly, an object a (an object given by a dotted line, and no reference symbol a for simplifying the drawing, and similarly, an optical image a' corresponding thereto and no reference symbol, which is shown by a dotted line) at the second position and the background thereof form a picture 1b, and an object image 10b is provided on the image 1 b. As can be seen from the figure, the position of the target image 10 on the picture 1 of the target a at two different positions also changes, the data processing unit 23 identifies the target images 10a and 10b on the pictures 1a and 1b, and judges that the position change (which can be obtained by the change of the pixel coordinates) of the target images 10a and 10b on the pictures 1a and 1b can obtain the position change condition of the target a, and meanwhile, the change of the color, the state, the distance, the size, the shape and the like of the target a is reflected by the change of the pixel value of the target image 10 and the change condition of the number of occupied pixels, so as to realize the detection of the target. The detection result is sent to the application system 4 to meet the requirements of the relevant application.

Fig. 2 shows an embodiment of an integrated design of the detection assembly 2, in which an existing standardized camera 22 is used, and the camera 22 is connected to a data processing unit 23. The camera 22 includes an image sensor and associated circuitry, and an optical imaging system. If the camera 22 is an analog camera, a video capture card or an AD conversion module that converts an analog signal into a digital signal is connected between the camera 22 and the data processing unit 23. Of course, the camera 22 may also be an infrared camera, if necessary.

As an application, the filter unit 21 employs an optical filter adapted to the requirement. Of course, the filtering unit 21 may be omitted as needed, and a software filter or an accurate image recognition technology may be implemented by the data processing unit 23, but this may adversely affect the processing efficiency, and if the target is a high-brightness target such as the sun, the service life of the related devices of the camera 22, especially the image sensor, may be damaged if the filter is not used.

The difference between the embodiment shown in fig. 3 and fig. 2 is that the filter unit 21 employs an aperture imaging system, the aperture imaging system includes an imaging screen 212 and an imaging aperture 211 disposed in front of the imaging screen 212, meanwhile, the imaging screen 212 is made of a translucent material, an inverted real image is formed on the imaging screen 212 by the aperture for the target and the background, and the camera 22 captures an image on the imaging screen 212 to form a picture 1. Because the brightness of the target (especially for high-brightness targets such as sun and flame targets) can be reduced through the imaging small holes 211, and meanwhile, the light intensity is further reduced through the selection of the light transmission condition of the imaging screen 212, the burning of the camera is reduced, the service life of the camera is prolonged, and meanwhile, because the background image has low brightness and poor imaging effect, the filtering of the background image is realized by being assisted by the obstruction of the imaging screen 212, the interference of the background image on the target image recognition is reduced, and the target recognition effect is enhanced.

Of course, for simplicity, the camera 22 and the imaging screen 212 may not be used, and the image sensing unit 222 may be directly used, and the optical image may be directly formed on the image sensing unit 222 through the imaging aperture 211.

In the above technical solution, since the image sensor has a high image acquisition sensitivity (for example, the commonly used RGB24 is a 24-bit RGB format, each component value (or called channel value) — pixel value-occupies 8 bits, the value range of each component is 0-255, and the light intensity, color and other changes of the target are reflected in the target image by different pixel values, if the 16-bit code and the corresponding image sensor are adopted, the fineness of the image sensor is further improved) and the fineness of the pixel (the current conventional image sensor has reached the fineness of millions of pixels), the accuracy of target detection is significantly improved, and meanwhile, by a proper image recognition algorithm, real-time processing and operation can be realized, and the efficiency is improved. For example, the invention can realize the detection and the positioning of the slight change of the detection target.

In view of the characteristics of the detection assembly 2 described above, it can be applied in various fields. For example, the detection, positioning and tracking of the sun are beneficial to the collection and utilization of solar energy; for observation and positioning of aerial targets (such as birds, airplanes and other flying objects, rockets and the like); the device is used for detecting, positioning and tracking the floating objects on the sea and the water surface; detecting, positioning and tracking fire conditions and the like; adjusting and controlling the brightness of a display screen of terminal equipment such as a mobile phone and the like (detecting information such as ambient light intensity and the like through a camera on the terminal, dynamically adjusting the brightness of the display screen, and realizing continuous, accurate and real-time adjustment); anti-glare control; the automobile high beam prevention filter (a collecting component formed by a camera and the like is arranged in front of an automobile, when strong light is collected, the collecting component is arranged on a light-transmitting screen on a windshield or special glasses worn by a driver according to light intensity control so as to adjust the light transmission rate, the collecting component can also be arranged on the special glasses, and similarly, special goggles are also realized), and the like. Of course, in a specific application, the device suitable for the specific application needs to be selected according to different requirements to implement the invention.

The application will take the detection, location and tracking of the sun as an example to illustrate the relevant applications, particularly in the area of solar energy collection and utilization. Similarly, the method can be implemented by adopting similar technical schemes in other related applications.

Fig. 4 illustrates an embodiment of a sun detection, tracking application system. In the figure, the detecting component 2 and the solar energy collecting unit 43 are fixedly connected with each other or can move synchronously (the two are fixedly connected in the figure, which is a simple manner), and the plane normal N of the front end (the end for collecting the image, such as the end of the imaging small hole 211 in the technical scheme shown in fig. 3) of the detecting component 2 is parallel to and co-directional (can be coplanar or not coplanar) with the normal N of the light receiving surface (such as the lighting surface of a solar cell panel or a heat collector, a light-gathering paraboloid and the like) of the solar energy collecting unit 43. The control unit 41 is respectively connected with the detection assembly 2 and the tracking unit 42, and the tracking unit 42 drives the solar energy collecting unit 43 to move. The detection assembly 2 sends the detected sun data to the control unit 41, the control unit 41 forms a control signal according to the detection result, and controls the action of the tracking unit 42, so that the solar energy collection unit 43 tracks the moving sun. Under the scheme, the detection assembly 2 and the solar energy collection unit 43 are opposite to the solar energy (the normal directions of the detection assembly 2 and the solar energy collection unit 43 are parallel to the sunlight and are pointed to the sun), the detection assembly 2 records the pixel coordinate position (C, C) of the sun image (target image) at the moment, when the sun moves, the pixel coordinate position of the sun image changes, the control unit 41 controls the action of the tracking unit 42 according to the pixel coordinate change amount to rotate the solar energy collection unit 43 and the detection assembly 2, and when the sun image position detected by the detection assembly 2 reaches the pixel coordinate position (C, C), the solar energy collection unit 43 is in an opposite sun state. In certain applications, the control unit 41 may establish a relevant data log, and if it is on cloudy days, control the tracking unit 42 to act according to the data log at the same time. The detection assembly 2 can collect the detection result of the sun in real time in a continuous or discontinuous mode, and the discontinuous mode collection can be, for example, video collection meeting the precision requirement or a photographing mode with a certain time interval. The positioning of the solar image can be realized by adopting the boundary or center position positioning of the solar image, if the boundary positioning is adopted, the size of the solar image can be changed due to the change of the solar height, and therefore, the boundary positioning is realized by matching one side or a plurality of sides. The detection assembly 2 adopts the image sensor to obtain the sun image information, so that the accuracy is high, the real-time performance is strong, and the response is fast.

Fig. 5 shows another embodiment of the solar detection and tracking application system, which is different from the technical solution in fig. 4 in that the detection assembly 2 is not directly connected to the solar energy collection unit 43, the position of the detection assembly 2 is fixed, and the tracking unit 42 only controls the movement of the solar energy collection unit 43. When the sun moves, the control unit 41 calculates the offset according to a preset rule according to the current position of the sun image detected by the detection assembly 2, controls the action of the tracking unit 42, and rotates the solar energy collection unit 43 to enable the solar energy collection unit to be in a state of facing the sun. In this embodiment, a rule is required to be established for the position of the sun image collected by the detection assembly 2 and the position relationship of the solar energy collection unit 43 relative to the sun, and the design of the control unit 41 is relatively complex.

FIG. 6 illustrates yet another embodiment of a sun detection, tracking application; in this figure, the control unit 41 is not separately illustrated in order to simplify the drawing, and the control unit 41 may be provided integrally with the detection assembly 2 or the regulation unit 44. The detection component 2 detects the intensity, position and other information of the solar ray, controls the regulation and control unit 44 arranged in front of the solar collection unit 43 (towards the sun direction), and the regulation and control unit 44 performs transmittance, refraction or reflection angle according to the intensity, position and other information, so that the solar collection unit 43 has the solar collection efficiency or collection requirement meeting the requirement. For example, if the sunlight is too strong, the control unit 44 reduces the light transmission amount to ensure that the solar energy collecting unit 43 works stably.

Yet another embodiment of a sun detection, tracking application system is presented in fig. 7 as an application to other application systems of solar energy. In the figure, the control unit 41 is not separately illustrated in order to simplify the drawing, and the control unit 41 may be provided integrally with the inspection unit 2 or the solar application system 45. The solar energy application system 45 can adjust the state of the solar energy application system according to the change of the solar light intensity, the position and the like, so as to meet the application requirements.
