Problems solved by technology
The existing solar incident direction detection device has limitations in the angle detection range, the complexity of the detection scheme and the simultaneous measurement of the horizontal angle and the elevation angle.
Research on the sun orientation detection device based on vision, article number 1671-4598 (2008) 07-0911-03, computer measurement and control. 2008.16 (7), the scheme described in the article uses computer vision technology, but the size of the receiving screen is limited and location constraints, it is impossible to measure all incident angles
Invention patent CN 103604410 provides a sun direction detection sensor in the form of digital signal output. This solution requires stepping motors to realize time-sharing detection of horizontal angle and altitude angle. It cannot detect horizontal angle and altitude angle at the same time, and requires precise Control the rotation angle of the mechanical device in the detection mechanism

Embodiment Construction
[0025] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.
[0026] see Figure 1~4 As shown, a method for detecting the sun incident direction based on image recognition uses a bowl-shaped device whose inner wall is a standard hemispherical surface, a camera, and a computer or embedded system connected to the camera. Described inner wall is the bowl-shaped device of standard hemispheric surface, and sunlight 15 is irradiated on the bowl-shaped device, can form shadow region 1 and irradiation region 2 on the inner wall of bowl-shaped device hemispherical surface, between described shadow region 1 and irradiation region 2 The dividing line 3 is formed by the circular edge of the top of the bowl.
[0027] Paint the edge line 10 on the top of the bowl-shaped device in red, paint the inner wall of the hemisphere in blue, and paint a green cu...

The present invention discloses a sun incident direction detection method based on image recognition. A camera, a bowl-shaped device whose inner wall is a standard hemispherical surface, and a computer system which processes an image are mainly used, the orientation detection of any angle of incident light can be realized, a horizontal angle and an elevation angle can be detected at the same time, the amount of calculation is small, the hardware requirement of a computer system is low, the driving of employed equipment by a motor is not needed, and the structure is simple.
Description
technical field [0001] The invention belongs to the application field of image recognition technology, and in particular relates to a method for detecting the incident direction of the sun. Background technique [0002] The prospect of solar energy utilization is very broad. In order to ensure that the solar panel is irradiated vertically by the sun's rays, the measurement of the sun's incident direction must be realized. The existing sun incident direction detection device has limitations in the angle detection range, the complexity of the detection scheme and the simultaneous measurement of the horizontal angle and the elevation angle. Research on the sun orientation detection device based on vision, article number 1671-4598 (2008) 07-0911-03, computer measurement and control. 2008.16 (7), the scheme described in the article uses computer vision technology, but the size of the receiving screen is limited Due to the limitation of location and position, it is impossible to ...
