Description

Technical Field

[0001] This utility model relates to the field of image acquisition technology, and in particular to an image acquisition device with supplementary lighting function. Background Technology

[0002] In sports training or competition scenarios, the direction of movement of runners on the track (clockwise or counterclockwise) may change due to training needs or track rules. Traditional image acquisition equipment (such as fixed cameras) can usually only cover a single perspective, leading to the following problems: insufficient coverage, a single camera cannot simultaneously capture the complete movements of runners in different directions, requiring the deployment of multiple devices, increasing costs and maintenance difficulty; low switching efficiency, manually adjusting the camera angle is time-consuming and laborious, making it difficult to meet the needs of real-time data acquisition; poor image consistency, images acquired by different devices cause analysis errors due to angle differences, affecting the accuracy of performance judgment, which urgently needs improvement. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an image acquisition device with supplementary lighting function, comprising: a housing, an acquisition terminal for acquiring images or videos, the acquisition terminal being installed inside the housing, the acquisition terminal being able to acquire images or videos outside the housing through a first window and / or a second window, an supplementary lighting device being installed outside the housing, the supplementary lighting device being movably mounted on the housing, the supplementary lighting device being rotatable to provide supplementary lighting for a first type of object that the acquisition terminal can capture through the first window, and the supplementary lighting device being rotatable to provide supplementary lighting for a second type of object that the acquisition terminal can capture through the second window.

[0004] Furthermore, the acquisition terminal can be installed in a first position within the housing and is in a first state where images or videos can be acquired through a first window and is detachable; the acquisition terminal can be installed in a second position within the housing and is in a second state where images or videos can be acquired through a second window and is detachable.

[0005] Furthermore, the data acquisition terminal is movably installed inside the housing, and the data acquisition terminal can move from a first position / second position in the first state / second state to a second position / first position in the second state / first state.

[0006] Furthermore, the first window and the second window are arranged at the same height, and there is an angle α between the first plane where the first window is located and the second plane where the second window is located, where 45°≤α≤120°.

[0007] Furthermore, the outer shell has a horizontally arranged first plate, and the supplementary lighting device is rotatably mounted on the first plate. The first plate is arranged perpendicularly to the first plane where the first window is located. The supplementary lighting device can rotate relative to the first plate to provide supplementary lighting for a first type of object / a second type of object or for a second type of object / a first type of object.

[0008] Furthermore, the outer shell has a horizontally arranged second plate, the supplementary lighting device is rotatably connected to the second plate, and the supplementary lighting device is clamped between the first plate and the second plate.

[0009] Furthermore, the second plate has an arc-shaped groove, and the supplementary lighting device has a column that is adapted to be inserted into the arc-shaped groove. The arc-shaped groove is arranged coaxially with the rotating shaft of the supplementary lighting device.

[0010] Furthermore, when the supplementary lighting device rotates relative to the second plate to the point where the column abuts against one end of the arc-shaped groove, the supplementary lighting device will provide supplementary lighting for the first type of object; when the supplementary lighting device rotates relative to the second plate to the point where the column abuts against the other end of the arc-shaped groove, the supplementary lighting device will provide supplementary lighting for the second type of object.

[0011] In this invention, the proposed image acquisition device with supplementary lighting function achieves dual-view coverage and synchronous adjustment of supplementary lighting. The first window is aligned with the clockwise side of the track, and the second window is aligned with the counterclockwise side of the track. The windows use wide-angle lenses, such as a 150° field of view. The supplementary lighting device is driven by a motor, such as a stepper motor, to rotate within a range of 0-180°. The direction of the light source matches the viewing angle of the acquisition terminal in real time, thereby achieving full track coverage and single-device coverage of both sides of the track, solving the problem of limited viewing angle of traditional cameras. Through dynamic supplementary lighting optimization, that is, the light source is adjusted according to the shooting direction, the blurring of the athlete's outline caused by backlighting or sidelighting, such as in night training scenes, can be eliminated.

[0016] Reference Figure 1This embodiment proposes an image acquisition device with supplementary lighting function, including: a housing 1, an acquisition terminal 3 for acquiring images or videos, the acquisition terminal 3 is installed inside the housing 1, the acquisition terminal 3 can acquire images or videos outside the housing 1 through a first window 11 and / or a second window 2, an supplementary lighting device 2 is installed outside the housing 1, the supplementary lighting device 2 is movably installed on the housing 1, the supplementary lighting device 2 can be rotated to provide supplementary lighting for a first type of object that the acquisition terminal 3 can capture through the first window 11, and the supplementary lighting device 2 can also be rotated to provide supplementary lighting for a second type of object that the acquisition terminal 3 can capture through the second window 2. By using dual-view coverage and synchronous adjustment of supplementary lighting, the first window 11 is aligned with the clockwise side of the track, and the second window 2 is aligned with the counterclockwise side of the track. The windows use wide-angle lenses, such as a 150° field of view. The supplementary lighting device 2 is driven by a motor, such as a stepper motor, to rotate within a range of 0-180°. The direction of the light source matches the viewing angle of the acquisition terminal in real time, thereby achieving full track coverage and single-device coverage of both sides of the track, solving the problem of limited viewing angle of traditional cameras. Through dynamic supplementary lighting optimization, that is, the adjustment of the light source according to the shooting direction, the blurring of the athlete's outline caused by backlight or sidelight in night training scenes can be eliminated.

[0017] Furthermore, the acquisition terminal 3 can be installed in a first position within the housing 1 and is in a first state where images or videos can be acquired through the first window 11, and is detachable. The acquisition terminal 3 can also be installed in a second position within the housing 1 and is in a second state where images or videos can be acquired through the second window 2, and is detachable. The acquisition terminal 3 is movably installed within the housing 1, and can move from the first / second position in the first / second state to the second / first position in the second / first state.

[0018] Furthermore, the first window 11 and the second window 2 are arranged at the same height, with an angle α between the first plane containing the first window 11 and the second plane containing the second window 2, where 45°≤α≤120°. This optimizes the spatial layout. When α=90°, the two windows form an orthogonal field of view, covering both the straight sections and curves of the track. The window edges are coated with a gradient filter to reduce chromatic aberration interference from incident light at different angles. The projection angle of the supplementary lighting device 2 is calculated based on the angle α, ensuring that the supplementary lighting range extends to 240° when the light source covers the overlapping area of ​​the windows (e.g., when α=120°). This eliminates blind spots, with the two windows complementing each other at large angles, avoiding blind spots in the curve area. Light uniformity is improved, and the filter coating reduces glare, ensuring the clarity of the athlete's facial features.

[0019] Furthermore, the housing 1 has a horizontally arranged first plate 13, and the supplementary lighting device 2 is rotatably mounted on the first plate 13. The first plate 13 is arranged perpendicularly to the first plane where the first window 11 is located. The supplementary lighting device 2 can rotate relative to the first plate 13 to switch from supplementary lighting for a first type of object / a second type of object to supplementary lighting for a second type of object / a first type of object. The first plate 13 is made of aluminum alloy, and the rotating shaft 131 has a built-in ball bearing to achieve smooth rotation of ±90°. The surface of the plate is coated with a waterproof coating that meets the IP67 standard, making it suitable for harsh outdoor environments. The optical axis of the supplementary lighting device 2 is aligned with the normal of the window plane, and the initial angle is adjusted using a laser calibration tool. The plate base enhances structural stability and prevents the supplementary lighting from shifting in windy weather; the alignment of the optical axis reduces supplementary light scattering and improves the signal-to-noise ratio for nighttime shooting.

[0020] Furthermore, the outer shell 1 has a horizontally arranged second plate 14, and the supplementary lighting device 2 is rotatably connected to the second plate 14, with the supplementary lighting device 2 clamped between the first plate 13 and the second plate 14. The second plate 14 has an arc-shaped groove 141, and the supplementary lighting device 2 has a column 21 adapted to and inserted into the arc-shaped groove 141. The arc-shaped groove 141 is coaxially arranged with the rotating shaft of the supplementary lighting device 2. The central angle of the arc-shaped groove 21 is 110°, limiting the rotation range of the supplementary lighting device to 55° clockwise to 55° counterclockwise. A pressure sensor can be embedded in the groove to detect the position of the column 141 and feed it back to the control system. A silicone buffer pad is provided at the end of the arc-shaped groove 21 to provide tactile feedback and absorb impact when the device is in position. Mechanical limiting prevents accidental displacement of the supplementary lighting device, ensuring the continuity of data acquisition during the competition; the sensor-linked control system automatically records the supplementary lighting angle parameters for later analysis.

[0021] Furthermore, when the supplementary lighting device 2 rotates relative to the second plate 14 until the column 21 abuts against one end of the arc-shaped groove section 141, the supplementary lighting device 2 will provide supplementary lighting for the first type of object; when the supplementary lighting device 2 rotates relative to the second plate 14 until the column 21 abuts against the other end of the arc-shaped groove section 141, the supplementary lighting device 2 will provide supplementary lighting for the second type of object. The supplementary lighting intensity can be adjusted as needed, extending the battery life for outdoor use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
