Description

Technical Field

[0001] This invention belongs to the field of computer vision technology, specifically a real-time reminder system for music performance posture based on visual capture. Background Technology

[0002] A real-time music performance posture reminder system based on visual capture is a music-aided teaching device that integrates computer vision, human posture recognition, and real-time feedback technologies. Its core consists of three main components: a camera, a processor, and a display screen. The camera is responsible for capturing high-definition video streams of the performer's hand, arm, and limb movements from multiple perspectives. The processor analyzes the movement data using a built-in AI skeletal recognition algorithm and compares it with a standard performance posture template. The display screen presents images with posture deviation markers in real time, providing the performer with intuitive guidance for correcting their movements. It is widely used in scenarios such as home practice and music training institutions, helping performers quickly develop standardized performance postures. In a typical system deployment, the camera is usually mounted around the instrument using a fixed bracket, the processor is often integrated into terminal devices such as computers and tablets, and the display screen is placed nearby within the performer's peripheral vision. The three components achieve data linkage and command transmission through wireless or wired links.

[0003] In the existing technology equipment architecture, the camera mounting bracket is mostly a fixed structure, which can only achieve positioning at a single angle or height, making it difficult to flexibly adjust the position according to different types of instruments, the height of the performer, and the training focus.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1, by Figures 1-8 The present invention relates to a real-time reminder system for music performance posture based on visual capture, comprising a base 1, a bracket 4 fixedly installed at the bottom of the base 1, an adjustment mechanism 2 at the top of the base 1, and an adjustment mechanism 3 on the adjustment mechanism 2.

[0022] In Embodiment 2, based on Embodiment 1, the adjusting mechanism 2 includes a screw 201 fixed to the top of the base 1. A lifting cylinder 203 is provided on the outer side of the screw 201. A top plate 204 is fixedly connected to the top of the lifting cylinder 203. Two guide rods 2012 are symmetrically fixedly connected to the bottom of the top plate 204. Two guide holes 2011 are symmetrically provided at the top of the screw 201. The two guide rods 2012 are respectively inserted into the two guide holes 2011. Through the cooperation between the guide holes 2011 and the guide rods 2012, the top plate 204 is limited and guided, so that the lifting cylinder 203 can only move longitudinally. A drive motor 205 is fixedly installed on the top of the top plate 204. A drive shaft 206 is fixedly connected to the drive motor 205. An L-shaped plate 208 is fixedly connected to the top of 206. Two side blocks 2017 are symmetrically fixedly connected to the outer side of the L-shaped plate 208. A connecting shaft 2026 is rotatably connected between the two side blocks 2017. A mounting bracket 2027 is fixedly sleeved on the outer side of the connecting shaft 2026. A camera 2010 is installed on the outer side of the mounting bracket 2027. A screw cylinder 202 is threadedly sleeved on the outer side of the screw rod 201. An auxiliary handle is fixedly fixed on the outer side of the screw cylinder 202 to facilitate the rotation of the screw cylinder 202. An inner ring 2016 is fixedly installed on the inner side of the lifting cylinder 203. The inner ring 2016 is located on the outer side of the screw cylinder 202. Outer rings 2015 are provided on both the upper and lower sides of the inner ring 2016. Both outer rings 2015 are fixedly sleeved on the outer side of the screw cylinder 202. Multiple limiting rods 2014 are fixedly connected at equal angles on the side of the rings 2015 that are close to each other. One end of each limiting rod 2014 is provided with a ball bearing 2013 that abuts against the inner ring 2016. When the screw cylinder 202 moves longitudinally, the two outer rings 2015 drive the inner ring 2016 to move, which allows the lifting cylinder 203 to rise and fall. At the same time, by setting the limiting rods 2014 and the ball bearing 2013, direct contact between the outer ring 2015 and the inner ring 2016 is avoided, reducing the friction between the outer ring 2015 and the inner ring 2016. A support column 207 is fixedly connected to the L-shaped plate 208. The bottom end of the support column 207 is provided with a ball bearing 209 located at the top of the top plate 204. When the L-shaped plate 208 rotates, the ball bearing 209 is driven by the support column 207. The ball 209 rolls on the top of the top plate 204 to support the L-shaped plate 208 and ensure its stability during rotation. The L-shaped plate 208 is provided with a sliding groove 2023. A sliding rod 2019 is fixedly connected to the inner side of the sliding groove 2023. A sliding plate 2020 is movably sleeved on the outer side of the sliding rod 2019. A toothed plate 2024 is fixedly connected to the outer side of the sliding plate 2020. A gear 2025 is fixedly installed on the outer side of the connecting shaft 2026. The gear 2025 meshes with the toothed plate 2024. A lead screw 2022 is rotatably connected to the inner side of the L-shaped plate 208. A handwheel 2018 is fixedly connected to the bottom end of the lead screw 2022. A nut 2021 is threaded onto the outer side of the lead screw 2022. The sliding plate 2020 is fixed to the outer side of the nut 2021. When the screw cylinder 202 is rotated, since the screw cylinder 202 is threaded onto the outside of the screw rod 201, the screw cylinder 202 moves longitudinally along the screw rod 201 when it rotates. This causes the inner ring 2016 to move through the two outer rings 2015, and drives the lifting cylinder 203 to rise and fall, thereby achieving the adjustment of the height of the camera 2010. When the handwheel 2018 is rotated, the lead screw 2022 is driven to rotate, which in turn drives the slide plate 2020 to slide along the slide bar 2019 via the lead screw nut 2021, and drives the toothed plate 2024 to move longitudinally. Since the toothed plate 2024 meshes with the gear 2025, it drives the connecting shaft 2026 to rotate, and then drives the camera 2010 to rotate via the mounting bracket 2027, thereby adjusting the tilt angle of the camera 2010. When the drive motor 205 is started, it drives the drive shaft 206 to rotate, which in turn drives the L-shaped plate 208 to rotate, thus realizing the circular rotation of the camera 2010. Finally, the position of the camera 2010 can be flexibly adjusted according to different types of musical instruments, the height of the performer, and the training focus.

[0023] In embodiment three, based on embodiment one, the adjustment mechanism two 3 includes a U-shaped rod 301 fixed to the outside of the lifting cylinder 203, a lifting plate 305 movably sleeved on the outside of the U-shaped rod 301, a processor 302 provided on the outside of the lifting plate 305, a display screen 303 provided on the processor 302, a sleeve plate 304 fixedly sleeved on the outside of the U-shaped rod 301, and a roller 306 abutting against the sleeve plate 304 on the outside of the lifting plate 305. First, the lifting plate 305 slides along the U-shaped rod 301, causing the processor 302 to rise and fall. At the same time, the roller 306 rolls on the sleeve plate 304 to ensure the stability of the lifting plate 305 during movement, thereby adjusting the height of the display screen 303 as needed.

[0024] In Example 4, based on Example 1, a mounting block 309 is fixedly connected to the outer side of the lifting plate 305. An L-shaped round rod 3012 is fixedly connected between the mounting block 309 and the processor 302. A translation block 3011 is movably sleeved on the outer side of the L-shaped round rod 3012. A spring 3010 is fixedly connected between the translation block 3011 and the mounting block 309. The spring 3010 is sleeved on the outer side of the L-shaped round rod 3012. An insertion rod 308 is fixedly connected to the outer side of the translation block 3011. The insertion rod 308 passes through the mounting block 309 and is movably connected to the mounting block 309. Multiple insertion holes 307 are provided at equal intervals on the outer side of the sleeve plate 304. The insertion rod 308 is inserted into the corresponding insertion hole 307. First, slide the translation block 3011 along the L-shaped rod 3012 away from the mounting block 309. At this time, the spring 3010 deforms, and the insertion rod 308 moves horizontally until it is removed from the corresponding insertion hole 307. Then, slide the lifting plate 305 along the U-shaped rod 301 to raise and lower the processor 302 and the display screen 303. Then, release the translation block 3011. At this time, the spring 3010 resets and drives the translation block 3011 to slide along the L-shaped rod 3012 and approach the mounting block 309. At the same time, the insertion rod 308 moves horizontally until it is inserted into the corresponding insertion hole 307, fixing the lifting plate 305 to the sleeve plate 304. Finally, the display screen 303 is fixed after being raised and lowered.
