Motion capture system based on real bird flight and control method thereof

Abstract

The invention discloses a motion capture system based on real bird flight and a control method thereof, and belongs to the technical field of motion capture. The motion capture system includes a bird to be observed, a head sensor, a first humerus sensor, a second humerus sensor, a first ulna and radius sensor, a second ulna and radius sensor, a first metacarpal bone sensor, a second metacarpal bone sensor, a tail bone sensor, communication equipment and data receiving software of a ground base station. The head sensor, the first humerus sensor, the second humerus sensor, the first ulna and radius sensor, the second ulna and radius sensor, the first metacarpal bone sensor, the second metacarpal bone sensor, the tail bone sensor and a main development board are worn on a real bird body, and after a power supply is switched on, communication equipment and equipment of a ground base station are paired; and then the sensors on all bone positions are initialized, SPI, I2C and wireless communication are checked, the birds are released, and finally the flight attitudes of the birds can be observed through coupling parameters of a ground base station.

Description

technical field [0001] The invention belongs to the technical field of motion capture, and in particular relates to a motion capture system based on real bird flight and a control method thereof. Background technique [0002] The current motion capture devices on the market are generally only used for human gesture capture, such as figure 1 As shown, a wearable multi-single-point multi-axis sensor coupling motion posture capture system is often used. Due to the large size of the inertial sensor used, it is not cumbersome for humans to wear, but it is already very heavy for birds. ; If it is used on birds, it is very easy to cause the birds to be unable to fly after wearing it. [0003] The wearable sensors currently used on the market need to wear more than 15 sensors all over the body, so it is very easy to lose the sensor. Once one of the sensors is lost, the motion capture system will fail, and the human motion capture device currently used , there are many additional a...

Problems solved by technology

[0002] The current motion capture devices on the market are generally only used for human gesture capture, such as figure 1 As shown, a wearable multi-single-point multi-axis sensor coupling motion posture capture system is often used. Due to the large size of the inertial sensor used, it is not cumbersome for humans to wear, but it is already very heavy for birds. ; If it is used on birds, it is very easy to cause the birds to be unable to fly after wearing it

[0003] The wearable sensors currently used on the market need to wear more than 15 sensors all over the body, so it is very easy to lose the sensor. Once one of the sensors is lost, the motion capture system will fail, and the human motion capture device currently used , there are many additional additional functions, resulting in a single sensor that is larger in size and heavier in weight, making it more inappropriate to wear on birds

[0004] There is no current design and development status of the motion capture system for birds, and a new capture system for birds is designed
