Below in conjunction with Figure of description and embodiment, the utility model content is described in detail:
Be illustrated in figure 1 the schematic flow sheet of a kind of camera stabilizer that the utility model provides, it comprises microcontroller, MEMS gyro instrument chip 1 (Micro-Electro-Mechanical Systems) and video camera deflection module; Described microcontroller is connected with MEMS gyro instrument chip, video camera deflection module respectively; Described MEMS gyro instrument chip is fixed on video camera, and it is for the deflection angle data of acquisition camera, and the data that described microcontroller collects according to MEMS gyro instrument chip send rotation command to steering wheel; Described video camera is fixed in video camera deflection module, and video camera deflection module is used for the rotation of actuated camera.
Microcontroller can be selected but be not limited to 8 single-chip microcomputers or the stm32f103c8t6 etc. such as HT66F70A, Atmega8, Atmega328 32 single-chip microcomputers; MEMS gyro instrument chip can be selected but be not limited to mpu6050, the model chip such as mpu9150, mpu9250.
Described video camera deflection module comprises X-axis 360 ° of steering wheels 2, Y-axis 360 ° of steering wheels 3 and Z axis 360 ° of steering wheels 4.Three 360 ° of steering wheels are respectively used to control the deflection of video camera around X-axis line, Y-axis line and z axis three directions.Correspondingly, deflection angle data comprise the angle of pitch (angle around three-dimensional coordinate X-axis rotates) of video camera, yaw angle (angle around three-dimensional coordinate Y-axis rotates), the amount of deflection of roll angle (anglec of rotation around three-dimensional coordinate Z axis) three angles and this three angle rotating angular acceleration data.
As shown in Figure 2, the side that X-axis 360 ° of steering wheels 2 are fixed on video camera 6 is rotated around X-axis line to drive video camera; Y-axis 360 ° of steering wheels 3 are fixed by right angle pole 5 and X-axis 360 ° of steering wheels 2, and Y-axis 360 ° of steering wheels 3 rotate indirectly to drive video camera 6 to rotate around Y-axis line around Y-axis line by driving X-axis 360 ° of steering wheels 2; Z axis 360 ° of steering wheels 4 are fixed with Y-axis 360 ° of steering wheels 3 by another right angle pole 5, and Z axis 360 ° of steering wheels 4 rotate around z axis by driving Y-axis 360 ° of steering wheels 3 to rotate indirect X-axis 360 ° of steering wheels 2 and the video camera 6 of driving around z axis.
In the utility model, camera stabilizer also comprises host computer (as mobile terminals such as mobile phones), this host computer is connected with microcontroller by Bluetooth communication modules, and the data received by it and the instruction that sends are sent to host computer and preserve for operating personnel and check by described microcontroller.During owing to considering capture video, most photographer takes with the angle of photographer oneself, and long-distance remote control seems and wastes one's talent on a petty job, therefore carries out wireless remote control with bluetooth 2.0 radiotechnics of short haul connection.
Here is the utility model one specific embodiment:
For convenience of description, in the present embodiment, HT66F70A single-chip microcomputer selected by microcontroller, and MEMS gyro instrument chip selects mpu6050 chip, and 360 ° of steering wheels select CS929MG type steering wheel.
MEMS (micro electro mechanical system) (Micro-Electro-Mechanical Systems) motion-sensing chip is moving towards higher integrated level, less chip size, lower cost and higher performance.MEMS accurately can determine the orientation of moving object, the information such as acceleration.
In the present embodiment, with securing member, MEMS gyro instrument chip is fixed on bottom of camera, the deflection angle (angle of pitch, yaw angle and roll angle) of acquisition camera and the rotary acceleration of each angle is come by MEMS gyro instrument chip, utilize serial bus protocol to communicate with HT66F70A single-chip microcomputer again, MEMS gyro instrument chip can be gathered three axle rotating angular acceleration data of video camera in real time.
The above-mentioned exercise data that HT66F70A single-chip microcomputer collects, obtain the deflection angle that current steady device three-dimensional axis is expected, and convert the controlled quentity controlled variable of each axle CS929MG steering wheel angle, speed etc. to, output to each CS929MG steering wheel, control the angle that steering wheel rotates, realize the compensation of angle, to reach three axle frame stabilization effects of the video recording equipments such as camera.The utility model also coordinates keyboard (host computer) implementation pattern to select by outside, the adjustment of camera perspective, and the adjustment of motor action sensitivity.
Consider the weight of stepping motor, volume is large, but energy precise control of angular degree, there is brushless motor volume little, lightweight, but can not the anglec of rotation be controlled.It is little that described the present embodiment have chosen volume, lightweight CS929MG steering wheel.
CS929MG steering wheel can control rotating and the rotating speed of motor, and moment is large, and Angle ambiguity is accurate, is commonly used in mechanical arm, the technology occasions such as robot, is responsible for the control of rotational angle.CS929MG steering wheel is by direct current machine, and train of reduction gears and control circuit composition are the systems of a set of open loop.By the control line of CS929MG steering wheel, just can control the speed of motor, turn to.
The control line of CS929MG steering wheel, control signal pulse-width modulation (PWM) signal, control cycle is the corner action that the square-wave signal duty ratio of 20ms just can control steering wheel.
Steering wheel " command list "
In addition, in the present embodiment, the outside liquid crystal of easily extensible, keyboard or use cell-phone customer terminal check the state of stabilizer, and the operational mode of setting stabilizer.Stabilizer can set the state of plurality of stable, and as visual angle immobilizes, or uniform rotation is stablized with rotation direction in visual angle.
