Speed Check Camera description

I made this app to measure the speed of a object by camera.

[★ How to use 1]
◆ The distance to a object is known

Please input "Distance" of Manual_Setting.

If you chase a object by moving the Screen, speed will be displayed.
If you chase a object that is moving across , you can measure accurately.

[★ How to use 2]
◆ The distance to a object is not known

Please input "Camera_Height" of Manual_Setting.
"Camera_Height" is the height of camera position. (the position of your eye)
I think this value is your height minus 10cm.

Fit a object's foot to the center of the screen , press "AutoSet Distance" button.
Then, the distance is automatically input.
It's is necessary that you are in horizontal against a object.

If you chase a object by moving the Screen, speed will be displayed.
If you chase a object that is moving across , you can measure accurately.

[Other measured values ]
Azimuth is the direction of the compass's pointer.
Azimuth is compared to Airplane,traveling direction is azimuth.

Pitch is the slope of up and low.
Pitch is compared to Airplane, the slope of head is the pitch.

Roll is the slope of the main wing.

Gyro is the speed of rotation.

Unit that this app offers is "m/sec" and "km/hour".
