Abstract:
A 3-D path detection system includes an image capture device, a radar device and a computing module. The image capture device is provided to produce a dynamic image for calculating the x- and y-direction (transverse) pixel-value displacements according to a captured moving object image. The radar device is configured to transmit an input wireless signal to a moving object and receive a reflection signal from the moving object, and is configured to calculate a z-direction (longitudinal) displacement of the moving object according to a Doppler shift in the reflection signal. The computing module is configured to construct a 3-D path of the moving object according to the x- and y-direction pixel-value displacements of the moving object image and the z-direction displacement of the moving object.

Claim (Index 8):
The 3-D path detection system in accordance with  claim 1 , wherein the computing module is configured to perform a calibration procedure as follows: the moving object moves along a straight path in the xz plane with a first angle relative to x-axis and then moves along a straight path in the yz plane with a second angle relative to y-axis, and the first and second angles are the predetermined angles, wherein according to the x- and y-direction pixel-value displacements of the moving object image and the z-direction displacement of the moving object, the computing module is configured to calculate a first conversion coefficient from the x-direction pixel-value displacement of the moving object image to an x-direction displacement of the moving object and calculate a second conversion coefficient from the y-direction pixel-value displacement of the moving object image to a y-direction displacement of the moving object, and the calculation formulas of the first and second conversion coefficients are represented as follows: m x = \u0394 \ue89e \ue89e x \ue8a0 ( cm ) \u0394 \ue89e \ue89e P x \ue8a0 ( pixel ) = \u0394 \ue89e \ue89e z \ue8a0 ( cm ) \u0394 \ue89e \ue89e P x \ue8a0 ( pixel ) \u00d7 tan \ue89e \ue89e \u03b8 x m y = \u0394 \ue89e \ue89e y \ue8a0 ( cm ) \u0394 \ue89e \ue89e P y \ue8a0 ( pixel ) = \u0394 \ue89e \ue89e z \ue8a0 ( cm ) \u0394 \ue89e \ue89e P y \ue8a0 ( pixel ) \u00d7 tan \ue89e \ue89e \u03b8 y wherein m x  is the first conversion coefficient, \u0394z is the z-direction displacement of the moving object, \u0394P x  is the x-direction pixel-value displacement of the moving object image, \u03b8 x  is the first angle, \u0394x is the x-direction displacement of the moving object, m y  is the second conversion coefficient, \u0394P y  is the y-direction pixel-value displacement of the moving object image, \u03b8 y  is the second angle, and \u0394y is the y-direction displacement of the moving object.
