Embodiment 1
[0059] As described below, an embodiment of the present invention provides a method for determining the actual position of an object in a fisheye camera image.
[0060] refer to figure 1 The flow chart of the method for determining the actual position of an object in a fisheye camera image is shown in detail below through specific steps:
[0061] S101. Determine the included angle between the positive direction of the fisheye camera image and the positive direction of the world coordinate system.
[0062] Such as figure 2 , image 3 As shown, in some embodiments, said determining the angle (θ) between the positive direction of the fisheye camera image and the positive direction of the world coordinate system includes:
[0063] Place the calibration board under the fisheye camera lens, and calculate the position of each corner point on the calibration board;
[0064] The angle between the positive direction of the fisheye camera image coordinate system and the positive dir...
Embodiment 2
[0089] As described below, an embodiment of the present invention provides a device for determining the actual position of an object in a fisheye camera image, including:
[0090] a processor adapted to load and execute instructions of a software program;
[0091] A memory adapted to store a software program comprising instructions for performing the following steps:
