I have the homography matrix and I projected a scene using that homography matrix. Now I have trajectories in 2D, I want to transform them into the projected scene.
I'm trying to do object detection in one image, and do a homography calculations of trajectories of that image, I don't know how to convert the coordinates from the detected bounding box centers of the first image to converted homography coordinates image
p = np.array(((trk[1] + trk[3]) / 2, (trk[0] + trk[2]) / 2, 1)).reshape((3, 1))
temp_p = H.dot(p)
sum = np.sum(temp_p, 1)
px = int(round(sum[0] / sum[2]))
py = int(round(sum[1] / sum[2]))
point_lists[trk[4]].append((px, py))
x = [i[0] for i in point_lists[trk[4]]]
y = [i[1] for i in point_lists[trk[4]]]
p = np.polyfit(x, y, deg=1)
y = p[1] + p[0] * np.array(x)
fitted = list(zip(x, y))
cv2.polylines(dst, np.int32([fitted]), False, color=(255, 0, 0))
