我正在尝试将https://robotbenchmark.net/上的相机用于高速公路驾驶,但是在理解相机和物体识别的手册方面有些困难。我已经能够使用camera.getRecognitionObjects()识别出一些对象,如下所示,但是我不明白如何获取特定对象的ID,距离或位置。我要帮忙的是识别道路的轮廓,以便我可以将汽车对准道路。 预先感谢。

这是cameraRecognitionObject类(https://www.cyberbotics.com/doc/reference/camera?tab-language=python#wb_camera_has_recognition)的定义
from controller import CameraRecognitionObject
class CameraRecognitionObject:
def get_id(self):
def get_position(self):
def get_orientation(self):
def get_size(self):
def get_position_on_image(self):
def get_size_on_image(self):
def get_number_of_colors(self):
def get_colors(self):
def get_model(self):
因此,一旦调用Camera.getRecognitionObjects,您将获得一个对象数组,并且可以轻松获取id和位置(与相机相比):
firstObject = Camera.getRecognitionObjects()[0]
id = firstObject.get_id()
position = firstObject.get_position()
