1. 通过标记在模型中的已知点来确定相机位置，这些点应具有已知坐标。使用以下代码示例：

# Importing the PhotoScan libraries
import Metashape 

# Initializing the chunk
doc = Metashape.Document()
chunk = doc.addChunk()
chunk.addPhotos("path/to/photos") # Adding photos to chunk

# Adding markers with known coordinates
marker1 = chunk.addMarker()
marker1.reference.location = Metashape.Vector([1.234, 5.678, 9.012])
marker2 = chunk.addMarker()
marker2.reference.location = Metashape.Vector([3.456, 7.890, 1.234])

# Running the algorithm to determine camera positions
chunk.markers.update()
chunk.optimizeCameras()

2. 使用已知的相机间的外方位元素来确定相机位置。如下所示：

# Importing the PhotoScan libraries
import Metashape 

# Initializing the chunk
doc = Metashape.Document()
chunk = doc.addChunk()
chunk.addPhotos("path/to/photos") # Adding photos to chunk

# Adding known camera poses
cam1_pose = Metashape.Pose()
cam1_pose.rotation = Metashape.Matrix([[1, 0, 0], [0, 1, 0], [0, 0, 1]])
cam1_pose.translation = Metashape.Vector([1.234, 5.678, 9.012])
cam1 = chunk.addCamera()
cam1.reference.camera = cam1
cam1.reference.pose = cam1_pose

cam2_pose = Metashape.Pose()
cam2_pose.rotation = Metashape.Matrix([[1, 0, 0], [0, 1, 0], [0, 0, 1]])
cam2_pose.translation = Metashape.Vector([3.456, 7.890, 1.234])
cam2 = chunk.addCamera()
cam2.reference.camera = cam2
cam2.reference.pose = cam2_pose

# Running the algorithm to determine camera positions
chunk.optimizeCameras()
