question about camera.project and camera.unproject

[joshua19881228]

Hello,

I've written some code as follows

Code: [Select]


        print("0. width, height:", camera.sensor.width, camera.sensor.height)
print("1. camera.center:",camera.center)

print("2. camera.unproject(Metashape.Vector((2000,1500,0))):", camera.unproject(Metashape.Vector((2000,1500,0))))
print("3. camera.project(camera.center):", camera.project(camera.center))

and the result is

Code: [Select]

0. width, height: 4000 3000
1. camera.center: Vector([6.560932254872134, -0.915845546119054, 0.6655975799801932])
2. camera.unproject(Metashape.Vector((2000,1500,0))): Vector([6.560932254872134, -0.915845546119054, 0.6655975799801932])
3. camera.project(camera.center): None

what is the function of "camera.project"

Hello joshua,

camera.project method can be used to get the 2D pixel coordinates in the image space of the 3D point (defined in the internal coordinate system of the chunk).
