easyidp.reconstruct.Sensor#

class easyidp.reconstruct.Sensor#

The base class of camera model

Methods

`__init__`()
`in_img_boundary`(polygon_hv[, ignore, log])	Judge whether given polygon is in the image area, and move points to boundary if specify ignore.

Attributes

`id`	the sensor id in this 3D reconstruction project, often only has one.
`label`	the sensor label/name, `<class 'str'>`
`type`	Sensor type in [frame, fisheye, spherical, rpc] (often for metashape project), `<class 'str'>`
`width`	The sensor width pixel number, `<class 'int'>`
`height`	The sensor height pixel number, `<class 'int'>`
`w_mm`	sensor actual width, unit is mm, `<class 'float'>`
`h_mm`	sensor actual height, unit is mm, `<class 'float'>`
`pixel_width`	the scale of one pixel width, unit in mm, `<class 'float'>`
`pixel_height`	the scale of one pixel height, unit in mm, `<class 'float'>`
`pixel_size`	the scale of one pixel, for pix4d, [pixel_height, pixel_width]
`focal_length`	focal length, unit in mm, `<class 'float'>`
`calibration`	sensor calibration information, `easyidp.Calibration`

id#: the sensor id in this 3D reconstruction project, often only has one. <class 'int'>

in_img_boundary(polygon_hv, ignore=None, log=False)#

Judge whether given polygon is in the image area, and move points to boundary if specify ignore.

Parameters:

polygon_hv (numpy nx2 array) – [horizontal, vertical] points in pixel coordinate
ignore (str | None, optional) –
Whether tolerate small parts outside image
- None: strickly in image area;
- x: only y (vertical) in image area, x can outside image;
- y: only x (horizontal) in image area, y can outside image.
Todo

This API will be enhanced and changed in the future.

ignore (str) -> ignore_overflow (bool):
- True: strickly in image area, default;
- False: cut the polygon inside the image range;
log (bool, optional) – whether print log for debugging, by default False

Return type:

None | polygon_hv

type#: Sensor type in [frame, fisheye, spherical, rpc] (often for metashape project), <class 'str'>
