    Abstract: 一种航线规划方法、装置、设备、无人机及可读存储介质，其中该方法包括：获取拍摄作业的初始规划的多个拍摄点的第一位置信息(S101)；根据第一位置信息，估计无人机在任一拍摄点对目标地块拍摄形成的图像对应覆盖的地表区域的第二位置信息(S102)；根据第二位置信息确定地表区域的法向信息(S103)；根据法向信息调整拍摄点，以使调整后的每个拍摄点与对应地表区域之间的法向距离大致相等(S104)；根据调整后的多个拍摄点，规划无人机在目标地块内的拍摄作业航线(S105)，该方法能够提高航线规划的可靠性。

    Abstract: A photogrammetry system includes a memory, a processor, and a geo-positioning device. The geo-positioning device outputs telemetry regarding a vehicle on which one or more cameras are mounted. The processor can receive first telemetry from the geo-positioning device characterizing the vehicle telemetry at a first time, camera specification(s) regarding the cameras, photogrammetric requirement(s) for captured images, and a last camera trigger time. The processor can determine a next trigger time for the cameras based upon the received telemetry, camera specification(s), photogrammetric requirement s), and last trigger time. The processor can transmit a trigger signal to the camera(s) and the geo-positioning device to cause the camera(s) to acquire images of a target and the geo-positioning device to store second vehicle elemetry data characterizing the vehicle telemetry at a second time that is after the first time and during acquisition of the images. The processor can receive the acquired images from the cameras.

    Abstract: Methods and systems are disclosed including an imaging system comprising an image- capturing system having two or more image-capturing devices and positioned on a platform over a predefined target area at a first altitude above the Earth, the image-capturing devices configured to capture a set of images depicting contiguous, substantially contiguous, or partially overlapping geographic coverage sub-areas within the predefined target area, the image-capturing devices having variable focal lengths and variable fields of view; and a computer system selectively adjusting the orientation of the field of view of at least one of the image-capturing devices based at least in part on a change in the focal length of the image-capturing device(s).

    Abstract: An apparatus for evaluating a quality for image capture comprises a stored (101) for storing a model of a scene and a capture circuit (105) for generating virtual captured images for a camera configuration by rendering from the model. A depth generation circuit (107) generates model depth data from the model and a depth estimation circuit (111) generates estimated depth data from the virtual captured images. A first synthesis circuit (109) and a second synthesis circuit (113) generates first and second view images for test poses by processing the virtual captured images based on the model depth data or estimated depth data respectively. A reference circuit (103) generates reference images for the f test poses by rendering based on the model. A quality circuit (115) generates a quality metric based on a comparison of the first view images, the second view images, and the reference images.
