Method of processing sensor data for navigating a vehicle
First Claim
1. A method of processing sensor data for navigating a vehicle, the sensor data being from a sensor mounted on the vehicle, the method comprising:
- for a number of time-steps, measuring a value of a parameter of a scene using the sensor to produce a sequence of images of the scene;
using a computing device to determine a value of one or more image quality metrics in each image in the sequence, wherein computing said values of said image quality metrics does not include determining position values of the vehicle from the images; and
using the computing device to identify as either valid or invalid, a sub-sequence of images in the sequence based on an evolution of the determined image quality metric values within that sub-sequence.

Abstract
Apparatus for and method of processing sensor data for the purpose of navigating a vehicle (for example an autonomous or semi-autonomous vehicle), the sensor data being from a sensor (for example a camera) mounted on the vehicle. The method can include can include: for a number of time-steps, measuring a value of a parameter of a scene using the sensor to produce a sequence of images of the scene; determining a value of one or more image quality metrics (for example, spatial entropy and spatial information) in each image in the sequence; and identifying as either valid or invalid, a sub-sequence of images in the sequence based on the determined metric values.

11. Apparatus for processing sensor data for the purpose of navigating a vehicle, the apparatus comprising:
-
a sensor for mounting on the vehicle, the sensor being configured to, for a number of time-steps, measure a value of a parameter of a scene to produce a sequence of images of the scene; and one or more processors arranged to; determine a metric value of one or more image quality metrics in each image in the sequence, wherein computing said values of said image quality metrics does not include determining position values of the vehicle from the images; and identify as either valid or invalid, a sub-sequence of images in the sequence based on an evolution of the determined image quality metric values within that subsequence. - View Dependent Claims (12, 16)
