SENSOR DATA PROCESSING
First Claim
1. A method of processing sensor data, the method comprising:
- measuring a value of a first parameter of a scene using a first sensor to produce a first image of the scene;
measuring a value of a second parameter of the scene using a second sensor to produce a second image of the scene;
identifying a first point, the first point being a point of the first image that corresponds to a class of features of the scene;
identifying a second point, the second point being a point of the second image that corresponds to the class of features;
projecting the second point onto the first image;
determining a similarity value between the first point and the projection of the second point on to the first image; and
comparing the determined similarity value to a predetermined threshold value.

Abstract
A method and apparatus for processing sensor data comprising measuring a value of a first parameter of a scene using a first sensor (e.g. a camera) to produce a first image of the scene, measuring a value of a second parameter of the scene using a second sensor (e.g. a laser scanner) to produce a second image, identifying a first point of the first image that corresponds to a class of features of the scene, identifying a second point of the second image that corresponds to the class of features, projecting the second point onto the first image, determining a similarity value between the first point and the projection of the second point on to the first image, and comparing the determined similarity value to a predetermined threshold value. The method or apparatus may be used on an autonomous vehicle.

13. Apparatus for processing sensor data, the apparatus comprising:
-
a first sensor for measuring a value of a first parameter of a scene to produce a first image of the scene; a second sensor for measuring a value of a second parameter of the scene to produce a second image of the scene; and one or more processors arranged to; identify a first point, the first point being a point of the first image that corresponds to a class of features of the scene; identify a second point, the second point being a point of the second image that corresponds to the class of features; project the second point onto the first image; determine a similarity value between the first point and the projection of the second point on to the first image; and compare the determined similarity value to a predetermined threshold value. - View Dependent Claims (14, 15)
