Problems solved by technology

However, in the scanning LiDAR as in Patent Document 1, it is difficult to narrow the distance between sensing points, for example, due to the arrangement of light receiving elements, especially in the direction perpendicular to the scanning direction.
As a result, there is a concern that only less dense, or in other words lower resolution, detection data can be obtained

Abstract

The invention provides an image processing apparatus, an image processing method, an image processing program, and an image processing system. An image processing ECU (30) is an image processing device provided with an image acquisition unit (41), a matching processing unit (43), and a super-resolution processing unit (44). An image acquisition unit (41) acquires a reflected light image (ImR) and a background light image (Iml) in association with each other. A matching processing unit (43) prepares one of a plurality of reflected light images (ImR) and a background light image (Iml), for example, the background light image (Iml), and performs sub-pixel matching processing on these images. A super-resolution processing unit (44) prepares the other of the plurality of reflected light images (ImR) and the background light image (ImmL), for example, the reflected light image (ImR), and performs super-resolution processing on the plurality of reflected light images (ImR) using alignment information obtained by sub-pixel matching processing. A super-resolution processing unit (44) generates a high-resolution reflected light image (IHR) by super-resolution processing.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on Japanese Patent Application No. 2019-195549 for which it applied to Japan on October 28, 2019, and the content of the base application is cited in its entirety by reference. technical field [0003] The disclosure of this specification relates to the technology of image processing. Background technique [0004] For example, Patent Document 1 discloses LiDAR (Light Detection and Ranging) as a distance sensor capable of distance measurement. The LiDAR disclosed in Patent Document 1 measures the distance to the object by scanning the irradiated light with a scanning mirror and detecting the reflected light reflected by the surrounding object. [0005] Patent Document 1: Japanese Patent Publication No. 2019-520563 [0006] In the distance sensor, it is desirable to narrow the interval of each sensing point and obtain dense data. However, in the scanning-type LiDAR such as Patent Document 1, i...
