Embodiment Construction

[0024] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0025] Three-dimensional information can also be called depth information or depth of field information. At present, the three-dimensional information measurement technology is mostly assisted by laser.

Abstract

The invention provides a target detection method and device. The method comprises the following steps: shooting a first image of an imaging space, wherein the first image comprises plane information of a target object in the imaging space; processing the first image to detect a target area including the target object; shooting a second image of the imaging space, wherein the second image comprises depth information of the target object; mapping a target area in the first image to a second image based on a relative position relationship between a first image sensor for shooting the first image and a second image sensor for shooting the second image; and calculating depth information in the target area in the second image. Therefore, a fast and accurate target detection scheme is provided by extracting the target area from the conventional image and limiting the depth calculation of the depth image in the extracted target area through mapping.

Description

technical field [0001] The invention relates to the field of image measurement and processing, in particular to a method and equipment for target detection. Background technique [0002] Three-dimensional information can also be called depth information or depth of field information. At present, the three-dimensional information measurement technology is mostly assisted by laser. For example, the spatial depth value of the surface of the target to be measured can be calculated by triangulation. The above-mentioned spatial depth values ​​can describe the characteristics of the target to be detected, and thus can be used for detection of target objects in a wide range of fields. [0003] However, due to the high computational density of depth information extraction, excessive power and computing power will be consumed in scenarios that require fast or large-scale target object detection. [0004] Therefore, a scheme capable of fast and accurate object detection is needed. ...
