Embodiment 1

[0024] The present invention provides a device for detecting objects of interest in a group target, the device is arranged opposite to the group target, and the device includes:

[0025] The light source 101, the light source is a white light source, used for illuminating the measured object formed by the group target;

[0026] a camera 102, the optical axis of the camera and the optical axis of the light source are vertically arranged, and are used for taking pictures of the measured object to obtain a sequence of images with multiple viewing angles and predetermined wavelengths;

[0027] The coated micro-lens array 103 is located in front of the camera lens, and the micro-lens array is coated according to a predetermined wavelength rule, and is used for acquiring multi-viewing angle predetermined wavelength image information;

[0028] Wherein, the microlens array is coated according to a predetermined wavelength rule. Specifically, according to the difference of the optical ...

Embodiment 2

[0058] In order to realize reliable detection of the target of interest in the scene, the present invention adopts the target detection device of interest in multiple groups of targets to detect the group targets from different positions and different perspectives. Finally, the three-dimensional distribution of the spatial scene under different viewing angles can be obtained. The number of interested target detection devices in the group target is not limited.

[0059] like figure 2 shown, figure 2 It is a schematic diagram of the layout of the target detection device of interest including 3 groups of targets. figure 2 The processing module is not shown in each group of devices in , but only a coaxial illumination imaging device composed of a light source 101 , a camera 102 , a half mirror 104 and a coated lens array 103 is shown. Each device surrounds the group target and is set opposite to the group target, and detects the target of interest from multiple angles.

Abstract

The invention discloses a method, a device and a system for detecting interested targets in group targets. The device comprises a white light source used for illuminating a measured object formed by group targets; the optical axis of the camera is perpendicular to the optical axis of the light source, and the camera is used for photographing the measured object to obtain a multi-view predeterminedwavelength image sequence; a coated microlens array which is located in front of the camera lens, and the microlens array is coated according to a preset wavelength rule and is used for acquiring multi-view preset wavelength image information; a semi-transmitting and semi-reflecting mirror which is arranged at an angle of 45 degrees with the illumination light path and the imaging light path andis used for realizing superposition of a light source optical axis and a camera optical axis through the semi-transmitting and semi-reflecting mirror; and a processing module which is connected with the camera and is used for processing the multi-view predetermined wavelength image sequence imaged by the camera and removing the shielding part of the interested target to obtain interested target information. By adopting the method, adverse effects caused by mutual shielding of multiple targets can be overcome, and reliable extraction of interested targets is realized.

Description

technical field [0001] The present invention relates to the technical field of image measurement, in particular to a method, device and system for detecting objects of interest in a group of objects. Background technique [0002] For multi-target spatial parameter testing problems such as penetrating body and effective fragments in the after-penetration area, high-speed photography detection method is an effective non-contact measurement method. However, the traditional imaging process is the integration of light radiation information in all directions of the object point in space, which cannot effectively distinguish light position and direction information, resulting in the lack of target spatial position information and insufficient information for after-effect parameter processing. [0003] On the other hand, in the prior art, an ordinary single-light source illumination method is usually adopted. Due to the severe occlusion between multiple targets in the after-effect a...
