请参阅图1，图1是本发明提供的检测系统一实施例的结构示意图，如图1所示，该检测系统包括：传送模块101、与该传送模块101相连接的位置传感器102、光传感装置103、光源105以及处理器(图中未示出)。本实施例中，传送模块101为传送带，传送带用于传送目标检测物104，位置传感器102为位置编码器，位置编码器用于记录并存储目标检测物104与光传感装置103的位置坐标，并将位置坐标信息传输给处理器。光传感装置103包括旋转模块、设置在旋转模块上的线阵传感器1032、固定于线阵传感器1032一侧的遮光板1033，遮光板1033的高度与线阵传感器1032的光信号采集角度相适应。本实施例中，旋转模块为振镜，振镜包括相互连接的振镜片1031、电机1035，在振镜片1031上至少设置有一个转轴1034，电机1035用于带动振镜片1031围绕转轴1034旋转。目标检测物104位于光源105的照射范围内，目标检测物104会反射照射到其上的光线，进而线阵传感器1032接收物体反射的光线。其中，线阵传感器1032在跟随振镜片1031旋转时采集目标检测物104中至少一个物点不同方向的光信号，包括光信号的角度信息和光强信息，并传输给处理器。其中，物点指的是物体上的一点。处理器根据获取的位置坐标和光信息进行关联处理得到目标检测物的光场信息，进而计算景深和分辨率。
在一实施例中，为了采集到目标检测物104中至少一个物点不同方向的光信号，将目标检测物104放置在传送模块101上，启动传送模块101对目标检测物104进行传送，不启动电机1035对光传感装置103进行旋转，将位置编码器固定安装在传送模块101上，目标检测物104位于光源105的照射范围内。线阵传感器1032在目标检测物104移动的过程中采集并记录目标检测物104中至少一个物点不同方向的光信号，包括光信号的角度信息和光强信息，并将采集的光信号传输给处理器。同时，位置编码器记录并存储此过程中目标检测物104和光传感装置103的位置坐标，并将位置坐标信息传输给处理器。处理器根据获取的光信号和位置坐标信息进行关联处理，得到目标检测物104中不同物点所对应的光信号集合，光信号集合中包括物点不同方向光信号的角度信息和光强信息。其中，位置编码器在采集目标检测物104和光传感装置103的位置坐标的过程中，光传感装置103不旋转，光传感装置103的位置坐标不变，目标检测物104的位置坐标变化，从而线阵传感器1032采集并记录目标检测物104中至少一个物点不同方向的光信号，进而处理器通过关联处理得到目标检测物不同物点的光信号集合及光场信息，进而计算景深和分辨率。
具体地，请参阅图2.1，图2.1是本发明提供的光传感装置在某一时刻采集目标检测物上物点光信号的示意图。如图2.1所示，A、B、C分别代表目标检测物104上的三个不同的物点，A点与线阵传感器1032的连线代表此时刻线阵传感器1032采集到的来自物点A的光信号方向，B点与线阵传感器1032的连线代表此时刻线阵传感器1032采集到的来自物点B的光信号方向，C点与线阵传感器1032的连线代表此时刻线阵传感器1032采集到的来自物点C的光信号方向。线阵传感器1032通过采集此时刻物点A、B、C的光信号获取来自A、B、C光信号的光强信息，位置编码器同时记录并存储目标检测物104和光传感装置103的位置坐标，进而获得光传感装置103此时采集的分别来自物点A、B、C的光信号的角度信息。如图2.2所示，图2.2是本发明提供的光传感装置在另一时刻采集目标检测物上物点光信号的示意图。根据上述同样的方法得到另一时刻来自物点A、B、C的光信号的光强信息和角度信息。处理器根据得到的这两个时刻物点A、B、C光信号的角度信息和光强信息进行关联处理，分别得到物点A、B、C的光信号集合，物点A的光信号集合包括物点A在这两个时刻的两个光信号角度信息和两个光强信息，物点B的光信号集合包括物点B在这两个时刻的两个光信号角度信息和两个光强信息，物点C的光信号集合包括物点C在这两个时刻的两个光信号角度信息和两个光强信息。光信号采集过程中采集了多个时刻的光信号信息，从而处理器得到每一物点的包括多个角度信息和光强信息的光信号集合，得到目标检测物104的光场信息，进而计算景深。
在另一实施例中，将目标检测物104放置在传送模块101上，位置编码器固定安装在传送模块101上，不启动传送模块101对目标检测物104进行传送，启动电机1035带动振镜片1031绕转轴1034旋转，位于振镜片1031上的线阵传感器1032在跟随振镜片1031旋转时采集并记录目标检测物104中至少一个物点不同方向的光信号并传输给处理器，在线阵传感器1032采集并记录光信号的同时，位置编码器记录并存储目标检测物104和光传感装置103的位置坐标并传输给处理器，处理器根据获取的光信号和位置坐标信息进行关联处理得到目标检测物104中物点所对应的光信号集合，光信号集合中包括物点不同方向光信号的角度信息和光强信息。其中，位置编码器在采集目标检测物104和光传感装置103的位置坐标的过程中，光传感装置103旋转，光传感装置103的位置坐标变化，目标检测物104的位置坐标不变，从而线阵传感器1032采集并记录目标检测物104中至少一个物点不同方向的光信号，进而处理器通过关联处理得到目标检测物不同物点的光信号集合及光场信息，进而计算景深。
在其他实施例中，将目标检测物104放置在传送模块101上，位置编码器102固定安装在传送模块101上，启动传送模块101对目标检测物104进行传送，启动电机1035带动振镜片1031绕转轴1034旋转，位于振镜片1031上的线阵传感器1032在跟随振镜片1031旋转时采集并记录目标检测物104中至少一个物点不同方向的光信号并传输给处理器，在线阵传感器1032采集并记录光信号的同时，位置编码器102记录并存储目标检测物104和光传感装置103的位置坐标并传输给处理器，处理器根据获取的光信号和位置坐标信息进行关联处理得到目标检测物104中物点所对应的光信号集合，光信号集合中包括物点不同方向光信号的角度信息和光强信息。其中，位置编码器在采集目标检测物104和光传感装置103的位置坐标的过程中，光传感装置103旋转，光传感装置103的位置坐标变化，目标检测物104的位置坐标也变化，从而线阵传感器1032采集并记录目标检测物104中至少一个物点不同方向的光信号，进而处理器通过关联处理得到目标检测物不同物点的光信号集合及光场信息，进而计算景深。
由上述可知，本发明的光传感装置包括旋转模块以及设置在旋转模块上的线阵传感器，线阵传感器用于在跟随旋转模块旋转时采集并记录目标检测物中至少一个物点的不同方向的光信号。通过线阵传感器采集并记录目标检测物中至少一个物点的不同方向的光信号，并通过位置传感器记录并存储目标检测物与光传感装置的位置坐标，进而能够在获取目标检测物光场信息的同时，精确计算景深。
