Image processing apparatus, image processing system, and image processing method
摘要
說明書
A common technique known from the past such as a background difference method can be applied as the moving body detection.
As a result of the moving body detection process, as illustrated in
Further, a frame externally contacting the moving body, that is, a moving body detection frame can be also obtained.
Here, the moving bodies are certain objects moving to the last and may be a person, a car, or erroneous detection such as trembling of trees, and types thereof are unable to be specified.
Further, a plurality of moving bodies may be adjacent or overlapping to form a silhouette or may be regarded as one moving body object.
(Step S102)
After the moving body detection process in step S101, in step S102, the “first person detection process” is executed using a moving body detection result.
As described above, in order to alleviate an excessive processing load of the person detection process according to the related art, in the process of the present disclosure, a simple “first person detection process” with small computation is executed in advance, and a process of narrowing down a pixel region estimated to be a person, that is, a “first person candidate point” from a captured image is performed.
