Problems solved by technology
The problem with this method is that when the color of the peripheral environment is roughly similar to the color of the human body, false recognition will occur.
However, in this method, the cost of the camera system increases substantially, and a large processing power is required

Embodiment Construction
[0016] Although the exemplary embodiment has been described using a plurality of units to perform the exemplary process, it is understood that the exemplary process may also be implemented by one or more modules. Furthermore, it can be understood that the term controller / control unit refers to a hardware device including a memory and a processor. The memory is configured to store the modules, and the processor is specifically configured to execute the modules to perform one or more processes that will be further described below.
[0017] Furthermore, the control logic of the present invention may be implemented as a non-transitory computer readable medium on a computer readable medium containing executable program instructions executed by a processor, controller, or the like. Examples of computer readable media include, but are not limited to, ROM, RAM, compact disc (CD)-ROMs, magnetic tapes, flash drives, smart cards, and optical data storage devices. The computer readable r...

The invention relates to a system and method for object image detection. The system comprises a light source controller configured to emit light rays toward a target or stop emitting light rays via one or more light sources and a target detection controller configured to detect the target via shadow produced on the target. The invention further comprises a method of utilizing the sytem for object target detection. The method comprises generating light source control signals via the light source controller to operate one the more light sources facing the target illuminated light rays, responsing the light source control signals, emitting light rays toward the target via the light source controller, collecting one or more image information via the target detection controller, collecting shadow information of the image information via the target detection controller, combing all the collected shadow information via the target detection controller to identify an outline of the target, so the target is detected.
Description
technical field [0001] The present invention relates to a system and method for detecting target images. Background technique [0002] Currently, there are many methods for using camera images to recognize objects, however, it is difficult to detect objects with high reliability in variable environments. In particular, misrecognition occurs due to external light sources and similar pattern images in target recognition, and this misrecognition has a large impact on the target detection rate. [0003] In general, there are various methods of identifying objects. The luminance-based object detection method facilitates detection by illuminating the target, extracting only camera images with a luminance of a predetermined level or higher (eg, threshold luminance). In this method, when the edge image is very bright or external light sources, such as sunlight, the target detection rate is basically relatively low. [0004] Another color-based object detection method is the metho...
