The control unit 50 further comprises an image database 51 and a comparison program 52, and the comparison program 52 further comprises a deep learning algorithm.
The first image capturing unit 10 is a dynamic visual sensor (Dynamic Vision Sensor, DVS) that records information in units of events. Specifically, the light intensity in the environment changes during the movement of the object, and the dynamic vision sensor can detect and record the change of the light intensity in the environment. Therefore, the first image capturing unit 10 is substantially configured to detect a change in light intensity when an object in the environment is moving, wherein the moving object can be defined as a moving object, and the change in light intensity in the environment can be defined as a dynamic image.
The second image capturing unit 20 is a general image sensor (e.g. RGB CMOS image sensor) that records images in units of frames, and the image content can be color pixels or black-and-white pixels. Therefore, the second image capturing unit 20 essentially records the images of the moving object and the surrounding environment thereof and recognizes the appearance of the moving object in the images.
The distance sensing unit 30 is an optical radar Sensor (LiDAR Sensor), an indirect time-of-flight Sensor (iToF Sensor), or a direct time-of-flight Sensor (dToF Sensor). Thus, the distance sensing unit 30 of the above type detects the distance of the moving object by optical radar, indirect time of flight, or direct time of flight.

The object detection technology is a computer technology related to computer vision and image processing for detecting a certain type of image and video, such as human beings, animals, buildings, or vehicles. Research fields of object detection include, for example, face detection and pedestrian detection, and object detection has applications in many fields of computer vision, including image retrieval and video surveillance. The first image capturing unit 10 or the second image capturing unit 20 of the present invention can detect the driver, the pedestrian, the animal in the environment, etc. in the image by using the object detection technology. Object detection methods are generally classified as neural network-based methods or non-neural methods. For non-neural methods, it is necessary to first define features using one of the following methods, and then classify the features using techniques such as support vector machines (support vector machine, SVM). On the other hand, neural technology is capable of object detection without explicitly defining features, and is typically based on convolutional neural networks (Convolutional Neural Network, CNN). Non-neural methods such as: the method is based on the characteristics of Hard digital images, such as a Viola-Jones target detection framework (Viola-Jones object detection framework based on Haar features), scale-invariant feature transform (Scale-INVARIANT FEATURE TRANSFORM, SIFT), a direction gradient histogram (Histogram of oriented gradients (HOG) features) and the like, but is not limited thereto; neural methods such as: R-CNN candidate region (Region Proposals (R-CNN)), single sample multi-frame detector (Single Shot MultiBox Detector, SSD), you need only look once (You Only Look Once, YOLO), single refinement neural network for target detection (Single-Shot Refinement Neural Network for Object Detection (REFINEDET)), retina-Net (Retina-Net), deformed convolutional neural network (Deformable convolutional networks), etc., but not limited thereto.
Behavior recognition, motion recognition or limb motion recognition is a technique for recognizing animal motions by using computer technology related to image acquisition and image processing. Because of its versatility, different fields may refer to behavior recognition as plan recognition, object recognition, intent recognition, location estimation, and the like. The behavior recognition is as follows: sensor-based single-user activity recognition (user activity recognition), sensor-based activity recognition level (Levels of Sensor-based activity recognition), sensor-based multiple-user activity recognition (multi-user activity recognition), and the like; the manner of behavior recognition is for example: activity recognition by logic and reasoning (Activity recognition through logic and reasoning), activity recognition by probabilistic reasoning (Activity recognition through probabilistic reasoning), data mining based activity recognition method (DATA MINING based approach to activity recognition), global positioning system based activity recognition (GPS-based activity recognition), but not limited thereto. The first image capturing unit 10 of the present invention can detect a specific dangerous behavior pattern of a moving object in an image by using a behavior recognition technology, such as dangerous actions of a driver, a person running a blank door or a non-intrusive forbidden zone, a wild animal invading a building, etc.
In summary, the behavior image sensing system of the present invention can determine the behavior pattern of the moving object through the dynamic image, and does not need to capture the static image of the static object, nor determine the behavior pattern of the static object, so that the data processing amount is reduced greatly, and the system is suitable for any environment.
Furthermore, the behavior image sensing system of the invention further judges the type of the moving object through the general image after determining the behavior mode of the moving object, thus completely eliminating the need of capturing the static image of the static object and judging the type of the static object, and reducing the data processing amount greatly.
In addition, the behavior image sensing system further calculates the distance of the moving object after determining the behavior mode or the class of the moving object, judges whether the distance of the moving object is smaller than a preset value, does not need to calculate the distance of the static object at all, does not need to judge whether the distance of the static object is smaller than the preset value, and reduces the data processing amount greatly.
In addition, the control unit 50 can control the alarm unit 40 to send out an alarm signal to drive away the moving object or inform the user according to the situation, so as to reduce the accident probability.
The above description is for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, but is intended to cover any and all modifications or variations of the present invention that fall within the spirit and scope of the invention.
