• Vilib.traffic_sign_detect_switch(False) : Switch ON/OFF traffic sign detection
The information detected by the target will be stored in the detect_obj_parameter = Manager().dict() dictio-
nary.
In the main program, you can use it like this:
Vilib.detect_obj_parameter['color_x']
The keys of the dictionary and their uses are shown in the following list:
• color_x: the x value of the center coordinate of the detected color block, the range is 0~320
• color_y: the y value of the center coordinate of the detected color block, the range is 0~240
• color_w: the width of the detected color block, the range is 0~320
• color_h: the height of the detected color block, the range is 0~240
• color_n: the number of detected color patches
• human_x: the x value of the center coordinate of the detected human face, the range is 0~320
• human_y: the y value of the center coordinate of the detected face, the range is 0~240
• human_w: the width of the detected human face, the range is 0~320
• human_h: the height of the detected face, the range is 0~240
• human_n: the number of detected faces
• traffic_sign_x: the center coordinate x value of the detected traffic sign, the range is 0~320
• traffic_sign_y: the center coordinate y value of the detected traffic sign, the range is 0~240
• traffic_sign_w: the width of the detected traffic sign, the range is 0~320
• traffic_sign_h: the height of the detected traffic sign, the range is 0~240
• traffic_sign_t: the content of the detected traffic sign, the value list is [‘stop’,’right’,’left’,’forward’]
• gesture_x: The center coordinate x value of the detected gesture, the range is 0~320
• gesture_y: The center coordinate y value of the detected gesture, the range is 0~240
• gesture_w: The width of the detected gesture, the range is 0~320
• gesture_h: The height of the detected gesture, the range is 0~240
• gesture_t: The content of the detected gesture, the value list is [“paper”,”scissor”,”rock”]
• qr_date: the content of the QR code being detected
• qr_x: the center coordinate x value of the QR code to be detected, the range is 0~320
• qr_y: the center coordinate y value of the QR code to be detected, the range is 0~240
• qr_w: the width of the QR code to be detected, the range is 0~320
• qr_h: the height of the QR code to be detected, the range is 0~320
