openmv如何实现主程序调用热点让手机能看到实时画面，脱机状态下需要使用几块锂电池能同时为云台，摄像，WiFi供电？

[e6tr]

主程序：
import sensor, image, time,network,usocket,sys
from pid import PID
from pyb import Servo
pan_servo=Servo(1)
tilt_servo=Servo(2)
red_threshold  = (0, 12, -128, 1, -128, 16)
pan_pid = PID(p=0.27, i=0, imax=90)
tilt_pid = PID(p=0.25, i=0, imax=90)

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # use RGB565.
sensor.set_framesize(sensor.QQVGA) # use QQVGA for speed.
sensor.skip_frames(10) # Let new settings take affect.
sensor.set_auto_whitebal(False) # turn this off.
clock = time.clock() # Tracks FPS.

def find_max(blobs):
    max_size=0
    for blob in blobs:
        if blob[2]*blob[2] > max_size:
            max_blob=blob
            max_size = blob[2]*blob[2]
    return max_blob


while(True):
    clock.tick() # Track elapsed milliseconds between snapshots().
    img = sensor.snapshot().lens_corr(1.8) # Take a picture and return the image.畸变校正

    blobs = img.find_circles(threshold = 3500, x_margin = 10, y_margin = 10,
 r_margin = 10,r_min = 2, r_max = 100, r_step = 2)#为识别到圆的区域:
    if blobs:
        max_blob = find_max(blobs)
        pan_error = max_blob[0]-img.width()/2
        tilt_error = max_blob[1]-img.height()/2
        #色块的xy左标
        print("pan_error: ", pan_error)

        img.draw_circle(max_blob.x(), max_blob.y(), max_blob.r(), color = (255, 0, 0))#画圆
        img.draw_cross(int(max_blob[0]),int(max_blob[1])) # cx, cy#画十字
       #PID计算
        pan_output=pan_pid.get_pid(pan_error,1)/2
        tilt_output=tilt_pid.get_pid(tilt_error,1)
        print("pan_output",pan_output)
        pan_servo.angle(pan_servo.angle()+pan_output)
        tilt_servo.angle(tilt_servo.angle()-tilt_output)

WIFI:
import sensor, image, time, network, usocket, sys
SSID ='OPENMV_AP'
KEY ='1234567890'
HOST = ''
PORT = 8080
sensor.reset()
sensor.set_contrast(1)
sensor.set_brightness(1)
sensor.set_saturation(1)
sensor.set_gainceiling(16)
sensor.set_framesize(sensor.QQVGA)
sensor.set_pixformat(sensor.RGB565)
wlan = network.WINC(mode=network.WINC.MODE_AP)
wlan.start_ap(SSID, key=KEY, security=wlan.WEP, channel=2)
def start_streaming(s):
print ('Waiting for connections..')
client, addr = s.accept()
client.settimeout(2.0)
print ('Connected to ' + addr[0] + ':' + str(addr[1]))
data = client.recv(1024)
client.send("HTTP/1.1 200 OK\r\n"
"Server: OpenMV\r\n"
"Content-Type: multipart/x-mixed-replace;boundary=openmv\r\n"
"Cache-Control: no-cache\r\n"
"Pragma: no-cache\r\n\r\n")
clock = time.clock()
while (True):
clock.tick()
frame = sensor.snapshot()
cframe = frame.compressed(quality=35)
header = "\r\n--openmv\r\n"
"Content-Type: image/jpeg\r\n"
"Content-Length:"+str(cframe.size())+"\r\n\r\n"
client.send(header)
client.send(cframe)
print(clock.fps())
while (True):
s = usocket.socket(usocket.AF_INET, usocket.SOCK_STREAM)
try:
s.bind([HOST, PORT])
s.listen(5)
s.settimeout(3)
start_streaming(s)
except OSError as e:
s.close()
print("socket error: ", e)

救急  希望大佬指点

WiFi扩展板和云台引脚冲突的。

[kidswong999]

如果是耗电问题的话，一个锂电池就行。

[e6tr]

@kidswong999 那怎样可以解决这一问题？还是说只能实现云台或者WIFI其中一个功能。

这个是WiFi图传的教程。

[kidswong999]

@e6tr 可以用舵机扩展板连接云台的舵机，但是也比较麻烦，代码要改。

@kidswong999 有没有可以参考的代码或视频，萌新不是很懂。。麻烦了
