出现这个问题怎么解决：RuntimeError: Frame capture has timed out

出现这个问题怎么解决：RuntimeError: Frame capture has timed out.我是mv4 plus 运行的edgeimpulse的代码。

# Edge Impulse - OpenMV Image Classification Example

import sensor, image, time, os, tf

sensor.reset()                         # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565)    # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)      # Set frame size to QVGA (320x240)
sensor.set_windowing((240, 240))       # Set 240x240 window.
sensor.skip_frames(time=2000)          # Let the camera adjust.

net = "trained.tflite"
labels = [line.rstrip('\n') for line in open("labels.txt")]

clock = time.clock()
while(True):
    clock.tick()

    img = sensor.snapshot()

    # default settings just do one detection... change them to search the image...
    for obj in tf.classify(net, img, min_scale=1.0, scale_mul=0.8, x_overlap=0.5, y_overlap=0.5):
        print("**********\nPredictions at [x=%d,y=%d,w=%d,h=%d]" % obj.rect())
        img.draw_rectangle(obj.rect())
        # This combines the labels and confidence values into a list of tuples
        predictions_list = list(zip(labels, obj.output()))

        for i in range(len(predictions_list)):
            print("%s = %f" % (predictions_list[i][0], predictions_list[i][1]))

    print(clock.fps(), "fps")

运行hello world有没有问题？
使用的什么版本的固件？

pg1t

@kidswong999 hello world没问题 4.1.1

pg1t

@kidswong999 改了3.9.1版本又变成了RuntimeError: Capture Failed: -4

pg1t

@pg1t 3.9.2

kidswong999

你用的什么型号的硬件？我用OpenMV4 Plus没有出现问题。

pg1t

@kidswong999 就是openmv4plus啊。。。

kidswong999

单独运行这个代码有没有问题？

import sensor, image, time, os, tf

sensor.reset()                         # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565)    # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)      # Set frame size to QVGA (320x240)
sensor.set_windowing((240, 240))       # Set 240x240 window.
sensor.skip_frames(time=2000)          # Let the camera adjust.

clock = time.clock()
while(True):
    clock.tick()
    img = sensor.snapshot()

摄像头模组使用的是标配的OV5640？

pg1t

@kidswong999 我现在运行啥都是runtime error了 hello world也是。。。摄像头就是你说的那个

pg1t

@kidswong999 重新插拔就好了。离谱
