我正在使用对象检测。我想同时计算对象。但我收到错误。你能帮忙吗?

错误:

    Traceback (most recent call last):
File "C:\tensorflow2\models\research\object_detection\Object_detection_image_say3.py", line 138,
in
<module>
v2.putText(input_frame, counting_mode, (10, 35), font, 0.8,
(0,255,255),2,cv2.FONT_HERSHEY_SIMPLEX)
SystemError: <built-in function putText> returned NULL without setting an error

主要代码:
我使用以下代码。我收到错误。
    input_frame = cv2.imread(PATH_TO_IMAGE)
image_expanded = np.expand_dims(input_frame, axis=0)

(boxes, scores, classes, num) = sess.run(
[detection_boxes, detection_scores, detection_classes, num_detections],
feed_dict={image_tensor: image_expanded})

font = cv2.FONT_HERSHEY_SIMPLEX

counting_mode = vis_util.visualize_boxes_and_labels_on_image_array(
input_frame,
np.squeeze(boxes),
np.squeeze(classes).astype(np.int32),
np.squeeze(scores),
category_index,
use_normalized_coordinates=True,
line_thickness=2,
min_score_thresh=0.80)

if(len(counting_mode) == 0):
cv2.putText(input_frame, "...", (10, 35), font, 0.8, (0,255,255),2,cv2.FONT_HERSHEY_SIMPLEX)
else:
cv2.putText(input_frame, counting_mode, (10, 35), font, 0.8,
(0,255,255),2,cv2.FONT_HERSHEY_SIMPLEX)
cv2.imshow('tensorflow_object counting_api',input_frame)
cv2.waitKey(0)

最佳答案

您的第二个 cv2putText 将counting_mode 作为输入
count_mode 不是字符串,因此无法显示

将您的counting_mode 对象转换为字符串(str),然后再将其注入(inject)cv2.putText

关于opencv - 我收到错误。我想反对计数,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/59612524/
