下載kneron_plus_v2.1.1.zip

目前從Getting start開始study

跑到 Run Generic Image Inference With Post-process

我更換demo的圖片,會導致錯誤 , 請問有什麼需要注意的嗎?


user@ubuntu:~/kneron/kneron_plus/build/bin$ sudo ./kl520_demo_generic_image_inference_post_yolo

connect device ... OK

upload firmware ... OK

upload model ... OK

Error! malloc memory for image buffer failed

read image ... failed


starting inference loop 100 times

inference failed, error = 15 (Sending data (image) size exceeds firmware buffer size)

另外請問有camera的demo嗎? 如果有的話該如何執行

    Hi Shawn,

    "Sending data (image) size exceeds firmware buffer size" error是因為您的圖片超過KL520的firmware buffer size。

    您可以

    -試著用比較小的圖片，或是

    -參考kl520_demo_generic_data_inference.c，用kp_generic_data_inference_send來繞過這個限制。如果這個問題還是會出現的話，

    -調整fifoq_input_buf_size (最大可調640) 來調整送過去的image data buffer (包含header) 最大容納上限

    是的，我們camera的demo是kl520_demo_cam_generic_image_inference_drop_frame，會需要OpenCV，安裝方式可以參考這裡:

    Install Dependency - Document Center (kneron.com)

    Build的方式是:
