The invention discloses a reversing cold start image rapid display method, a computer device and a computer readable storage medium. The method comprises the steps of receiving a reversing instruction, obtaining a frame of image data sent by a camera device, sending the frame of image data to a memory of a camera serial interface, and setting a plurality of buffers into a double linked list; and identifying a second buffer in which a frame of image data is stored in the double linked list, identifying a third buffer with a storage space according to a subsequent pointer of the second buffer, sending the frame of image data in the memory to the third buffer, and sending the frame of image data in the second buffer to a display screen to display an image. The invention further provides a computer device for implementing the method and a computer readable storage medium. According to the invention, the time from cold start of a vehicle machine product to image display of the display screen can be reduced, and the situation that images displayed on the display screen are overlapped and even blurred in the preview rapid movement process of the camera device is avoided.
本发明公开一种倒车冷启动影像快速显示方法、计算机装置及计算机可读存储介质,该方法包括接收倒车指令,获取摄像装置发送的一帧图像数据,将一帧图像数据发送至相机串行接口的存储器中,将多个缓冲器设置成一个双向链表;识别出双向链表中已存储一帧图像数据的第二缓冲器,并根据第二缓冲器的后继指针识别出有存储空间的第三缓冲器,将存储器中的一帧图像数据发送至第三缓冲器,且将第二缓冲器中的一帧图像数据发送至显示屏进行显示图像。本发明还提供实现上述方法的计算机装置以及计算机可读存储介质。本发明能够减小车机产品冷启动后到显示屏显示图像的时间、避免摄像装置进行预览快速移动过程中显示屏上显示图像出现图像重叠甚至图像模糊的情况。
