Precise angle estimation of capsule robot in ultrasound using heatmap guided two-stage network

•A heatmap guided two-stage network is proposed to detect the position and estimate the angle of the capsule robot in ultrasound images.•The proposed model develops the probability distribution and angle prediction modules to reduce the interference information in GI ultrasound images.•Our method ob...
